433Mhz Wireless Magnetic Door Detector Window Sensor for Wifi 3G Home Security System
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 Wifi alarm host to detect whether the doors, windows or drawers are illegally opened or moved. Once the un-permitted opening or movement is detected, it will send out signals to the host to achieve the goal of anti-theft alarm.
Please note that this is not a stand-alone device but can only be used as an accessory with compatible Home Security / Home Alarm systems
