IP / Network Security Camera System Design
In the IP world, each network camera captures an analog image but immediately converts
it to digital inside the camera. Some digital processing can happen right at the
camera, such as compression and motion detection. The digital video stream is then
broadcast over the local area network (LAN) using Ethernet (CAT5 or CAT6) cable.
Power is supplied to the cameras through the Ethernet cable via Power-
A Network Video Recorder (NVR) performs the same function as its DVR cousin in the analog world. It captures each camera’s signal, compresses, and records it. The main difference is that the video feeds are digital (and much higher resolution) and not analog. Software built into the NVR provides features such as intelligent search and zoom, etc. The NVR combines the video streams from the cameras and handles the broadcast over the LAN and internet for local and remote viewing.
