Motion detectors are the most widely used sensors, but they are also responsible for the majority of false alarms. The reason is that usually only 1 PIR (passive infrared sensor) is installed and outdoor use requires special shielding against the sun’s rays (infrared heat rays).
In order to significantly increase false alarm security, this DSP sensor (dual sensor protection) has 2 independently working PIR sensors, special analysis software and pet immune protection installed. An alarm is only triggered if both PIR sensors detect a moving heat source (person) at the same time. Pets up to 15 KG will be ignored.
The sensitivity of the PIR sensors is automatically adjusted to the ambient temperature, thereby achieving consistent monitoring stability. In addition, this DSP sensor is installed in a weatherproof housing and can therefore be used outdoors. The two PIR sensors generate a beam-like sensor area, comparable to the function of a light barrier. These two sensor areas are mounted parallel to the floor at a height of 1.5 m, the sensors have a sensor range of 10-12 m.
The dual motion detector works with 2 x AA batteries, the weatherproof housing made of UV-resistant, black ABS plastic has an inconspicuous size of only 12 x 6 x 4 cm. The tabs on the housing are used for attachment.
The battery life is about 12-15 months with average signal frequency.
