A: Products
1. Wireless door magnetic sensor is a monitor and commonly used device in the security, safety and protection system, work is very reliable, compact, to work particularly by wireless, so very easy to install and use, and flexible.
2. Wireless Vibration Detector with vibration, touch, mobile comprehensive survey of principles. Once the vibration, automatic transmission signals to the host, call the police. 24-hour to protecte for avoiding to attempts into the protection of doors, windows or roof and so on by violence (drill, combat, saw, etc.).
3. Commonly used: windows and doors, safes, vault, vault door, automatic teller machines, night library / night safes, wall, roof, equipment, file cabinets, doors and so reduce electrical applications. Induction of high-quality components to ensure the life and performance. Long life, cost-effective. Compatibility

C: the working principle
Door magne have two parts .a wireless transmitter module and the magnetic block, the wireless transmitter module with two arrows have a "steel reed pipe" components, after the magnet and steel spring tube to keep a distance of 1.5 centimeter, the steel reed pipe in a disconnected state, once the magnet and steel spring tube separation distance of more than 1.5 cm, the steel spring tube will be closed, causing a short circuit, while warning light is launched to the host alarm signal.
