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.
