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.
Rhyl (/rɪl/; Welsh: Y Rhyl, pronounced [ə ˈr̥ɨl]) is a seaside resort and community in the Welsh county of Denbighshire. It lies within the historic boundaries of Flintshire, on the north-east coast of Wales at the mouth of the River Clwyd (Welsh: Afon Clwyd). To the west is the suburb of Kinmel Bay and the resort of Towyn beyond, to the east Prestatyn, and to the south Rhuddlan. At the 2011 Census, Rhyl had a population of 25,149, with Rhyl-Kinmel Bay having 31,229. The Abergele–Rhyl–Prestatyn conurbation numbers over 60,000. Once an elegant Victorian resort, an influx from Liverpool and Manchester after the Second World War changed the town's face. It had declined sharply by 1990, but has since been improved by major regeneration investments. Several million pounds of European Union funding to the Welsh Government has gone on developing the seafront.
