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.
Skegness (/ˌskɛɡˈnɛs/ skeg-NESS) is a seaside town and civil parish in Lincolnshire, England. On the Lincolnshire coast of the North Sea, the town is 43 miles (69 km) east of Lincoln and 22 miles (35 km) north-east of Boston. With a population of 19,579, it is the largest settlement in the East Lindsey district; it also incorporates Winthorpe and Seacroft, and forms a larger built-up area with the resorts of Ingoldmells and Chapel St Leonards to the north. The town is on the A52 and A158 roads, connecting it with Boston and the East Midlands, and Lincoln respectively. Skegness railway station is on the Nottingham to Skegness (via Grantham) line.
The original Skegness was situated farther east at the mouth of The Wash. Its Norse name refers to a headland which sat near the settlement. By the 14th century, it was a locally important port for coastal trade. The natural sea defences which protected the harbour eroded in the later Middle Ages, and it was lost to the sea after a storm in the 1520s. Rebuilt along the new shoreline, early modern Skegness was a small fishing and farming village, but from the late 18th century members of the local gentry visited for holidays. The arrival of the railways in 1873 transformed it into a popular seaside resort. This was the intention of the 9th Earl of Scarbrough, who owned most of the land in the vicinity; he built the infrastructure of the town and laid out plots, which he leased to speculative developers. This new Skegness quickly became a popular destination for holiday-makers and day trippers from the East Midlands factory towns. By the interwar years the town was established as one of the most popular seaside resorts in Britain. The layout of the modern seafront dates to this time and holiday camps were built around the town, including the first Butlin's holiday resort which opened in Ingoldmells in 1936.
The package holiday abroad became an increasingly popular and affordable option for many British holiday-makers during the 1970s; this trend combined with declining industrial employment in the East Midlands to harm Skegness's visitor economy in the late 20th century. Nevertheless, the resort retains a loyal visitor base and has increasingly attracted people visiting for a short holiday alongside their trip abroad; tourism increased following the recession of 2007–09 owing to the resort's affordability. In 2011, the town was England's fourth most popular destination for UK residents, and in 2015 it received over 1.4 million visitors. It has a reputation as a traditional English seaside resort owing to its long, sandy beach and seafront attractions which include amusement arcades, eateries, Botton's fairground, the pier, nightclubs and bars. Other visitor attractions include Natureland Seal Sanctuary, a museum, an aquarium, a heritage railway, an annual carnival, a yearly arts festival, and Gibraltar Point nature reserve to the south of the town.
Despite the arrival of several manufacturing firms since the 1950s and Skegness's prominence as a local commercial centre, the tourism industry remains very important for the economy and employment. Its low wages and seasonal nature, along with the town's aging population, have contributed towards high levels of deprivation among the resident population. Residents are served by five state primary schools and a preparatory school, two state secondary schools (one of which is selective), several colleges, a community hospital, several churches and two local newspapers. The town is home to the divisional police headquarters, a magistrates court and a lifeboat station.
