How to Install PoE IP Cameras to Cover Large Areas

Installing IP cameras to cover large areas can be a challenging task. In many cases, cameras are installed at locations without easy access to power outlets, and running power cables over long distances can be impractical and costly. Additionally, large areas often require IP cameras to be installed at considerable distances from the PoE switch, making it challenging to provide power and data connectivity to the cameras. Fortunately, there is a solution to this problem: long-range PoE switches.



Why Do You Need a Long-Range PoE Switch?


A long-range PoE switch is a network device that extends PoE beyond the standard 100m limits. With a long-range PoE switch, IP cameras can be installed at exte   nded distances, ranging from 250 meters to 800 meters, depending on the specific switch model. You can eliminate the need for dedicated power supplies and data connections at each camera location, which streamlines the installation process and reduces costs. Normally, power loss occurs  as electrical signals travel through cables, but the long-range PoE switch is designed to minimize voltage drop and deliver consistent power levels to connected devices over long distances.

  • 24-Port Long-Range PoE+ Switch

This 24-port long-range PoE+ switch features a dip switch to extend your PoE+ signal to 250M at up to 10Mbps (ports #1-16), and it also supports PoE transmission of up to 500M at 100Mbps on ports #17-24 when used with PoE extenders. Featuring a total power supply of 225W, it can deliver a maximum power of 30W per port. It has a dedicated Gigabit SFP port which enables you to create a high-speed fiber link over long distances and link another network switch in the higher layer.

How to Use the Long-Range PoE+ Switch?


Option 1: Enable the DIP Switch – 250M at 10Mbps

One method to extend the range of PoE is by enabling the dip switch on the 24-port long-range PoE+ switch, which allows the switch to operate in a mode that supports a longer range but at a lower data transmission rate.

Benefits: It provides a simple and cost-effective method to extend the range of your PoE signal up to 250 meters without involving any PoE extender, which is ideal for large areas where power and data connectivity may be challenging to achieve. Moroever, since the camera is directly connected to the long-range PoE switch using a continuous run of Ethernet cable, it highly reduces the points of failure. Although Ethernet cables are made to varying standards of quality, the typical Cat5 cables can last for at least 10 years if well maintained, which increases system stability.

Limitations: Enabling the dip switch reduces the data transmission rate to 10Mbps. This may affect the video quality and can lead to lower resolution or frame rates, particularly for high-resolution cameras. So it is essential to consider the bandwidth requirements of your video surveillance system. Secondly, this method may not be suitable for environments with high levels of electronic interference, such as industrial areas or places with heavy equipment. The extended range may be affected by signal degradation in these situations, resulting in a decrease in data transmission quality.

This option is suitable for camera systems that require long-distance connectivity but can still function with a lower data transfer rate. For instance, if you are setting up a surveillance system in a large outdoor area, such as a parking lot, where the cameras are primarily used for surveillance rather than real-time monitoring, enabling the dip switch can be a suitable choice. Since the video footage is recorded and reviewed later, the lower data transfer rate is acceptable.

How to Install:

  1. Connect the NVR and 24-port long-range PoE switch to the router separately using Ethernet cables or connect the NVR directly to the uplink port on the PoE switch.
  2. Take a 250-meter-long cable, connect one end to one of the PoE ports (#1-16) on the long-range PoE switch, and the other end to the IP camera.
  3. Power on the PoE switch and enable the dip switch to extend PoE to 250M.


Option 2: Use with a PoE Extender – 500M at 100Mbps

Another option to extend the range of PoE is by using a PoE extender in conjunction with a long-range PoE switch. It allows you to extend the transmission distance up to 500 meters while maintaining a data transfer rate of 100Mbps.

Benefits: By connecting a PoE extender to your long-range PoE switch, you can extend the range of your network without compromising on data transfer quality. With the combination of a long-range PoE switch and a PoE extender, power loss is minimized even over extended distances. It can power a 30W PTZ camera with no hassle spanning a distance of 300 meters. This reliability eliminates the need to worry about power outages and provides peace of mind, knowing that the cameras will consistently capture footage.

Limitations: However, using a PoE extender may also have some limitations. For example, it may increase the cost of the switch, as it requires additional hardware. And it inevitably introduces a potential failure point.

