Product Details:
Closed-circuit television (CCTV), also known as video surveillance, 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 (P2MP), or mesh wireless links. Though almost all video cameras fit this definition, the term is most often appied 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 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 detectors and email alerts). More recently, decentralized IP camerad, some equipped with megapixel sensors, support recording directly to the network attached storage devices, or internal flash for completely stand alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.
A growing branch in CCTV is internet protocol cameras (IP cameras). It is estimated that 2014 was the first year that IP cameras outsold analog cameras. IP cameras use the internet protocol used by most Local Area Networks (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras through any internet connection available through a computer or a phone, this is considered remote access. For professional or public infrastructure security applications, IP video is restricted to within a private netowrk or VPN, or can be recorded onto a remote server.
The camera unit is mounted inside a transparent doem which cen be tinted to obscure the camera position. Dome cameras come in a wide variety of forms. They can be analog or IP, fixed or mobile. PTZ domes can rotate (pan), incline (tilt) or focus closer on objects of interest (zoom).
