How do DVR systems work?
A. DVR systems, which work completely digitally, sense analog images as digital ones, store them and define records by time and date information. Q. How big of a record can a DVR store? A. This value varies according to the image quality, recording values and the compression technique used. A camera that displays 5 screens per second would need 1.2 GB of storage space a day if the minimum image size is 3Kb.
