What are codecs and how do they work in video surveillance?

Codec is an amalgam of the words compression & decompression. Compression is the process of reducing bandwidth and storage consumption.

Because each frame of recorded video contains many of the pixels that were in the previous frame, codecs compress video by only recording the pixels that changed between frames thereby reducing bandwidth consumption and processing power.
