The central display alarm system against theft for laptops consists of a central controller with 2, 4, 6, or 8 ports and specific cables with alarm function. There are several different types of cables that can be connected to a laptop computer and the central controller to protect them from theft. Usually cables with an adhesive sensor or cables with a USB connection are used. If a cable is disconnected or cut the alarm of the central controller will be triggered. The central controller is turned on by means of a remote control. Thus, the controller can be placed out of sight .
The central alarm controller can also charge so smartphones, tablets and smart watches are not only protected against theft but also charged.
