The photographing device includes a power line network bridge and a first router, and can be connected to Internet through the first router, the power line network bridge and a first power line. The surveillance device includes a second router and is connected to Internet through the second router. The peer-to-peer server connects the first router and the second router through Internet.
In general, the user must accomplish the time and labor works consuming network wiring and complicated IP setup that images of the IP camera can be seen or electric equipment can be controlled, through Internet. As the photographing device of the present invention includes the power line network bridge, the user can use a PLC (Power Line Communication) technology to save a trouble of network wiring. In addition, as the present invention includes the peer-to-peer server, a P2P (Peer to Peer) technology can be used to avoid setting up an IP.
As a result, an ordinary person does not need to do the network wiring, or to know how to set up an IP. On the other hand, the surveillance device of the present invention can be a mobile phone or a computer and the user just only uses the computer or the mobile phone that he or she can easily monitor images at home or control the electric equipment, and at a same time, receive the alarm signal detected by the alarm equipment, through Internet.
