Motion Detectors


Motion detectors offer different #technology options depending on necessity. They are used as intrusion detection #devices and #work in #combination with #alarm systems. Infrared motion detectors observe changes in infrared #light patterns. #Heat-based motion detectors #sense changes in heat levels. Wave pattern motion #detectors use #ultrasonic or #microwave #frequencies that monitor changes in reflected patterns. Capacitance motion detectors monitor for changes in #electrical or #magnetic #fields. #Photoelectric motion detectors look for changes in #light and are used in #rooms that have little to no light. Passive #audio motion detectors listen for unusual #sounds.

Motion detectors may be either #hardwired or #wireless and run by #batteries, so are easily added to an existing security system. As soon as it detects movement, it will #trigger the alarm. Motion detectors are an essential weapon in security field. Its biggest benefit is providing further security against #burglars/theft. If your alarm system is somehow breached without alerting you to an open #door or #window, your motion detectors will sense your intruder and sound the alarm. This gives you time to reach #safety while your alarm company calls for #police assistance.
