Wireless security systems can be easily controllable through a wireless remote or a touch tone phone from any place. Here main components of the laser security system are infrared motion sensors and a basic alarm unit. It works based on heat detection from a person’s body in case of any security fault. Based on this alarm unit is triggered. The system alerts the security monitoring person and the local law enforcement body if required. At the same time a high pitched sound also sirens. There are two types of laser beams are available, green and infrared modules. System via an infrared module will be not visible. Another beam like green would be visible to the naked eye and serve as a deterrent purpose.