It’s particularly beneficial for applications that demand real-time monitoring or high-definition video streaming, such as 4K footage. It can also be used in large-scale IP camera systems to transmit multiple video streams simultaneously to different locations. Moreover, cameras capturing high frame rates, such as 30fps or more, will also demand more bandwidth for smoother video playback. In addition, if your IP camera has advanced video analytics features, such as object recognition, motion tracking or facial recognition, it may generate more data that needs to be transmitted.

How to Install:

  1. Attach one end of the Ethernet cable to the LAN port on the NVR and the other end to a LAN port on the router.
  2. Use a short patch cord to connect one of the Ethernet uplink ports on the 24-port PoE+ switch to the router.
  3. Connect an Ethernet cable (100~800m) from one of the long-range PoE ports (#17-24) on the switch to the input port of the PoE extender.
  4. Finally, use an Ethernet cable to connect the PoE extender to the IP camera. Repeat steps 3-4 to connect the rest of the IP cameras.

How to Extend Your PoE IP Camera beyond 100 Meters?

When it comes to installing IP cameras, it is essential to consider various factors such as range, power supply, and compatibility. Typically, PoE is the preferred method for powering IP cameras, as it offers a convenient and cost-effective solution to transmit power and data simultaneously through a single Ethernet cable, eliminating the need for additional power outlets and cables. However, PoE has its own limitations. The maximum distance supported by PoE is generally around 100 meters or 328 feet.

What are the Problems When Installing IP Cameras Over 100M?


When attempting to install PoE cameras over 100 meters, various problems can arise. One of the most significant issues is power loss. As the cable length increases, power dissipates along the line, resulting in insufficient power reac hing the IP camera. This can lead to camera malfunctions or even complete failure. Another problem is signal degradation. As the distance between the PoE switch and the IP camera increases, there is a higher chance of data loss or corruption, resulting in poor image quality or loss of video footage. Moreover, IP cameras require a certain amount of bandwidth to transmit video data over the network. When the cable length exceeds 100 meters, the available bandwidth may not be sufficient to support the video transmission, resulting in delays and dropped frames.

What is a PoE Extender?


A PoE extender is a great option for expanding the range of a PoE network beyond the typical 100-meter limitation. It receives power from the first PoE switch or injector, amplifies it, and then passes it along to the second device over an extended distance. The PoE extender allows a single Ethernet cable to carry both data and power, making it ideal for remote locations where an electrical outlet is not available or difficult to access. Moreover, it eliminates the need for extra cabling, saving installation costs.

  • Waterproof PoE Extender

Designed with an IP67 waterproof enclosure, this PoE extender withstands all weather conditions, such as rain, snow and extreme temperatures. Powered by an 802.3bt PoE switch, it can deliver a maximum of 60W of power, offering sufficient power for such as PTZ cameras and digital signage displays. It also supports 10/100Mbps data rates for installing 4K cameras, ensuring crystal-clear footage and buffer-free video streams. With its snap-fit and wall-mount feature, installation becomes hassle-free. The LED indicator also simplifies monitoring and ensures seamless operation.

Benefits of a PoE extender:

  1. Easy Installation: With a PoE extender, you can extend your network without the need for additional power outlets or electrical wiring. It simplifies the installation process, making it quicker and more convenient.
  2. Increased Network Coverage: By extending the reach of your PoE network, you can connect devices located far away from the PoE switch or power source. This allows for greater network coverage and flexibility in device placement.
  3. Optimized Power Distribution: The PoE extender ensures consistent power supply to remote devices, regardless of their distance from the PoE switch. It provides the necessary power to devices like IP cameras, ensuring they operate effectively.
  4. High Bandwidth: PoE extenders maintain the same data transfer speeds and network performance as the PoE network, which enables high-bandwidth devices to be connected over long distances without compromising on network performance.


How to Choose a PoE Extender?


The first step is to check the compatibility of the PoE extender with your existing PoE devices. Ensure that it supports the same PoE standard as your devices. Secondly, determine the distance you need to cover with the PoE extender. Look for an extender that can transmit power and data over the required distance without degradation. Consider the actual cable length as well as any obstacles or interference that may affect the signal. Thirdly, check the supported network speeds of the extender. Ensure it can handle the desired data transfer rates without slowing down the network. Fourthly, consider the total power budget of the PoE extender and ensure it has enough power to support your connected devices. Lastly, determine the number of devices you plan to connect to the PoE extender and choose one with an adequate number of Ethernet ports.

How to Use a PoE Extender?


