Average recording times, based on 100GB harddisk capacity.
Using the VBR (Variable Bit Rate) method, the storage requirement per image depends
on the image's colour and contrast content and captured motion.
The following calculations represent sample values for continuous recording. Actually
achieved values may differ and can be calculated by means of test recordings if required.
The value IMAGES/S refers to the total DVR recording rate (all installed cameras).
