1. An antitheft system with signals transmitted by mobile phone network comprising:
- a CPU controlling the internal circuit;
a video signal converter being connected to said CPU, used to convert analog video signals into digital video signals and send those to said CPU;
a plural numbers of video camera each being linked to a said video signal converter, used to capture video signals and send the video signals to said video signal converter;
an audio signal converter being connected to said CPU and serial with an amplifier, a speaker and a microphone, said microphone receives the analog audio signals, said audio signal converter converts the analog audio signals into digital audio signals and sends them to said CPU, or said CPU sends the digital audio signals into said audio signal converter that converts the digital audio signals into analog audio signals, being amplified by said amplifier, finally output through said speaker;
an audio/video compression/decompression circuitry being connected to said CPU, used to compress or decompress the audio and video signals received;
a hard disk drive being connects to said CPU, used to store above audio and video signals;
a mobile phone interface being connected to said CPU and a mobile phone for transmitting and receiving audio and video signals to and from the mobile phone network;
an I/O interface being connected to said CPU, a push button on the I/O interface to trigger the starting signal.
