Public safety analysts are dependent on the good-quality display of video display that presents realistic imagery to aid accurate target identification and informed tactical decisions.
Increasingly, public safety responders are using high-quality video displays for:
Equipment: Video Decoder (player)
If a video has been compressed (or encoded), a decoder must be used to view (play) the video. There are many open-source video encoders/decoders, but there are also many proprietary systems. If a proprietary system is used, and a decoder (player) is not provided, the video cannot be viewed. A network video recorder (NVR), a digital video recorder (DVR), or a video cassette recorder (VCR) can perform both display and storage functions.
Selecting the proper display equipment is as important to the achievement of specific video application goals as selecting the appropriate camera equipment. Video display monitor might be either cathode ray tube (CRT) or liquid crystal display (LCD).
