Outstanding features:
A. Compared with ordinary dual-element infrared detectors and curtain detectors, it has stronger false alarm prevention ability and better detection performance. Ken has the ability to identify the direction of invasion. The alarm will not be triggered when the user invades the security area from the inside out, but only when the user invades from the outside illegally, which greatly facilitates the user to move in the fortified security area without triggering the alarm system.
B. The patented full-range accurate temperature compensation and airflow prevention technology are adopted, so that the detection sensitivity is consistent no matter how the ambient temperature changes, and there is no temperature dead zone (generally, the detector sensitivity is greatly reduced at 32 ~40, or it is easy to misreport in other temperature zones), especially suitable for preventing the whole wall analysis window, large balcony, corridor, etc.
C. Pure wireless structure, fully built-in power supply, wireless signal transmission, and extremely convenient installation.
D. Ultra-energy-saving design+large-capacity battery, which lasts longer than other wireless infrared detectors.
E. Built-in expansion slot is compatible with various wireless hosts.
