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.
Great Yarmouth, often called Yarmouth, is a seaside resort and minster town in Norfolk, England, straddling the River Yare, some 20 miles (30 km) east of Norwich. A population of 38,693 in the 2011 Census made it Norfolk's third most populous place. Its fishing industry, mainly for herring, fell steeply after the mid-20th century and has all but vanished. North Sea oil from the 1960s brought an oil-rig supply industry that now services offshore natural gas rigs. More recent offshore wind power and other renewable energy have created further support services. Yarmouth has been a seaside resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Tourism was boosted when a railway opened in 1844, which gave visitors easier, cheaper access and triggered some settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth was a booming resort, with a promenade, pubs, trams, fish-and-chip shops and theatres, and the Pleasure Beach, the Sea Life Centre, the Hippodrome Circus and the Time and Tide Museum, and a surviving Victorian seaside Winter Garden in cast iron and glass.
