What is DVR?
A DVR (Digital Video Recorder) is a video recording device that receives analog signals from CCTV and converts them to digital via coaxial cable. It can be used for simple and cost-effective security systems.
What is NVR?
NVR (Network Video Recorder) is a digital video recording device for IP (Internet Protocol) cameras. IP cameras already directly produce video in digital format and support higher video quality, including Full HD and 4K resolutions.
NVR acts as a place to store and manage data from IP CCTV. Data from IP cameras is sent over a LAN or WiFi network, making NVRs more flexible in terms of installation and access. The simplicity of the network connection makes the video on the NVR remotely accessible via the internet.
