An intruder alarm security system is designed to detect unauthorised entry into your home or business. The most basic burglar alarms monitor a property for security breaches, such as the opening of a door or the breaking of a window. When movement is detected, a loud siren or silent alarm is triggered.
A basic intruder alarm system consists of a control panel, with rechargeable battery power backup and internal or external keypads, several interior and perimeter intrusion detectors, and one external sounder, at least.
An intruder alarm system can be classified as an hardwired, wireless, or an hybrid system. Wireless systems are used when there is not pre-wiring, operating at 433/868 MHz.
Most secure intruder alarm systems are hardwired systems, because wireless systems will use additional battery power and, even with Anti-jamming protection, still can be affected by radio-frequency interferences. Hybrid alarm systems allow simultaneously the installation of wireless and hardwired detectors, being the most versatile.