Using the PoE extender is relatively straightforward. First, connect the PoE switch or the PoE NVR to the input port of the PoE extender using a standard Cat5e/Cat6 Ethernet cable. Then, connect the output port of the PoE extender to the IP camera using another Ethernet cable. The PoE extender will boost the power and data signals, allowing them to reach the IP camera accurately. If you’re using a network switch, then you’ll also need to add a PoE injector between the network switch and the PoE extender. The PoE extender requires power to operate, which is usually provided by a separate power source or another PoE device.



How Many PoE Extenders Will Be Needed?


The number of PoE extenders required can be calculated by estimating the maximum distance between the power source and the connected device. The general rule is to use one PoE extender for every 100M of distance since the maximum distance that a single PoE extender can cover is 100 meters. If the total distance between the power source and the final device is 500 meters, you would need four PoE extenders, as each extender extends the reach by an additional 100 meters. However, it is important to consider that each extender introduces some power loss, so it’s recommended to add a buffer and keep the number of PoE extenders to a minimum. If you are connecting a camera from around 1km away, the PoE extenders won’t help you. You’ll need a fiber PoE solution or a wireless setup.

How Can PoE Extenders be Daisy-Chained?


The PoE extenders can also be used in a daisy-chain configuration, where multiple extenders can be connected in series to achieve an even greater distance. However, when daisy-chaining PoE extenders, it’s crucial to ensure that the power budget is not exceeded. The power budget is the total amount of power available for PoE devices in a network. Each PoE extender consumes some power for its operation, so you should calculate the power requirements of all the connected devices and make sure the power source can provide sufficient power. To daisy-chain PoE extenders, you need to connect the output port of one PoE extender to the input port of the next PoE extender using Ethernet cables. The first extender in the chai  n should be connected directly to the power source, while the final extender should be connected to the powered device. Each extender should be properly configured and powered to ensure the smooth transmission of data and power throughout the network.

Moreover, Fastcabling has also lunched a 300M PoE Ethernet Extension Kit, which enables you to effectively extend PoE up to 500 meters using only two PoE extenders, reducing the number of extenders used, points of failure and power loss over long cable runs.

Installation Tips


  1. Water Ingress: When installing PoE cameras outdoors, it’s crucial to protect them from water ingress. Make sure to fasten the cable glands tightly on both sides of the PoE extenders and use PoE extenders specifically designed for outdoor use. This will prevent water damage to the cables and extender, ensuring long-term reliability.
  2. Surge Protection: IP cameras are vulnerable to power surges caused by lightning strikes or other electrical disturbances over long cable runs. Therefore, it is vital to install surge protectors for both the PoE switch and the PoE extender to safeguard the IP camera and other connected devices from potential damage.
  3. Compatibility Issues: Before purchasing a PoE extender, ensure that it is fully compatible with your PoE switch and IP camera. Different devices may use different PoE standards, so check the specifications to ensure seamless integration.
  4. Limited Power Capacity: Some IP cameras may require higher power consumption due to additional features such as PTZ functionality or built-in heaters. In such cases, it’s advisable to use a pure copper cable rather than a CCA cable, as it offers better power transmission capabilities. Additionally, consider using a high-power PoE switch to provide sufficient power to the extended IP camera.

What is the Basic of Power Over Ethernet?

Power over Ethernet (PoE) is a technology that allows the transmission of both power and data over a single Ethernet cable. This innovative solution simplifies installations, reduces costs and provides flexibility in where devices can be placed. In this blog, we will delve into the basics of PoE and how it works.

Everything You Need to Know About PoE


Let’s start by understanding the key components of PoE. The two main elements are the power sourcing equipment (PSE) and powered device (PD). The PSE generates electrical power and sends it to the PD, which consumes the power to run the device. These devices can vary from VoIP phones and wireless access points to security cameras and IoT devices. Moreover, the PSEs can be further divided into endspan and midspan depending on how they supply power to devices. Endspan refers to Ethernet switches that are designed to supply power directly to PoE-enabled devices without the need for any additional equipment, such as the PoE switch. On the other hand, midspan refers to a PoE injector that is installed between the Ethernet switch and the PD. It’s often used in situations where an existing Ethernet switch does not have PoE capabilities, or where additional power is needed beyond what the switch can provide.

What’s Power Budget? PoE Standards?


