Cable anti-theft has the following three situations to realize the alarm
In the case of no power, the system completes the cable integrity test in the no-power state through the no-power communication technology. When the system cable is cut off,The alarm host can actively detect the state of the road and generate an alarm signal.
In the case of power, the system completes the cable integrity detection under the power state of the line through the power carrier sense technology.After cut off, the alarm host can actively detect the state of the line and generate an alarm signal.
In the case of power failure, the system completes the alarm function of the alarm host in the event of a power failure by connecting an external rechargeable power supply. When the device has no communication。When the power supply is input, the system can automatically switch to the external power supply, and realize the anti-theft of power failure by adopting the method of no power anti-theft.
