Closed-circuit television (CCTV) is the use
of video cameras to transmit a signal to a specific place, on a
limited set of monitors. *

Control for CCTV differs from broadcast television in that the signal is not
openly transmitted, though it may employ point to point wireless
links. CCTV is often used for surveillance in areas that may need
monitoring such as banks, casinos, airports, military installations,
and convenience stores.
In industrial plants, CCTV equipment may be used to observe parts of
a process from a central control room; when, for example, the
environment is not suitable for humans. CCTV systems may operate
continuously or only as required to monitor a particular event. A
more advanced form of CCTV, utilizing Digital Video Recorders (DVRs),
provides recording for possibly many years, with a variety of
quality and performance options and extra features (such as
motion-detection and email alerts).
Surveillance of the public using CCTV is particularly common in the
UK, where there are reportedly more cameras per person than in any
other country in the world. There and elsewhere, its increasing
use has triggered a debate about security versus privacy.
Closed-circuit digital photography (CCDP)
See also: Closed-circuit television camera
A development in the world of CCTV (October 2005) is in the use of
megapixel digital still cameras that can take 1600 x 1200 pixel
resolution images of the camera scene either on a time lapse or
motion detection basis. Images taken with a digital still camera
have higher resolution than those taken with a typical video camera.
Relatively low-cost digital still cameras can be used for CCTV
purposes, using CCDP software that use access controls for the camera from the PC.
Images of the camera scene are transferred automatically to a
computer every few seconds. Images may be monitored remotely if the
computer is connected to a network.
Combinations of PIR activated floodlights with 1.3Mpix and better
digital cameras are now appearing. They save the images to a flash
memory card which is inserted into a slot on the device. The flash
card can be removed for viewing on a computer if ever an incident
happens. They are not intended for live viewing, but are a very
simple and cheap "install and forget" approach to this issue.
Closed-circuit digital photography (CCDP) is more suited for
capturing and saving recorded photographs, whereas closed-circuit
television (CCTV) is more suitable for live monitoring purposes.
