Motion Detectors Work Like Magic

Motion detectors seem to work like magic, "seeing" people in your house without the use of hidden cameras. Three types of motion detectors are used in home security: infrared, ultrasonic and microwave.

  • Infrared motion detectors, which are the most common, sense body heat.
  • Motion detectors using ultrasonic waves send out pulses that measure moving objects.
  • With microwave motion detectors, the microwaves bounce off moving objects.

Ask your home security dealer about dual technology motion detectors, the gold standard of these protection devices. They use a combination of technologies to provide effective detection and fewer false alarms.
