  • Method and device for passing through isolation device in surveillance network
    Patent number: 9215215
    Abstract: The present invention provides a method for a surveillance node to pass through a network isolation device in an IP surveillance system. The method comprises steps of using a first IP address of a surveillance node per se to initiate a tunnel connection request towards a tunnel server, so as to establish a tunnel connection with the tunnel server. After establishing the tunnel connection, the step is obtaining a second IP address distributed by the tunnel server from the tunnel server, and decapsulating a tunnel packet received from the tunnel server to obtain an inner-layer IP packet indicating the content is surveillance signaling. The method further comprises the step of processing the surveillance signaling, encapsulating the surveillance signaling generated by the surveillance node into the inner-layer IP packet, and then encapsulating the inner-layer IP packet into the tunnel packet and sending the same to the tunnel server.
