Security Systems

Security systems are widely available for home and industrial use. The most widely available form of home security is the burglar alarm, with is often see mounted on the front of buildings to warn potential intruders that the building is protected. Security systems such as these will often implement infra-red motion sensors positioned in rooms so that any movement, when the system is set, will be detected thus triggering the alarm alerting the occupants that there is an intruder. Modern burglar alarms often have a relay to a local police force so that the authorities are instantly informed if the alarm is triggered.

Another device which is often used in conjunction with other aspects of security systems is CCTV, which stands for closed circuit television, a series of camera used for surveillance of a particular area. These are often used as a method of crime prevention as the presence of the camera will often deter an individual from committing a crime. It is for this reason that CCTV cameras are often located in areas when crime is likely to occur, such as in shops or around car parks. In the instances where the presence of cameras is enough to deter then the footage that they record can be used as evidence in court.
