A DVR system consists of a set of closed-circuit cameras that are all connected to a DVR device or a computer capable of digital recording. Many people upgrade existing analog closed-circuit television (CCTV) systems to these digital DVR systems. You can have this type of system professionally installed.
The cameras will record digital videos onto the hard drive of the DVR or computer. Your main limitation will be how much space you have on your hard drive. This will also be affected by the quality at which you are recording your video footage: the higher number of frames per second, the larger the files. When you run out of space, your DVR will stop recording unless it’s programmed to overwrite old data once it reaches capacity.
