The main fundamentally important difference between an IP camera and an analog one is to convert the signal of the photosensitive matrix into a digital data transmission 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 video compression methods in IP cameras are MJPG, H.264, MPEG-4.

Home Security Camera records time-lapse video (one frame per second) and 
complete video only upon the occurrence specific events.
