Home motion detectors are essential security systems that provide straight-forward protection to your home. Home motion detectors work by triggering an alarm, turning on a light or automatically dialing your local police department whenever it detects motion once the motion detector is in its active mode. There are various types of home detectors that you can choose from, ranging from the active infrared motion detectors to vibration motion detectors. Below are the 5 types of home motion detectors and how they work.
Ultrasonic Home Motion Detectors
Ultrasonic home motion detectors are reliable and easy to install home motion detector system. Ultrasonic home motion detectors work by emitting sound at a specific frequency. When there is movement in the area where the ultrasonic home motion detector is directed, the detector will detect a disruption on the sound frequency and will then trigger an alarm. Ultrasonic home motion detectors are ideal for homes with automatic doors but can also be used in any type of doors in any area of your house.
Active Infrared Home Motion Detectors
Active Infrared home motion detectors work by emitting a low-level radiation in a specific area. When an intruder passes through the radiation field that the active motion sensor is emitting, the sensor will detect a change in the temperature of the radiation field caused by body heat. Once the active infrared home motion detector detects the temperature change in its radiation field, it will then trigger an alarm or automatically call your local police station.
Passive Infrared Home Motion Detectors
Instead of emitting a radiation field like what active infrared home motion detectors do, passive infrared home motion detectors emit infrared light to sense a change of temperature in its surrounding environment. Most passive infrared home motion detectors have a heat sensor and an infrared sensor that triggers an alarm whenever there is a disruption on the infrared beam or there is a change of temperature in the area where it is monitoring. Passive infrared home motion detectors are widely used by most homeowners for their reliability and cost-effectiveness.
Home Vibration Sensors
To detect unauthorized entry in your home, home vibration sensors look for the electrical field that any object emit including the human body. When a home vibration sensor detects an electrical field increase on the area where it is installed, it automatically triggers an alarm.
Continuous Wave Radar Home Motion Detectors
For a more advanced home motion sensor there is the continuous wave radar home motion detector that works in the same principle as the radars used by the military. This type of home motion sensor emits a burst of microwave signals which bounce off objects. In its active mode, a continuous wave radar home motion detector detects a disruption on the microwave signals that it is emitting such as a person walking, it will then trigger an alarm. This home motion sensor is very sensitive and costs more than any other type of home motion sensors available today.
