Appendix D: Recording Times - EverFocus PowerPlex EDR-920 Installation & Operation Manual

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).
