First of all, it should be noted that all our detectors are passive. That is, they do not emit anything, but only read information.
Linear detectors are used to protect the perimeter. Their detection zone is a beam or cone with a tip in the detector sensor.
However, due to the fact that the detection area of the emitter is a cone, a linear emitter can protect not only the perimeter, but also some objects entirely, or, for example, the entrance to the room, if you install the detector opposite the entrance door.
Another important feature of the linear emitter is the large length of the detection zone - up to 50-70 m. Volumetric detectors cannot boast of such an extended detection zone (it is only 8-10 m), but the cone of their detection zone has a much greater divergence. Therefore, such detectors are effective indoors, or for protecting small objects or small territories.
All the detectors described above operate in the infrared detection spectrum. That is, they monitor temperature changes in the detection area. However, the use of the infrared spectrum as an observation medium is not always suitable for solving the tasks of protecting objects.
For example, if the object is a car that is parked outside in the summer and is heating up, then the object of observation is too hot, which means it is bright in infrared light, so the object of observation will illuminate the entire detection area. Another example is the metal room of a transformer substation, which also heats up quite strongly in summer and the detection area of the internal volume for the infrared detector is likely to be illuminated.
A detector with a vibration detection principle is suitable for solving such tasks of protecting objects. Such a detector reacts to a mechanical impact on an object (break-in, damage, shock).
To eliminate false alarms in all our detectors, we have developed a unique mathematical apparatus and sensitivity adjustment.