The power budget refers to the maximum power a PSE can deliver to all connected devices simultaneously. This ensures that the PSE does not overload and cause power disruptions. Before implementing PoE, it’s important to calculate the power requirements of all connected devices. The most common standards are IEEE 802.3af and IEEE 802.3at, also known as PoE and PoE+. The key difference between the two is the amount of power they can provide. IEEE 802.3af can deliver up to 15.4 watts of power, while IEEE 802.3at can deliver up to 30 watts. This allows PoE+ to power devices with higher power requirements, such as pan-tilt-zoom (PTZ) cameras.



How does PoE Work?


To transmit power and data together, PoE utilizes unused wires in the Ethernet cable, specifically the spare pairs. Traditionally, Ethernet cables consist of four twisted pairs, but modern Ethernet networks only require two pairs for data transmission. This leaves the other two pairs free for PoE power transmission. By using the spare wires, PoE does not interfere with data transmission or the network’s performance. To implement PoE, both PSE and PD must be PoE-compatible. The PoE switch or PoE injector can automatically detect if a connected device requires power and, if so, supply it accordingly. Likewise, PDs must be designed to accept power over an Ethernet connection. If a device is not PoE compatible, an external PoE splitter or injector can be used to convert the power from an Ethernet port into a usable DC power supply for the device.

What Are the Benefits of PoE?


First and foremost, PoE simplifies installations by eliminating the need for additional power cables. PoE also provides flexibility in device placement, allowing devices to be installed in locations where power outlets may not be readily available. Additionally, PoE enables centralized power management and monitoring. PSEs can remotely monitor the power consumption of connected devices, allowing for better energy management and troubleshooting. This capability also facilitates easy device rebooting if necessary, without the need to physically access the device.

What Are the Drawbacks of PoE?


One of the main drawbacks of PoE is limited to a range of around 100 meters, which may not be enough for larger buildings or outdoor installations. Another drawback of PoE is the potential for power loss. As power is transmitted over the Ethernet cable, there is the potential for power loss due to cable resistance, which can reduce the power available to the device. This can be mitigated by using high-quality cables and PSE, but it is still a consideration. 

Is PoE Safe to Use?


PoE is generally safe to use when implemented correctly. However, like any electrical system, PoE does carry some risks that need to be considered. One of the potential hazards of PoE is electric shock. If the cabling used for PoE is damaged or frayed, it can become a safety hazard. Additionally, if the connected device is not designed to handle the amount of power being supplied through PoE, it can cause damage or create a safety hazard. Another potential concern is that PoE can generate heat, which can damage connected devices if proper ventilation is not provided.

However, these risks can be mitigated through proper installation and use of PoE equipment. For example, it’s important to use properly rated cables and connectors, and to make sure that the equipment is installed in a well-ventilated area. And you can opt for active PoE instead of passive PoE. Active PoE refers to a type of PoE that uses a negotiation process between the PSE and the PD to determine the amount of power that should be delivered, ensuring that the connected device receives the appropriate amount of power and reduces the risk of damage or safety hazards.



Which Type of Cable Should I Use?


When it comes to PoE installations, it’s generally recommended to use solid copper cables rather than copper-clad aluminum (CCA) cables. This is because CCA cables have a higher resistance than solid copper cables, which can result in more power loss, lower voltage and potentially higher temperatures. This can reduce the efficiency of the PoE installation and increase the risk of damage or safety hazards. The two most common types of pure copper cable used for PoE are Cat5e and Cat6 cables. Cat5e cable supports data rates of up to 1Gbps, while Cat6 cable is rated to handle up to 100 meters of cable length and supports data rates of up to 10 Gbps.

Starlink via Fiber Optics to Multiple Buildings

Background

Internet connectivity has become a necessity for most businesses and individuals. However, there are still many areas without reliable internet access, especially in rural and remote locations. Starlink aims to provide high-speed internet access to these areas using a network of low Earth orbit satellites. The Starlink system is designed to be an affordable and reliable solution for Internet connectivity in areas where traditional Internet service providers (ISPs) are not available or are too expensive. 

Customers Requests

One of our customers sought to connect multiple buildings located over a large area, including a school, a library, and a community center. They required a seamless and reliable connection that could effectively extend Starlink’s coverage to each building, enabling smooth communication, data transfer, and other online activities among the faculty and staff. Each location has a WiFi router installed, with the distance ranging from 900~1600 ft to the Starlink.

Challenges

Starlink routers are typically designed for wireless communication with the satellites.  Unlike traditional WiFi routers, they do not provide Ethernet ports, which makes it difficult to expand the network to multiple locations. Workstations that require a reliable and high-speed Internet connection for tasks such as video conferencing, large file transfers, or other data-intensive activities may face limitations without Ethernet connectivity.

