Most of the NVRs from CCTV Camera World utilize plug-and-play IP camera technology by offering built-in PoE ports. This allows a user to connect an IP camera to a NVR using only a single network cable.

Some of our NVR models, however, are designed without built-in PoE ports, or have a lesser number of PoE ports than total channels supported. For example, we have 16 Camera NVRs that offer eight built-in PoE ports. To utilize the remaining eight channels, you need to fetch the eight video streams over the network. This is also the case for Tribrid DVRs and XVRs that don't have any built-in PoE ports but still have the ability to stream and record IP cameras. This guide provides the steps necessary to change the IP address of IP cameras that are deployed on a network using a PoE switch external to the NVR.

Recording IP camera video feeds over a network (LAN) can be accomplished by using the following hardware:

Once you have an IP camera connected to a PoE switch, and that PoE switch and your NVR are connected to the same router, then they will be on the same LAN. In order for your DVR/NVR to communicate with the IP cameras you need to put the DVR/NVR on the same network as the cameras. They need to share the same IP address scheme. Depending on the IP address of your router, usually it is 192.168.1.X where X is a unique number assigned for each device on the network. To assign each camera a unique IP address that is compatible with your LAN, you can use the graphical user interface (GUI) of your DVR/NVR to quickly set the IP address of each camera as shown in the video tutorial below.

Since all new IP cameras we sell come with a static IP address of, it is important to note that you should configure each camera one at a time. Connect one new camera to a PoE switch and configure its IP address before connecting the next.

With our recorders, you can access the DVR/NVR's GUI interface directly using a monitor and mouse. Pull up the device registration page to see all devices on the network, such as IP cameras, NVRs, or DVRs, and their respective IP addresses. You can easily configure each device to a different IP address by selecting the device and clicking "Modify IP."
