About the Products
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 the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom
called “CCTV” but the use of video in distance education, where it is an important tool, is often so called.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when 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). gered a debate about security versus privacy.
About The Function & Application
As mentioned, CCTV is most commonly used for surveillance. Most major institutions, such as banks or schools, have CCTV networks to reduce the need for human security. Prisons use CCTV for monitoring behavior from a central location in addition to regular patrols.
Video taken with CCTV can be recorded and reviewed later. CCTV has other practical applications beyond surveillance and CCTV networks don’t necessarily feature security cameras. Any kind of on-site video technology uses CCTV, such as a video conference that is only accessible for a select audience.
While CCTV camera systems certainly keep watch over prison inmates and possible bank heists, they also aid in more positive efforts. The ability to constantly monitor an area aids in the care of elderly patients, providing medical intervention or assistance as soon as a problem arises. Caregivers keep an eye on playing children through the system, and wildlife researchers are able to document and study the behaviors and patterns of elusive animals.
When paired with a home alarm system, the CCTV surveillance cameras act as a trigger to sound the alarm if it detects suspicious or aggressive behavior. A person walking along the sidewalk in front of the house would not arouse suspicion, but someone sneaking through the bushes or attempting to open a locked window or door would. This sudden alarm, and the threat of getting caught by curious neighbors or summoned police, usually encourages a potential burglar to seek easier pickings.
Sometimes the presence of a security system cannot prevent a crime. In this instance, the recorded images are turned over to the police, who study them in an attempt to identify the wrongdoer, or gather clues to his identity. This photo and video evidence also aids in prosecution of the criminal once caught.
