What is the movement detector switch?

Motion detector switch is a device used for home security. After installing these sensors, detect movement in the area, usually less than 100 feet. Movement sensors usually trigger loud sounds or light to go out, alert the owners of a house of a potential thief and make thieves. The motion sensor can also be connected to the burglary alarm that is signaled by a security company or offers automatically call pre -programmed phone numbers for assistance.

Generally, the movement detector switch uses infrared, sound or microwave sensors to detect movement. Infrared switches measure infrared energy or heat radiation and are lowered when the thermal signal is detected in the range of the human body temperature. Motion ultrasonic detectors use sound waves to detect movement. If movement is detected, the sound wave formula is disturbed and alarm is signaled. Motion -based motion detectors can also use passive sensors and to be triggered by a glosel break.Microwave sensors reflect microwave signals from objects and then measure the length of the waves for movement detection; These sensors can often penetrate the walls to detect movement.

There are disadvantages for the use of infrared, ultrasonic and microwave sensors. Infrared switches usually have a limited range of movement and can sometimes be buried with housewives. Sound wave sensors could randomly induced sounds from animals passing or ringing phones, while microwave sensors can be exposed to moving from objects blowing into the wind and cannot penetrate metal. The detector of the movement detector of duel-technology can be used to reduce the likelihood of false positive. Duel-technology movement detectors use infrared and microwave technology to eliminate these gaps in the system.

Motion detector lights are usually used around perimeterTo illuminate dark areas in large or side yards, as well as around the verand, driveway and garages. These lights make it difficult to slip into the house without being detected. Motion detector warning systems can also turn on the house owners so that the car that gets into the driveway or draws attention to the presence of someone approaching the front door before the alarm rings. Inside the house, these sensors are usually placed along the inner doors, windows, stairs and in the hallway - an area where the intruder is likely to pass.

For maintenance -free solution, there is another option to consider. Solar safety lights do not require any wires to be installed and are powered by solar energy that makes these lights useful even if the power appears. The solar movement detector switch can usually be applied in the interior or exterior of the house.

To increase the overall safety of the household many individuals use the movement detector switchTogether with the came. These motion -based cameras can be placed along the perimeter of the building, as well as near the pool, playgrounds and entrance doors to provide home supervision. Because these devices only record when the movement is detected, they can usually store storage space for data.
