The EOC terminal module is used for coaxial power taking, and its power supply is converted to the direct current 12V of web camera needs or exchanges the needed power supply of EOC terminal module self in 24V power supply and web camera.

The EOC terminal module has the POE function of supplying power, and the EOC terminal module, as power supply unit, is given and supported the PD of IEEE802.3af or IEEE802.3at that power supply is provided.

EOC terminal module in web camera is based on IEEE1901 and HomePlug AV standard and EOC local side module and carries out the mutual of data.

Embodiment 1:

As shown in Figure 1, the up going port of EOC local side module connects switch, ONU or OLT, for video surveillance network provides up path, the descending coaxial mouth of EOC local side module is divided into two parts, the one, Cable mouth, this mouth connects descending coaxial cable, by connecting the EOC terminal module after distribution/prop; The 2nd, Power mouth, this mouth connects interchange 60V power module, by this mouth, is EOC local side module for power supply, and EOC local side module is down transmitted the 60V alternating current simultaneously, is transferred in coaxial cable, gives EOC terminal module and the web camera power supply of back.

Distribution/prop, as the main devices of coaxial cable, plays the distribution of network and the effect of network signal isolation, and the signal that EOC local side module is transmitted is distributed into multiple signals, connects a plurality of EOC terminal modules, realizes the management of a plurality of EOC terminals.

The effect of EOC terminal module is coordinate EOC local side module settling signal mutually mutual, and coaxial mouthful connects up link, network interface interconnection network video camera, and this mouthful of one side provides data link for web camera, provides power supply for web camera on the other hand.

The data port of web camera connects the network interface of EOC terminal module, realizes the two-way interactive of IP data.

The supply power mode of the current main flow of web camera has three kinds: 1, POE power supply 2, AC24V power supply 3, DC12V power supply; Three kinds of supply power modes are according to circumstances optional.The POE power supply distance is far away, can reach hundred meters distances, be applicable at a distance can't power taking application scenarios.Power interface connects the power interface of EOC terminal according to the power supply type, or directly from network interface, passes through the power taking of POE mode.

The EOC terminal can be converted to the AC60V power supply on coaxial network above three kinds of forms, for the POE supply power mode, be equivalent on the basis of the coaxial network of growing Distance Transmission, increase again the transmission range of nearly hundred meters netting twines, made the topology distance of web camera obtain larger extension.

Because the EOC network maximum transmission distance based on HomePlug AV standard can reach 1km, other traditional approach transmission ranges of comparing increase greatly; Although Optical Fiber Transmission also can solve the problem of long Distance Transmission, but the power supply of Optical Fiber Transmission is a problem, must be in the power taking of web camera near-end, this just needs to dispose in addition power line to the web camera near-end, needs extra quantities and the Material Cost of increasing.
