Motion detectors are most often built into alarm kits. They are particularly useful for protecting a home from intrusions by giving warning in case of suspicious movement. These motion detectors operate according to a particular user manual and must be carefully installed.
How does the motion detector work?
The motion detector works through a infrared technique. It perceives the heat sources emitted by mammals, whether they are humans or animals, while ignoring obstacles such as objects or furniture. The motion detector is connected to an alarm system which can be triggered as soon as a movement is detected. The motion detector most often has a deterrent effect.
The motion detector can also be connected to a central surveillance, and the detection of an intrusion can be forwarded directly to a monitoring company who can then intervene.
Some motion detectors are equipped with dual-sensor for more efficiency. A remote control is often available to manage the alarm remotely, especially in case of false alarm.
Where to install a motion detector?
The location of a motion detector is important for its good efficiency. For all areas to be well covered, install motion detectors in the corners, in height so that their reach is not blocked by a wall or an obstacle.
The area covered by each motion detector is 10 to 12 meters. In large rooms, it is therefore advisable to install several. Do not forget to put them in the corridors. They can be supplemented by door and window opening detectors.
Motion detectors suitable for outdoor use also exist. They will protect your garden from intrusions. In any case, avoid installing motion detectors in direct sunlight as they are sensitive to temperature changes.
