What is the difference between an IP CCTV camera and an analog one?
The main fundamentally important difference between an IP camera and an analog one is the conversion of the signal of the photosensitive matrix into a digital data stream. This is done by the built-in hardware encoder. The main feature of the analog signal is that it is transmitted strictly from the matrix to the receiver, for example, from the antenna to the TV. No feedback. The main methods of video compression in IP cameras are MJPG, H.264, MPEG-4. There are several representatives of IP cameras that transmit video without preliminary compression.