Moreover, extending the service to multiple buildings may require additional wiring or cabling solutions to connect the terminal to the routers or other network equipment in each building. The distance between these locations can span several hundred meters or more, and traditional Ethernet solutions typically have limitations regarding distance capabilities (usually limited to 100 meters or 328 ft).

Solution: Expand Starlink over Fiber Optic Cables

So, why extend Starlink over fiber optic cables? Firstly, fiber optic cables provide significantly higher bandwidth to handle large amounts of data at blazing-fast speeds. Secondly, they can transmit data over much longer distances (up to 20km or more) without signal degradation, ideal for connecting multiple buildings in a large area. Thirdly, these cables do not emit electromagnetic signals that can be easily intercepted,  which can be more susceptible to eavesdropping. Moroever, fiber optic cables are not susceptible to corrosion or rust, and they’re resistant to environmental factors such as moisture and temperature fluctuations, contributing to reliable network performance over the long term.

To implement Starlink via fiber, the following equipment is necessary:

  • Ethernet Adapter: It allows the Starlink dish to connect to the fiber optic switch.
  • Fiber Optic Switch: A switch acts as the central hub to connect multiple fiber cables. It facilitates seamless communication between the buildings, enabling effortless data transmission and improved network performance.
  • Fiber Media Converters: They’re used to convert the optical signals transmitted through fiber optic cables into Ethernet signals compatible with the local network infrastructure, eliminating the need for a complete overhaul.
  • BiDi SFP Modules: These modules are used to connect the fiber optic cables to the media converters and switch. They enable bi-directional communication over a single fiber, saving cost and time.
  • Direct-Burial Fiber Cables: The backbone of the solution, the fiber optic cable, connects various network equipment between the buildings, ensuring high-speed data transfer. 100% factory-terminated with connectors already attached, these cables can be easily deployed between buildings without the need for extensive splicing. Surrounded by a steel armored strength member, they can be buried directly underground without the need for a conduit or innerduct, ideal for use in pipelines, oil and gas fields, heavy industrial sites

The first step involved mapping out the buildings’ locations and determining the shortest possible route for laying the fiber optic cables between the buildings. Factors like obstacles, potential signal deterioration, and deployment costs were carefully considered. Where possible, underground trenches need to be dug to house the cables. In areas where underground cabling was impractical, the fiber optic cables can be mounted on poles, using appropriate support brackets.

To connect the Starlink router to a fiber optic switch, you need to power off the router, disconnect the dish cable from the bottom, and then connect the Ethernet adapter via the USB port. Next, plug the dish cable into the corresponding port of the Ethernet adapter. Finally, connect an Ethernet cable from its Ethernet port to one of the RJ45 uplink ports on the fiber optic switch.

Once the adapter settings are configured, you can proceed with extending Starlink’s connectivity to the desired locations. First, insert a BiDi SFP module into the fiber optic switch and make sure it aligns properly. Secondly, connect the pre-installed fiber optic cable to the SFP module and gently push it in until it clicks into place. Connect the other end of the fiber cable to the second BiDi SFP module. Thirdly, plug the second SFP module into the SFP slot of the fiber media converter, and make sure it’s securely seated in the slot. Finally, connect the WiFi router to the media converter using an Ethernet cable, and power on the system. Repeat the same steps to establish the network connections to the other two buildings.



Topology

Results

The fiber optic infrastructure provided a reliable and high-speed internet connection to all buildings, overcoming the limitations of a wireless-only setup. Users in each building now had access to the global reach of Starlink, enhancing collaboration and information exchange across the organization.

It is a device that can convert the signals between copper and fiber optic cables, allowing for high-speed data transfer over long distances, suitable for larger office complexes or buildings further apart.

With a 10G media converter, the network can achieve speeds of up to 10 gigabits per second, allowing for faster and more efficient data transfer between office buildings. This enhanced bandwidth ensures that employees can perform data-intensive tasks such as video conferencing, cloud computing and data backup, without experiencing bottlenecks or slowdowns.

Moreover, it eliminates the need to replace all the existing network equipment as they are compatible with various network interface cards and switches, significantly reducing costs associated with a complete network overhaul. While upgrading a network may sound expensive, a 10G network will eventually pay off in the long run. By investing in the right equipment, businesses can avoid frequent upgrades or additional investments to accommodate increasing bandwidth demands.

