A burglar alarm /intruder alarm is a proven deterrent against burglary and crime. There are two main types of burglar alarm, these are:
Bells only: - These systems rely on sounders to both deter the burglar and also warn neighbours of the intrusion. A system will normally have 1 external sounder as a minimum, this can be added to by having an internal siren as an extra deterrent inside the property, an additional decoy box on other exterior elevations to provide extra visual deterrent outside or an extra external sounder could also be used.
Monitored Systems: - These systems have all the features of the ‘bells only’ system with the addition of being monitored by a central station via you home Internet Connection, telephone line or GPRS link. When the alarm is triggered it sends a signal to the central station, which then notify the key holders and police of the alarm. These systems are a requirement of some insurance policies, normally where this is the case it is also a requirement that an alarm installation company that is a member of an approved installations organisation installs them.
