Abstract: A burglarproof device for vehicle comprises a main body and at least one mobile communication device is disclosed. The main body has a control circuit connecting to detection units, camera units, audio module, and wireless communication and GPRS module. The mobile communication device has APP program for receiving the transmitted signal of the main body and controlling the function of the APP program; wherein the wireless communication and GPRS module store at least one series of number dedicated to the mobile communication device; wherein the detection unit drives the camera unit to record a video, the control circuit collects the video and translates the format of the video, and then the wireless communication and GPRS module dials the series of number of the mobile communication device when the stealing is occurred.

Abstract: A disaster prevention device contains a detecting unit and a control unit. The detecting unit includes a single crystal microprocessor connecting with a temperature detector, a gas detector, a smoke detector, a sound generator, an automatic dialing circuit, and a wireless transmitter circuit, such that when a gas stove is not turned off to cause a continuous gas burning, an abnormal temperature or smoke generates, and the wireless transmitter circuit transmits a wireless signal. The control unit includes a wireless receiver circuit, an electromagnetic valve connecting with the wireless receiver circuit, and the electromagnetic valve having an air inlet coupled with a gas hose and an air outlet connected with a gas inlet hose of the gas stove, such that after the wireless receiver circuit receives the wireless signal from the wireless transmitter circuit of the detecting unit, the electromagnetic valve is driven to turn off gas.
