Method for processing monitor service and network video recorder (NVR)

Abstract

The invention provides a method for processing a monitor service, wherein the method comprises the steps of receiving a monitor service request which is transmitted by a virtual memory (VM) in a central domain by a network video recorder (NVR), and informing a monitor service request terminal to establish a channel with the NVR; allocating an address to the terminal from a private network address pool, and establishing route information which points to the terminal; sending a signaling of processing the monitor service to the terminal by the NVR through the channel, and sending the signaling of processing the monitor service to a coding terminal under the management of the NVR; receiving a monitor service data packet which is sent by the coding terminal by the NVR, transferring the monitor service data packet to a channel interface which is connected with the monitor service request terminal depending on a route which points to the monitor service request terminal to send the data packet to the terminal through the channel. Owing to the establishment of the channel, the treatment for sending the private network data packet to the outer network by the NVRis just transferred depending on a channel route which is established in the local part, thereby reducing the performance consumption, and simplifying the maintenance and management of the outer network central domain equipment on the private network equipment under the NVR.

Description

technical field [0001] The invention relates to video monitoring, in particular to a monitoring service processing method and an NVR. Background technique [0002] IP is the abbreviation of Internet Protocol (Internet Protocol), which is the most commonly used protocol for communicating through computer networks and the Internet. IP video surveillance system (also known as network video surveillance system) can digitize video information and transmit it through wired or wireless IP network. This enables functions such as real-time monitoring and video recording to be extended to all places with network connections, and also enables such systems to be easily and seamlessly integrated with other security systems (such as access control systems, etc.). Formally based on the above characteristics, at present, the IP video surveillance system is developing towards the direction of "unified deployment + data sharing" IP surveillance network.

Problems solved by technology

[0004] When the devices in the above-mentioned central domain order the video streams of the encoding terminals in the NVR private network, the VMs in the central domain participate in the signaling control of the service, but in fact these encoding terminals are devices managed by the NVR, and VMs need to participate in each It is not very suitable to control the encoding terminal business under NVR

And when NVR is processing business data, each video data packet needs to be sent out after unpacking and packet processing, which will consume CPU resources of NVR

In addition, if the equipment in the central domain wants to directly maintain and manage the encoding terminal, such as upgrading the encoding terminal and modifying relevant configuration information, it will be very difficult
