How to Extend PoE NVR for an IP Camera?

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.
