This type of system uses a laser or series of lasers to create a sensor alarm circuit to protect your family and your area. Lasers are different from other types of light because they create a narrow line of light (like a laser pointer) whereas others, like flashlights, tend to spread it out. The laser security alarm circuit utilizes laser sensors for intruder detection. The main components of the laser security alarm circuit are infrared motion sensors and an alarm unit. It works by heat detection radiating from a person’s body. The circuit uses laser light and gets activated whenever any person crosses it.
