Motion detectors detect any sort of motion. When connected to a transformer the motion gets translated into an electric signal. This device may be connected to a burglar alarm that immediately alerts the home-owner of any motion that gets detected.
There are three types of sensors:
1. passive infrared sensors
2. ultrasonic active sensors
3. microwave active sensors
Most motion detectors use a combination of different technologies. These dual-technology detectors benefit each other to reduce complications of false alarms. Motion detectors offer feelings of protection and security. Most people find them suitable for
- driveway alarms
- yard alarms
- burglar alarms
- door announcers
Motion detectors make a safe path to welcome you back home, deterring would-be-intruders. When lights are triggered by motion this gives the impression that someone is home and able to see the burglar. Infrared motion detectors placed in crucial areas of the house can detect any burglars and alert the homeowner or police.
Motion detectors have the advantages of being:
3. easy to install
4. no monthly monitoring fees
Studies on crime prevention indicate that houses set up with motion detectors do help enhance security. They are a great way to get all the benefits of having a watchdog without the hassle of owning a dog.
