DVRS ARE TYPICALLY USED WITH ANALOG CAMERAS. ANALOG CAMERAS TRANSMIT A RAW VIDEO SIGNAL TO THE DVR OVER COAXIAL CABLES.
THE DVR THEN CONVERTS THE
ANALOG SIGNAL TO A DIGITAL FORMAT THAT CAN BE STORED AND VIEWED REMOTELY.
NVRS ARE TYPICALLY USED WITH IP CAMERAS. IP CAMERAS ENCODE AND PROCESS VIDEO DATA AT THE CAMERA LEVEL, BEFORE TRANSMITTING IT TO THE NVR OVER AN ETHERNET CABLE OR WIRELESSLY.
THE NVR THEN STORES AND VIEWS THE VIDEO DATA.
