NVR Full Form and Meaning
NVR stands for Network Video Recorder, which records videos directly from the network using Cat5 or Cat6 Ethernet cables with RJ45 plugs. The NVR system is used with IP (Internet Protocol) cameras.
There are two types of network video recorders: PoE NVRs, which generally have Ethernet ports to connect PoE cameras, and WiFi NVRs, which have no camera ports because they connect to WiFi cameras wirelessly.

DVR stands for Digital Video Recorder, which means that DVR recorders process uncompressed videos with coaxial cables and compress the videos to digital signals before sending them out. The DVR system works with analog cameras.
What is HVR?
HVR (Hybrid Video Recorder) is a combination of DVR and NVR systems, which can work with both analog cameras and IP cameras. The HVR system is often priced much higher than the DVR or NVR systems, usually over $1000, which may be beyond many consumers’ budgets.
DVR and NVR systems typically come in 4-channel, 8-channel, and 16-channel options. The channel count indicates how many cameras can be connected to the DVR or NVR system. For instance, a 16 channel DVR would enable you to have up to 16 cameras connected to the system.
