[0003] In the prior art, the optical access unit of these high-definition network cameras is a standard Ethernet transmission access and switching device. In theory, anyone can access the high-definition Network camera network, and then arbitrarily view the images of cameras at various points in the network, which seriously affects the security of the image monitoring network system

Embodiment Construction
[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0020] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0021] Such as Figure 4 , an embodiment of the present invention is applied in a high-definition network camera network connected by chained multi-nodes. The network includes several nodes, and each node is connected to the central terminal after being connected in series. For the convenience of a clear description, the nodes are divided into the node farthest from the central terminal and the intermediate node. The node farthest from the central end is only responsible for transmitting the image m...

The invention discloses a security and protection method for an open access network of a security and protection image monitoring device, and relates to the optical communication technology. The security and protection method solves the technical problem of preventing illegal access on network nodes. The security and protection method is technically characterized in that the node which is farthest away from the center end sends local image monitoring information to the next near-end node in the form of an Ethernet data packet, the middle node packages the local image monitoring information into the Ethernet data packet, data multiplexing is conducted on Ethernet data transmitted from the previous far-end node and the Ethernet data packet of the current node, the Ethernet data and the Ethernet data packet are sent to the next near-end node or the next center end, the center end receives Ethernet data transmitted from the node nearest to the center end, demultiplexing is conducted on the Ethernet data so that Ethernet data packets of image monitoring information of all the nodes can be obtained, and the Ethernet data packets of the image monitoring information are multiplexed into one route and input into the same port of an Ethernet exchange chip at the current center end in the form of the Ethernet data.
Description
technical field [0001] The present invention relates to optical communication technology. Background technique [0002] At present, with the trend of high-definition images, network high-definition cameras have become the mainstream image acquisition method. Accordingly, it is necessary to build an Ethernet optical fiber transmission network throughout every corner of the city to transmit these unattended outdoor camera images to the monitoring center. [0003] In the prior art, the optical access unit of these high-definition network cameras is a standard Ethernet transmission access and switching device. In theory, anyone can access the high-definition The network of network cameras, and then arbitrarily viewing the images of cameras at various points in the network, seriously affects the security of the image monitoring network system. [0004] especially if figure 1 In the above-mentioned ring or chain multi-access point optical fiber network, the network high-definiti...
