Exactly how does a CCTV DVR function?

A CCTV digital video recorder (or “DVR” for short) is mainly a PC which saves security video images into a hard drive. A lot of security cameras in use now capture an analog image. The DVR transforms the analog signal to digital after which compresses it.
Numerous video cameras may be connected to one DVR. DVRs typically come with 4, 8, 16, or 32 camera inputs. The DVR will allow you to view all of these images at the same time or individually, and all of the video is saved to the hard disk. Added switches, quads, or multiplexors aren't required.
