An NVR (Network Video Recorder) system with IP cameras provides centralized video controls to easily view, manage, and store videos, which has been widely used in camera surveillance projects. How to realize the NVR connection with IP cameras? Is the PoE switch required in the connection? Then how to connect the PoE switch to NVR?

What Is NVR?

An NVR is a specialized computer system that includes a software program. It is usually used in an IP video surveillance network to receive live images or video streams, and record them digitally to a hard disk, USB flash drive, or other mass storage device. Users can view, playback, and download recordings when needed. Usually, based on Windows or Linux environments, the NVR has a user-friendly interface for day-to-day use, and is equipped with intelligent motion detection and camera control capability. Remote access is also available with NVR, and other benefits include the capability of handling large amounts of video streams, simple installation, and so on. Then how easy the installation is? The following offers two options for setting up NVR for IP cameras, including PoE NVR connections and non-PoE NVR connections.

How to Set Up NVR for IP Cameras?

PoE NVR and NVR without PoE are two NVR types on the market. They use different connection methods for IP cameras. Note that, it’s important to check the R supports, compatibility between the NVR and IP cameras when setting up NVR for IP cameras. First, make sure that the network video recorder supports the IP cameras that you intend to use. Second, make sure the NVR supports the resolution of the cameras because not all NVRs support 4K security cameras or 12MP cameras at present. Once the camera’s resolution is higher than the resolution that the NVR supports, the users have to access the web interface of the IP camera and reduce its resolution.

Option One: Connecting PoE NVR for IP Cameras Without PoE Switch

PoE NVR has a built-in PoE switch, offering Ethernet ports for connecting IP cameras directly. So it does not require a separate power adapter to work. Here are the installation steps for NVR connections:


  • Use an Ethernet cable to connect the router and PoE NVR. Make sure the NVR can access the Internet.

  • Connect IP cameras to the PoE NVR directly by Ethernet cables. Enabled with PoE technology, the NVR can deliver power to the IP cameras.

  • Connect the NVR and a monitor or TV via a VGA or HDMI cable. Make sure the monitor or TV is connected via the correct input (e.g. VGA, HDMI 1, HDMI 2, etc.)

If all connections are made correctly, then the NVR is successfully connected with IP cameras. Figure 1 shows the whole connection. This NVR model is ideal for IP surveillance at homes and small businesses.

Option Two: Connecting NVR for IP Cameras With PoE Switch

NVR without Power over Ethernet means it has no Ethernet ports on the back panel, so it can not be connected to IP cameras directly, which requires an external PoE switch or a power adapter to provide power to each IP camera. Follow the steps below to finish the NVR connections.


  • Use Ethernet cables to connect the LAN port on PoE switch to the router, and connect the non-PoE NVR and the router. Make sure the PoE switch and NVR are in the same network.

  • Connect IP cameras to the RJ45 ports on the PoE switch by Ethernet cables. The PoE switch will provide power and video transmission as the NVR does.

  • Connect the NVR and a monitor or TV via a VGA or HDMI cable. Make sure the monitor or TV is connected via the correct input (e.g. VGA, HDMI 1, HDMI 2, etc.)

Note that users must add the cameras to the NVR to view the cameras and enable recording. Therefore, please follow the steps in the instruction manual attached with your NVR. Figure 2 shows the connection mode.

FAQs About NVR Setup for IP Cameras

Does NVR Require the Internet?

NVR can work without the Internet and continue to record and stream the video stream. However, without the Internet, users can not back up the videos on cloud storage, have no access to the recordings remotely, or even won't get push notifications or alerts in case of an intrusion.

Is NVR Better than DVR?

DVR (Digital Video Recorder) is a video processor that works with analog cameras and also functions as storage. The connection between an analog camera and DVR makes use of a coaxial cable. The recorder does not provide power to the cameras. Each camera connection requires a splitter that supplies power to enable cameras to function. Compared with NVR that works with IP cameras by Ethernet cables, DVR costs less. For people who are looking for a relatively straightforward security system, a DVR system will be sufficient, especially its property is already wired for a coaxial cable. For those who have remote monitor demands, or has high-resolution requirements, NVR with PoE functionality will be more suitable. So as for NVR vs DVR, choices should be made based on the actual needs.

How Far Can a PoE Camera Run?

The connection between an IP camera and NVR is achieved by Ethernet cables. Because of the signal attenuation, the max. transmission distance of the Ethernet cable is 100 meters. Thus, the max. distance that the camera can run from the NVR is also 100 meters. If users require to go beyond 100 meters, they can use an Ethernet extender that helps to extend the distance.
