Closed circuit television (CCTV) is the use of video
cameras to transmit a signal to a specific place, on a
limited set of monitors. It differs from broadcast
television in that signal is not openly transmitted,
though it may employ point to point (P2P), point to
multipoint, or mesh wireless links.
Burglar alarms have become standard equipment in
stores and other businesses, and they’re becoming
increasingly common in private homes as well. If
you’ve ever shopped for a home security system, then
you know there are a wide variety of options available.
