​Closed-circuit television (CCTV), also known as video surveillance,[1][2] 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 wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV"[3][4]).

Surveillance of the public using CCTV is common in many areas around the world. Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in public.[5][6][7]

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, especially if the environments observed are dangerous or inaccessible to humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, using 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). More recently, decentralized IP cameras, perhaps equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.

By one estimate, there will be approximately 1 billion surveillance cameras in use worldwide by 2021.[8][needs update] About 65% of these cameras are installed in Asia. The growth of CCTV has been slowing in recent years.[9][unreliable source?] The deployment of this technology has facilitated significant growth in state surveillance, a substantial rise in the methods of advanced social monitoring and control, and a host of crime prevention measures throughout the world.[10]

A security alarm is a system designed to detect intrusions, such as unauthorized entry, into a building or other areas, such as a home or school. Security alarms protect against burglary (theft) or property damage, as well as against intruders. Examples include personal systems, neighborhood security alerts, car alarms, and prison alarms.

Some alarm systems serve a single purpose of burglary protection; combination systems provide fire and intrusion protection. Intrusion-alarm systems are combined with closed-circuit television surveillance (CCTV) systems to record intruders' activities and interface to access control systems for electrically locked doors. There are many types of security systems. Homeowners typically have small, self-contained noisemakers. These devices can also be complicated, multirole systems with computer monitoring and control. It may even include a two-way voice which allows communication between the panel and monitoring station.

​Romford is a large town in east London and the administrative centre of the London Borough of Havering. It is located 14.1 miles (23 kilometres) northeast of Charing Cross and is one of the major metropolitan centres identified in the London Plan.[2] Historically, Romford was a market town in the county of Essex, and formed the administrative centre of the liberty of Havering before that liberty was dissolved in 1892.[3][4] Good road links to London and the opening of the railway station in 1839 were key to the development of the town.[3] The economic history of Romford is characterised by a shift from agriculture to light industry and then to retail and commerce.[3] As part of the suburban growth of London throughout the 20th century, Romford significantly expanded and increased in population, becoming a municipal borough in 1937 and was incorporated into Greater London in 1965.[5][6][7] Today, it is one of the largest commercial, retail, entertainment and leisure districts in London and has a well-developed night-time economy as well.[8][9] Its population, as of 2011, was 122,854.[10]
