Intruder Alarm

​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.

​Boston is a port and market town in Lincolnshire, on the east coast of England, about 100 miles (160 km) north of London. It is the largest town of the wider Borough of Boston local government district. The town itself had a population of 35,124 at the 2001 census,[1] while the borough had a total population of 66,900, at the ONS mid-2015 estimates.[2] It is north of Greenwich on the Prime Meridian.

Boston's most notable landmark is St Botolph's Church ("The Stump"), the largest parish church in England,[3] visible for miles around from the flat lands of Lincolnshire. Residents of Boston are known as Bostonians. Emigrants from Boston named several other settlements around the world after the town, most notably Boston, Massachusetts, in the United States.
