PIR motion detectors and infrared beam sensors, wireless and wired.
PIR motion detectors sense the body heat of people moving in a room or area and trigger an alarm, light or camera recording. They are the most common sensors in alarm systems for homes, shops and offices. Pet-immune detectors ignore animals below a certain weight, which reduces false alarms. Infrared beam sensors create an invisible line between two units and trigger when the beam is broken, which is ideal for protecting fences, gates, driveways and perimeters. Check the detection range, angle, wireless frequency and compatibility with your alarm panel before ordering. Mount detectors away from heaters, windows and air conditioners to avoid false triggers.
