Another good article at the same site compares the analogue components of traditional CCTV with IP CCTV:
A video surveillance system consists of four components – Camera, recording, monitor and video network. The CCTV/DVR systems which were employed earlier used the CCD Cameras to record the video which is converted in to analog form for transmission over the co-axial cables and then again digitized in the DVR (Digital Video Recorder) for compression and recording. So, this multiple conversion system (just to carry the video signals over the Co-axial cable) was quite inefficient especially when the digital video signal was converted in to analog signal then back again to digital signal. That’s where the IP Surveillance system comes in to the picture which enables the entire process to be digitized completely. We will take a look at how it is done at the individual component level.
