Motion sensor: what is it for?

With a motion sensor, or motion detector, it is possible to monitor an area inside the house or in outdoor spaces, including the garden and courtyard. Integrated into multiple surveillance systems or independent of them, the motion detector is an essential security device to defend against thieves and protect your property from intrusions while you are away electricians in Coeur d’Alene.

The main advantage consists in the constant surveillance of the defined area within a certain range of action and in the consequent automatic activation of the various accessories connected (from the light to the alarm) when a movement is signaled. But how exactly do these products work? And why are they now an integral part of home (and not just home) security alarms? We try to answer these and other questions by analyzing the salient points to be taken into consideration.

The motion sensor: a reliable presence detector

First of all, it must be said that the motion sensor is a mature product, already present in many private and corporate security systems. The reason? Thanks to its wireless motion sensors, this accessory is able to recognize the presence of a solid body via infrared and by detecting the temperature: if it is configured to trigger an alarm, the detector will go into action as soon as the conditions for which it has been programmed, i.e. as soon as there is a stranger who is intercepted by the sensor itself (typically while the house remains unattended). It is difficult to evade this type of automatic surveillance, to do so you would have to be invisible or not produce heat with your body! Not only that, because the most advanced motion sensors, called smart sensors or intelligent sensors, they can provide more elaborate information, the result of the analysis of what is being accessed and integration with other equally smart devices such as the alarm siren, surveillance cameras (perhaps with facial and biometric recognition) and much more. Maximum reliability therefore, for a detection technology that always lives up to expectations in every residential, commercial and industrial context. Let’s now take a step forward and see what infrared detectors and sensors.
