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.
