A security alarm is essential for the security from unauthorized intrusion or trespassing in your premise and is vastly used residential, industrial, commercial, and government properties. The installation of security alarm system helps in detection of entry of intruder in the premise and this detection is done by a motion detection sensor that activates security alarm when some motion is detected, or the camera is intercepted by the presence of some physical object. This is very effective device for protection against break-in or protection against property damage.
How security alarm system works
Basically, a security alarm system has two core components – one or more sensors to detect unauthorized entry or intrusion, and an alerting sound device. It has premises control unit (PCU), and a panel which is alarm control panel (ACP). Two components are placed on different locations. Detection unit is placed within the range of protected area and alarming unit is placed in the open or accessible area and are connected to a power supply which has a battery-back up so that in case of electric supply disruption, the performance of security system is not affected. Some security systems also have smoke detectors that also detect fire apart from intrusion. This is complete integrated system that use cameras, sensors, vibration and sound device, buttons, indicator lights, and sometimes smoke detector that work in a sequence that follows from security risk detection to warning. These inter-connections between system scare burglars and a burglary is averted. Some advance security alarm systems use lasers and spotlights for more effective performance. Some security companies knoxville tn manufacture such advance security alarm systems.
Technology-based security alarm systems
Broadband signalling of alarm reporting has been made possible by growing positioning of voice over IP technology (VoIP). Some alarm installation sites don’t need to use conventional methods and alarm panel like components and this VoIP service is more trustworthy compared to the traditional system.
