What are codecs?

Codecs is a device or program that compresses data to enable faster transmission and decompresses received data. In simple terms, it reduces the size of the file.

Does file size matter?

Frankly speaking, it depends. Majority of CCTV system has a loop feature, it deletes the oldest recording to be able to record a new one when there is no more storage. 

I  will explain the most commonly used resolution by companies or housing properties.

Resolution and Codecs will affect how much storage your CCTV will use to record.
