Analog CCTV Systems
Cameras on a modern analog CCTV system send their video images in the traditional base band format over coax or unshielded twisted pair (UTP) cabling back to a digital video recorder (DVR). Here, video is digitized and stored on hard drives.
Most modern DVRs are a network device, and as such can be accessed remotely from the LAN (local area network), or with the proper configuration, from across a WAN (wide area network) or the internet.
There are no tapes to change. Video is kept on hard drives, typically on a FIFO (first in first out) basis so there is always a rolling video archive. So, despite the fact that video is being transmitted from the cameras in an analog format, live and recorded video is still available over the network.
