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 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"). 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. 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.[needs update] About 65% of these cameras are installed in Asia. The growth of CCTV has been slowing in recent years.[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.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.
Reading (/ˈrɛdɪŋ/ (audio speaker iconlisten) RED-ing) is a historic large market town in Berkshire, England, in the Thames Valley at the confluence of the rivers Thames and Kennet. It is on the Great Western Main Line railway and the M4 motorway, 40 miles (64 km) east of Swindon, 25 miles (40 km) south of Oxford, 40 miles (64 km) west of London, 15 miles (24 km) north of Basingstoke, 13 miles (21 km) southwest of Maidenhead and 15 miles (24 km) east of Newbury. Reading is a major commercial centre, especially for information technology and insurance. It is also a regional retail centre, serving a large area of the Thames Valley, and home to the University of Reading. Every year it hosts the Reading Festival, one of England's biggest music festivals. Among its sports teams are Reading Football Club and Reading Hockey Club, and over 15,000 runners annually compete in the Reading Half Marathon.
Reading dates from the 8th century. It was an important trading and ecclesiastical centre in the Middle Ages, the site of Reading Abbey, one of the largest and richest monasteries of medieval England with strong royal connections, of which the 12th-century abbey gateway and significant ancient ruins remain. By 1525, Reading was the largest town in Berkshire, and tenth in England for taxable wealth. The town was seriously affected by the English Civil War, with a major siege and loss of trade, but played a pivotal role in the Glorious Revolution, whose only significant military action was fought on its streets. The 18th century saw the beginning of a major ironworks in the town and the growth of the brewing trade for which Reading was to become famous. The 19th century saw the coming of the Great Western Railway and the development of the town's brewing, baking and seed growing businesses, and the town grew rapidly as a manufacturing centre.
