433MHz Wireless Door Window Detector and Sensor

The appearance is unprecedentedly small and delicate.
The antenna is built-in which is a new design.
The front cover can be opened to replace the battery by sliding.
It works with the alarm host to detect whether the doors, windows or drawers are illegally opened or moved.
Once the unpermitted opening or move is detected, it will send out signals to the host to achieve the goal of an anti-theft alarm.