How to Install a 10G Network Between Two Buildings?

Building a 10G point-to-point fiber optic network between two buildings requires careful planning and installation. First, we need to gather the necessary equipment for the setup:

  • 10G Media Converters: These devices convert electrical signals into optical signals and vice versa. Choose a pair of converters that support 10G connectivity.
  • BiDi SFP+ Modules: These modules are used to interface with the media converters, and they enable bi-directional communication on a single fiber.
  • Pre-terminated Fiber Cables: These cables come with connectors already attached, saving installation time and effort.
  • Fiber Enclosures and Patch Panels: These hardware items provide protection and organization for the fiber connections.

Secondly, plan the path for the fiber cables, avoiding obstacles and potential sources of interference. Consider both underground and aerial routes, taking into account any required permits or approvals for trenching or cable installation. Place conduit or innerduct if necessary, for protection and easy future maintenance. Then, carefully lay the fiber cables along the planned route, making sure to leave some slack at each end for termination.

Thirdly, install the 10G media converters in their designated locations, and insert the BiDi SFP+ modules into the SFP slots of the media converters. Next, connect one end of the fiber cable to the SFP+ module on each media converter. Take extra care to avoid bending or stressing the fiber cable during connection.

Lastly, connect the 10G media converters to a power source and power them up. Use appropriate network testing equipment, like an optical time-domain reflectometer (OTDR), to measure signal loss and verify the integrity of the fiber connection.

If you are looking to install IP cameras for your security system, you may have come across the term PoE NVR. The PoE NVR is a device that combines the functionality of a network video recorder with the capability to provide power to IP cameras over a single Ethernet cable, which eliminates the need for separate power cables for each camera. However, the PoE NVR can only transmit data up to a distance of 100 meters, which may not be sufficient for certain installations where cameras need to be placed far away. To overcome this challenge, a PoE extender can be used.

Whats a PoE Extender and How to Choose?


With a PoE extender, you can effortlessly extend the range of your IP camera. The PoE extender is a device that allows you to extend the range of your PoE network beyond the standard 100 meters. It works by receiving power and data from the PoE switch or injector and then transmitting it to the remote device over a longer distance. When choosing a PoE extender, there are a few factors to consider.

1.Power Budget

Evaluate the power requirements of your IP camera and choose a PoE extender that can deliver the required power. Calculate the total power consumption of your camera, including any additional devices, and verify that the extender’s power budget is sufficient to support your setup. But it’s worth mentioning that if your PoE NVR can only provide up to 15 watts of power, using a high-power PoE extender will not help. PoE extenders work by extracting power from the incoming PoE signal, boosting it, and then injecting it back into the cable. The total power available is still limited to what the original PoE source (PoE NVR) can provide.

2.Bandwidth Capacity

The PoE extender should have sufficient bandwidth capacity to support high-quality video streaming from the IP camera. It should not cause any degradation in the video quality or introduce significant latency. Some PoE extenders offer Gigabit Ethernet ports, which can provide higher data transmission rates, minimizing any potential video lag or latency issues. But if your PoE NVR can only support 10/100Mbps, the data rate will be limited to 100Mbps as the speed of a network is determined by the slowest link in the chain.

3.The Number of Ports

A multi-port PoE extender allows you to easily expand your network by supporting additional PoE devices. For example, a two-port PoE extender can extend the power and data signals for two IP cameras simultaneously. This can be useful if you have multiple cameras in close proximity that need to be extended. However, it should be noted that the number of IP cameras connected to the PoE NVR should not surpass its available channels. The PoE NVR may not have enough processing power, memory, or storage capacity to handle additional cameras. Moreover, connecting two cameras to a single PoE port on a PoE NVR is generally not recommended. It may exceed the power capacity of the PoE port, leading to insufficient power for proper operation.

How to Extend the PoE NVR with a PoE Extender?

Now, let’s explore how to use a PoE extender to extend the distance between the PoE NVR and the IP camera.

1.Use a Single Waterproof PoE extender


In this setup, you can connect the PoE extender directly to the PoE NVR using an Ethernet cable. The extender then amplifies the power and data signals and transmits them over another Ethernet cable to the IP camera. This allows you to extend the distance by an additional 100 meters.

Waterproof PoE Extender

Designed with an IP67 waterproof enclosure, this PoE extender withstands all weather conditions, such as rain, snow and extreme temperatures. Powered by an 802.3bt PoE switch, it can deliver a maximum of 60W of power, offering sufficient power for such as PTZ cameras and digital signage displays. It also supports 10/100Mbps data rates for installing 4K cameras, ensuring crystal-clear footage.

