What are the different types of motion sensor systems?

Home safety systems generally have three types of motion sensor systems. Such systems most often use infrared technology, although microwave and dual technological systems are also available. Each type has its advantages and disadvantages, although everyone is also an effective way to protect home. Sensors use infrared light spectrum to measure the heat of objects that pass in front of them, and then compare it to the surrounding objects such as the wall. If the heat of the passing object is significantly higher than the objects behind it, the sensor goes out. Instead of covering a full room, infrared systems cover only scanned areas, although each sensor can be equipped with different lenses to cover a greater distance. The sensor then reads the frequency of the return wave. If the object moves, the sensor receives different microwaves than the ones that sent, which means the movement and postponement of the alarm. These types of systems cover a larger area than infrared sensors, are capable of penetrating the walls and reliablya width at longer distances. Despite this, they are the least popular option on the market due to their vulnerability to electric interference and their costs.

Dual Technology Systems use a combination of infrared and microwaves to provide the most complete coverage. The use of both forms of technology allows dual motion systems to reduce the incidence of false alarms by combining the range of microwave coverage and infrared technology of heat use. Although it is not as common as infrared motion sensors, the dual technological system quickly gains popularity between homeowners and businessness similarly.

Infrared, microwave and dual technological systems provide the same function, but each offers unique advantages and disadvantages. Each type of technology also provides several settings that allows the user to change sensitivity in cases where the home or building has a petATA or a large number of external animals that may unintentionally initiate alarm. The correct installation of any of these systems will help the house owner to improve security around his home.
