Motion detectors are the most widely used sensors, but they are also responsible for most of the false positives. The reason is that usually only 1 PIR (passive infrared sensor) is installed and use outdoors requires special shielding against sun rays (infrared heat rays).

In order to significantly increase the security against false alarms, 2 independently working PIR sensors, a special analysis software and a pet immune protection are built into this DSP sensor (dual sensor protection). An alarm is only triggered if both PIR sensors detect a moving heat source (person) at the same time. Pets up to 15 kg are ignored.

The sensitivity of the PIR sensors is automatically adapted to the ambient temperature, which means that constant monitoring stability is achieved. In addition, this DSP sensor is built into 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 brackets on the housing are used for fastening.

The battery life is approx. 12-15 months with an average signal frequency.
The dual sensor motion detector will send its wireless signal up to 50m (150 ft) distance directly on your Andorid smartphone (iphone app is in development) and the DST connector.