2.300 Meters Direct Burial PoE Ethernet Extension Kit


This kit includes 2x waterproof PoE extenders that can be daisy-chained together to extend the distance by up to 500 meters. To set up your system, start by connecting the output port of the first PoE extender to one of the PoE ports on the PoE NVR. Following that, obtain a sufficiently long Ethernet cable to reach the second PoE extender. Connect one end to the input port of the first PoE extender, and the other end to the input port of the second PoE extender. Finally, connect the second PoE extender to your IP camera.

How to Extend the PoE NVR for a High-Power PTZ Camera?


The maximum power output of a PoE NVR is generally limited to 25.5W. For devices that require more power to operate, such as a high-performance PTZ (Pan-Tilt-Zoom) camera that has a built-heater, you should consider adding a high-power PoE injector to the PoE NVR system. It allows you to provide dedicated, higher power to the PTZ camera without straining the power budget of the PoE NVR. Moreover, If the PTZ camera is located at a considerable distance from the NVR, the power delivered over the Ethernet cable can diminish. A high-power PoE injector can compensate for power loss over longer cable runs.

First, take a short patch cord and connect one end to the PoE port of the PoE NVR and the other end to the LAN port of the PoE injector. Power on the PoE NVR and the PoE injector. Next, use an Ethernet cable to connect the PoE output port of the PoE injector and the input of the PoE extender. Lastly, connect the IP camera to the PoE extender.

How to Install PoE IP Cameras to Cover Large Areas?

Installing IP cameras to cover large areas can be a challenging task. In many cases, cameras are installed at locations without easy access to power outlets, and running power cables over long distances can be impractical and costly. Additionally, large areas often require IP cameras to be installed at considerable distances from the PoE switch, making it challenging to provide power and data connectivity to the cameras. Fortunately, there is a solution to this problem: long-range PoE switches.

Why Do You Need a Long-Range PoE Switch?

A long-range PoE switch is a network device that extends PoE beyond the standard 100m limits. With a long-range PoE switch, IP cameras can be installed at extended distances, ranging from 250 meters to 800 meters, depending on the specific switch model. You can eliminate the need for dedicated power supplies and data connections at each camera location, which streamlines the installation process and reduces costs. Normally, power loss occurs as electrical signals travel through cables, but the long-range PoE switch is designed to minimize voltage drop and deliver consistent power levels to connected devices over long distances.

  • 24-Port Long-Range PoE+ Switch

This 24-port long-range PoE+ switch features a dip switch to extend your PoE+ signal to 250M at up to 10Mbps (ports #1-16), and it also supports PoE transmission of up to 500M at 100Mbps on ports #17-24 when used with PoE extenders. Featuring a total power supply of 225W, it can deliver a maximum power of 30W per port. It has a dedicated Gigabit SFP port which enables you to create a high-speed fiber link over long distances and link another network switch in the higher layer.

How to Use the Long-Range PoE+ Switch?




Option 1: Enable the DIP Switch – 250M at 10Mbps

One method to extend the range of PoE is by enabling the dip switch on the 24-port long-range PoE+ switch, which allows the switch to operate in a mode that supports a longer range but at a lower data transmission rate.

Benefits: It provides a simple and cost-effective method to extend the range of your PoE signal up to 250 meters without involving any PoE extender, which is ideal for large areas where power and data connectivity may be challenging to achieve. Moroever, since the camera is directly connected to the long-range PoE switch using a continuous run of Ethernet cable, it highly reduces the points of failure. Although Ethernet cables are made to varying standards of quality, the typical Cat5 cables can last for at least 10 years if well maintained, which increases system stability.

Limitations: Enabling the dip switch reduces the data transmission rate to 10Mbps. This may affect the video quality and can lead to lower resolution or frame rates, particularly for high-resolution cameras. So it is essential to consider the bandwidth requirements of your video surveillance system. Secondly, this method may not be suitable for environments with high levels of electronic interference, such as industrial areas or places with heavy equipment. The extended range may be affected by signal degradation in these situations, resulting in a decrease in data transmission quality.

This option is suitable for camera systems that require long-distance connectivity but can still function with a lower data transfer rate. For instance, if you are setting up a surveillance system in a large outdoor area, such as a parking lot, where the cameras are primarily used for surveillance rather than real-time monitoring, enabling the dip switch can be a suitable choice. Since the video footage is recorded and reviewed later, the lower data transfer rate is acceptable.

