 There are many kinds of alarm devices widely used, especially vehicle alarm devices. There is a short-range control method using a key-type remote control, that is, a car-host has a key-type remote control, which detects and alarms the vehicle within a short distance. deal with. When the parking position and the owner are beyond the perceptible range of the human body, the owner cannot know the alarm condition of the vehicle. There are audible alarms. When a theft occurs, the car will sound an alarm. However, with the increase of urban vehicles, the number of vehicles in the parking position will increase. Even if there is an alarm, it is difficult for the owner to confirm whether the alarm is caused by his own vehicle. Both the work and rest of the car owner will be disturbed, and false alarms will occur. All these alarm devices have the problem that they are not tamper-proof. When the alarm device is damaged or is powered off, the alarm device cannot work normally, and the alarm device has a single function, cannot control the car to do any action, and cannot use the existing huge Network resources.

There is a certain time interval between the two actions. After receiving the alarm signal, the car owner can call the car phone, and after receiving the car owner's call, the car phone can perform door lock control and on-site alarm actions, so that the attempt of the car thief cannot be succeeded.
