1. A visual domestic safeguard system comprising a host M and several slaves Z, slave Z is mainly used to obtain video signals while the principal function of host M is to transmit signals to a server through communication networks, wherein:

  • I) Slave Z includes video acquisition circuit (7), slave central processing circuit (8), slave wireless communication interface circuit (9), duplex speaker circuit (10) and control switches (11);

    the output of video acquisition circuit (7) is connected with the input of slave central processing circuit (8), which is also connected with the slave wireless communication interface circuit (9);

    the duplex speaker circuit (10) is also connected with slave central processing circuit (8), and control switches (11) are connected in slave central processing circuit (8). Mobile detecting algorithm may be implemented in the slave central processing circuit (8) with software;

    II) Host M consists of host wireless communication interface circuit (1), host central processing circuit (4), communication interface circuit (6), display output circuit (3), display device (12), memory circuit (2) and hard disk interface circuit (5);

    host wireless communication interface circuit (1) is connected with host central processing circuit (4) while the output of the latter is connected with the input of display output circuit (3), whose output again is connected with display device (12);

    host central processing circuit (4) can decode and decrypt the compressed video signals received by host wireless communication interface circuit (1) and then display them directly on the display device (12) through the display output circuit module (3). Host central processing circuit (4) has a communication interface through which it has a connection with communication interface circuit (6);

    there are also memory circuit (2) and hard disk interface circuit (5), both are connected with host central processing circuit (4);

    III) Slave Z and Host M may establish a wireless interconnection in two ways;

    one is analog mode and the other is digital mode.
