Network Video Recorders (NVR)
The IP Network recording devices, also called NVRs, support IP cameras: in particular, Setik and Dahua NVRs support exclusively Onvif cameras. Some Network Video Recorders have PoE support in order to supply the cameras without using a separate power source. Actually NVRs may support really high resolutions such as 4K and 12MPX while hybrid devices may rarely exceed resolutions greater than 2MPX. IP NVRs record the video signal coming from IP cameras and permit its view directly or remotely by means of CLOUD function (P2P). IP Network Video Recorders may support a high number of cameras depending on their processor: 4 channel Network recorders, 8 channel Network recorders, 16 channel Network recorders, 32 channel Network recorders, up to 64, 128 or even 256 channels.
