NVR/DVR/XVR Diffrences

What Are DVR, XVR/HVR, and NVR?

What is DVR

This is a Digital Video Recorder that records videos in digital format that can be saved on a disk drive, SSD, SD memory card, or USB flash drive. It is like a basic VCR that uses hard drives instead of videotapes. It can pause live TV in real-time by recording the current show.

For CCTV technology, the DVR converts analogue signals to digital in a compressed format. Without the DVR, IP cameras can work independently, the same way a security camera will work with SD cards. 

What is NVR

This is a Network Video Recorder. It works, like a DVR, by recording videos in a digital format onto USB drives and SD memory cards. It does this by using its software program and its video quality is better than the DVR.

Since Ethernet cables carry audio signals, cameras with microphones can record audio signals to the NVR. The major difference between the NVR and DVR lies in the way they process video. NVRs are mostly used with IP Cameras while DVRs are used in connection with analogue cameras. Our range of NVR's can handle AI analytics like face and human detection, tripwire etc.

What is XVR/HVR

This is a Super Digital Video Recorder. In simple terms, this is DVR of higher specifications.  This type of DVR can handle various cameras, like AHD, TVI, CVI, Analog and IP cameras, at various resolutions, as well as with smart two way communication between the cameras and DVR.  Our XVR systems can handle AI analytics like Human and Face Detection
