surveillanceelectronic surveillancestakeout
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, stores, and other areas where security is needed.
This can include observation from a distance by means of electronic equipment (such as closed-circuit television (CCTV) cameras) or interception of electronically transmitted information (such as Internet traffic or phone calls).

IP camera

More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
An Internet Protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed-circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet.

Though Videotelephony is seldom called 'CCTV' one exception is the use of video in distance education, where it is an important tool.
Such an antecedent usually consisted of two closed-circuit television systems connected via coax cable or radio.


pay-per-viewpay per viewPPV
Closed-circuit television was used for professional boxing, as a form of pay-per-view theatre television.
The earliest form of pay-per-view was closed-circuit television, also known as theatre television, where professional boxing telecasts were broadcast live to a select number of venues, mostly theaters, where viewers paid for tickets to watch the fight live.

Cameras have also been installed on public transport in the hope of deterring crime, and in mobile police surveillance vehicles, often with automatic number plate recognition, and a network of APNI-linked cameras is used to manage London's congestion charging zone.
It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task.

BournemouthBournemouth, EnglandBournemouth Borough Council
Experiments in the UK during the 1970s and 1980s, including outdoor CCTV in Bournemouth in 1985, led to several larger trial programs later that decade.
The Bournemouth International Centre (BIC), a large conference and exhibition centre, was constructed near the seafront in 1984, and in the following year Bournemouth became the first town in the United Kingdom to introduce and use CCTV cameras for public street-based surveillance.

Video camera

video cameravideo camerasVideo
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.
A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required.


Furthermore, they argue that CCTV displaces crime, rather than reducing it. Critics often dub CCTV as "Big Brother surveillance", a reference to George Orwell's novel Nineteen Eighty-Four, which featured a two-way telescreen in every home through which The Party would monitor the populace.
Telescreens are devices which operate as both televisions, security cameras and microphones.

Security guard

Nonetheless, private sector personnel in the UK who operate or monitor CCTV devices or systems are considered security guards and have been made subject to state licensing.
Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking (either directly, through patrols, or indirectly, by monitoring alarm systems or video surveillance cameras) for signs of crime or other hazards (such as a fire), taking action to minimize damage (such as warning and escorting trespassers off property), and reporting any incidents to their clients and emergency services (such as the police or paramedics), as appropriate.

The first CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Nazi Germany in 1942, for observing the launch of V-2 rockets.
The same year Siemens acquired Photo-Scan (UK, CCTV systems), US Filter Corporation (water and Waste Water Treatment Technologies/ Solutions, acquired from Veolia), Hunstville Electronics Corporation (automobile electronics, acquired from Chrysler), and Chantry Networks (WLAN equipment).

With the addition of fixed cameras for the active traffic management system, the number of cameras on the Highways Agency's CCTV network is likely to increase significantly over the next few years.
Operators can also monitor 150 CCTV cameras along the route and can control both the speed limits and information signs.

Artificial intelligence for video surveillance

Artificial intelligence for video surveillance utilizes computer software programs that analyze the images from video surveillance cameras in order to recognize humans, vehicles or objects.

TV Network Protocol

Television Network Protocol
It uses a network protocol called Television Network Protocol to allow access to many more cameras than each individual system owner could afford to run and maintain.
The TV Network Protocol or TVNP as it is more commonly referred to is an open network protocol developed to enable CCTV systems from any manufacturer to be integrated into an existing CCTV network.

Physical security

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).
Digital video recorders configured for physical security applications record video signals from closed-circuit television cameras for detection and documentation purposes.

Proprietary DVR

CCTV systems are used for the detection and recording of crime, but the analysts and law enforcement personnel who are required to obtain and process video recorded with proprietary DVRs may face problems using the proprietary format.
