Double detector

Introduction

In order to overcome the defects of a single technical detector, two different technical principles can be integrated together, and only the sensors of the two detection techniques detect human movement. The detector of the alarm is called a double detector. The common double detector in the market is multi-passive infrared, and there are also products such as infrared + air pressure detectors and audio + air pressure.

In order to further improve the performance of the detector, the detector of the microprocessor technology is added to the three-way detector on the basis of the double detector. A detector that adds another technique on the three-way detector into a four-way detector.

Characteristics

1, microwave and passive infrared method detection, and via fuzzy logic digital analysis, exclude disturbances that are unable to overcome in all kinds of ordinary detectors, only to the human body movement, Eliminate false positives, performance far exceeds a variety of infrared detectors that have no microwave function.

2, using the patented full range of precision temperature compensation, regardless of how the ambient temperature changes, the detection sensitivity is always consistent, there is no temperature dead zone (general detector at 32 ° C ~ 40 ° C, the sensitivity is greatly reduced) , Or in other temperature zones, it is easy to malfunction)

3, microwave detection is stable and reliable, anti-interference ability, maximum coverage range is wider, and can be viewed in viewpoint.

4, programmable functions, with maximum application flexibility.
