FAQ

A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive. A DVR is basically a VCR that uses a hard drive instead of video tapes. It can be used to record, save, and play back television programs. Unlike a VCR, however, a DVR can also pause live TV by recording the current show in real time.

The television signal comes into the DVR's built-in tuner through antenna, cable or satellite. If the signal comes from antenna or cable, it goes into an MPEG-2 encoder, which converts the data from analog to digital (MPEG-2, by the way, is the compression standard used to fit information onto a DVD).

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

An Internet Protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed-circuit television (CCTV)cameras, can send and receive data via a computer network and the Internet.

An AV drive (audio-visual drive) is a hard disk drive which is designed specifically for audio and video purposes. They were used in the late 1990s for sustained media transfers; they delayed thermal recalibration so it would not interfere with the transfer.