How to Install:

  1. Connect the NVR and 24-port long-range PoE switch to the router separately using Ethernet cables or connect the NVR directly to the uplink port on the PoE switch.
  2. Take a 250-meter-long cable, connect one end to one of the PoE ports (#1-16) on the long-range PoE switch, and the other end to the IP camera.
  3. Power on the PoE switch and enable the dip switch to extend PoE to 250M.

Option 2: Use with a PoE Extender – 500M at 100Mbps

Another option to extend the range of PoE is by using a PoE extender in conjunction with a long-range PoE switch. It allows you to extend the transmission distance up to 500 meters while maintaining a data transfer rate of 100Mbps.

Benefits: By connecting a PoE extender to your long-range PoE switch, you can extend the range of your network without compromising on data transfer quality. With the combination of a long-range PoE switch and a PoE extender, power loss is minimized even over extended distances. It can power a 30W PTZ camera with no hassle spanning a distance of 300 meters. This reliability eliminates the need to worry about power outages and provides peace of mind, knowing that the cameras will consistently capture footage.

Limitations: However, using a PoE extender may also have some limitations. For example, it may increase the cost of the switch, as it requires additional hardware. And it inevitably introduces a potential failure point.

It’s particularly beneficial for applications that demand real-time monitoring or high-definition video streaming, such as 4K footage. It can also be used in large-scale IP camera systems to transmit multiple video streams simultaneously to different locations. Moreover, cameras capturing high frame rates, such as 30fps or more, will also demand more bandwidth for smoother video playback. In addition, if your IP camera has advanced video analytics features, such as object recognition, motion tracking or facial recognition, it may generate more data that needs to be transmitted.

How to Install:

  1. Attach one end of the Ethernet cable to the LAN port on the NVR and the other end to a LAN port on the router.
  2. Use a short patch cord to connect one of the Ethernet uplink ports on the 24-port PoE+ switch to the router.
  3. Connect an Ethernet cable (100~800m) from one of the long-range PoE ports (#17-24) on the switch to the input port of the PoE extender.
  4. Finally, use an Ethernet cable to connect the PoE extender to the IP camera. Repeat steps 3-4 to connect the rest of the IP cameras.

Moreover, our series of long-range PoE+ switches also support 4-pair PoE technology, which allows farm owners to install high-power security cameras (30W max.) with pan-tilt-zoom (PTZ) functionalities at a vast distance of up to 400~500 meters when used with a PoE extender. Besides, if you already have a Cisco network switch in the warehouse or barn, you can also connect it to the long-range PoE ports on the new switch, effectively extending the distance beyond the standard 100-meter limitation.

2.Install PoE Surge Protectors in Outdoor Applications

To safeguard surveillance equipment from lightning strikes and power surges, it is crucial to integrate PoE surge protectors into the network infrastructure. These surge protectors act as a barrier, diverting excess energy away from the cameras and other network equipment. By effectively grounding the system and implementing surge protection measures, the risk of damage due to lightning strikes and power surges can be minimized.

The PoE surge protectors are typically installed between the power source, such as a PoE switch, and the connected devices. They actively monitor the power supply and safely redirect excessive voltage by creating a low-resistance path for the surge to flow away from the IP cameras. By installing surge protectors on both sides of a PoE network, the likelihood of camera malfunctions or downtime due to power-related issues can be significantly reduced.

Designed to withstand even the harshest weather conditions, this outdoor PoE surge protector (IP68-rated) operates reliably in a temperature range from -40°C to 85°C. With a high surge protection rating of 16kV and a fast response time of 5ns, it can effectively protect your value network equipment against power surges and transient voltages.

3.Incorporate Passive PoE Converters for Legacy Cameras

To address compatibility issues with passive PoE cameras, the integration of 24V passive PoE converters into the system is essential. While long-range PoE switches are optimized for 4-pair PoE, passive PoE cameras typically operate on a 2-pair system. Therefore, utilizing passive PoE converters allows seamless integration and support for the cameras’ power requirements. 

The 24V passive PoE converters are specifically designed to convert standard PoE to passive PoE. They work by automatically adjusting voltage levels and adapting the power delivery to meet the requirements of the connected device. The inclusion of 24V passive PoE converters allows farms and ranches to leverage existing camera infrastructure without the need for expensive replacements.
