摘要： According to examples of the present disclosure, a method and apparatus for automatic white balance may be provided. A white region for performing automatic white balance may be obtained by a front end device of a video monitoring system. At least one cluster may be generated by clustering statistical points within the white region of a to-be-detected image by the front end device. The cluster may be determined as a target cluster and statistical points within the target cluster may be determined as white points by the front end device when the number of statistical points within the cluster is greater than a preset threshold. And a white balance gain of the to-be-detected image may be determined by the front end device based on the target cluster.

摘要： 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. The tunnel server forwards the inner-layer IP packet to a surveillance node of an outside network of a network isolation device. The present invention can effectively assist a surveillance node in a surveillance system to pass through a network isolation device, and solve various service problems caused by the isolation device.
