Problems solved by technology

[0004] The purpose of the present invention is to provide a network video recorder and its method for automatically connecting to the IPC, so as to avoid the problem that the IP address of the IPC in the network cannot be modified and it is difficult to add it to the NVR, and it is convenient for users to deploy a video surveillance network

Embodiment 1

[0046] Embodiment 1, the case of a single network card, that is, the NVR has only one network card. After receiving the response message from IPC3, NVR judges that the IP address of IPC3 is not in the same network segment as its own IP address, and selects an IP address in the same network segment of IPC3 (172.168.1.2~171.168.1.254) , such as 172.168.1.30, the NVR continuously pings the IP address, if the pings are different (no response reaches the preset number of times), the IP address is considered available, and this IP address is added to the NVR network card as a virtual IP, and the follow-up The communication with IPC3 is carried out through this virtual IP address. If the ping is successful, change another IP and continue pinging until a suitable virtual IP is found, or establish an assigned IP management information table, perform idle IP query, and find an unused IP address as a virtual IP, which will not be repeated here.

Embodiment 2

[0047] Embodiment 2, the situation of multiple network cards, that is, the NVR has multiple network cards. The difference from Embodiment 1 is that for the case of multiple network cards, since there are multiple network cards such as network card 1 and network card 2 in the NVR, the IP address of network card 1 is 192.168.1.10, but the IP address of network card 2 is 172.168.1.10. In this case, for the received response message, first compare the IP address of the IPC that sent the response message with the IP addresses of each network card to check whether there is a network card in the same network segment as the IPC, if there is only one network card If the IP address of the network card and the IP address of the IPC are in the same network segment, then bind the IPC and the network card; if there are multiple network card IP addresses and the IP address of the IPC in the same network segment, the How many IPCs are specified, load balancing is performed, and the network ca...

Abstract

The invention discloses a network video recorder (NVR) and an automatic IPC (Internet Protocol Camera) access method thereof. The NVR comprises a device discovery module, a network configuration module and a configuration management module. The method comprises the steps: sending an ARP (Address Resolution Protocol) broadcast message, and receiving response messages fed back from all IPCs, wherein the response messages carry own IP (Internet Protocol) addresses of the IPCs, subnet masks and port numbers; judging whether the IP address of each IPC sending the corresponding response message and the IP address of an own network card of the corresponding IPC are located in the same network segment or not according to the received IPC response messages, and going to next step if the IP address of each IPC sending the corresponding response message and the IP address of the own network card of the corresponding IPC are located in the same network segment; adding a virtual IP address, which is located in the same network segment of the IP address of each IPC sending the corresponding response message, to the own network card of the corresponding IPC if the IP address of each IPC sending the corresponding response message and the IP address of the own network card of the corresponding IPC are not located in the same network segment, binding the corresponding IPC and the added virtual IP address to the corresponding own network card, and going to the next step; adding corresponding IPCs in a unicast mode. According to the NVR and the automatic IPC access method thereof, the access of the IPCs which do not support IP modification is subjected to IP removal, and the IPCs and the NVR can be in interconnected use in a zero configuration manner.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, in particular to a network video recorder and a method for automatically connecting to an IPC. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. Deploying a video surveillance system based on an IP network has become the most commonly used networking method, such as figure 1 In the video surveillance system shown, both the network video recorder NVR and the network camera IPC are connected to the same egress router, and users can access the client terminal under the egress router to view the video images of each IPC, or they ca...
