Products Introduction This Digital three-tech infrared detector is a high-performance detector with the latest technology in today’s security field. It is composed of a long-life microwave module, a high-precision passive infrared detection device and a fuzzy logic digital core. The shell is made of engineering nylon with beautiful shape. Poduction Details Combined detection of microwave and passive infrared, and digital analysis of fuzzy logic; Eliminate all kinds of interference that ordinary detectors cannot overcome, and only give an alarm for real human movement; Using full range precision temperature compensation; No matter how the ambient temperature changes, the detection sensitivity is always the same; There is no temperature dead zone (generally, the sensitivity of the detector is greatly reduced when the temperature is 32-40 degrees, or it is easy to misreport in other temperature zones); Microwave adaptive frequency modulation and linear propagation technology can effectively reduce interference from electric fans and hanging objects; Anti-jamming technology, multiple detectors can be installed in the same space without affecting each other, and even two detectors can be installed relative to each other.
