Embodiment 1

[0035] Embodiment 1. The NVR supports IPC access in a dual network port networking mode, and the first message includes a DHCP request message and a DHCP response message.

[0036] When the NVR supports dual network ports, one network port of the NVR is connected to the switch where the IPC is located, and the other network port is connected to the router where the DHCPServer is located. Such as figure 1 As shown, IPC1 and IPC2 are connected to the switch, the network port 1 of NVR1 is connected to the switch, the switch enables DHCP Relay, and the network port 2 of the NVR is connected to the router where the DHCP Server is located. The router can have a built-in or external DHCP Server.

[0037]When a new IPC is connected to the physical port of the switch, the IPC obtains an IP address uniformly through the DHCP Server; when the IPC sends a DHCP request (DHCP Request) broadcast message, the switch will contain the physical port information of the switch that the IPC accesse...

Embodiment 2

[0055] Embodiment 2: For IPC access in the NVR single network port networking mode, the first message is an ONVIF response message.

[0056] When the NVR has only one network port, the network port of the NVR is connected to the switch where the IPC is located, and the switch is connected to the router where the DHCP Server is located. Such as image 3 As shown, IPC3 and IPC4 are connected to the switch, the network port of NVR1 is connected to the switch, and the switch is also connected to the router where the DHCP Server is located, or the switch itself has a built-in or external DHCP Server.

[0057] In this embodiment, the switch can listen to the ONVIF protocol message between the IPC and the NVR, modify the IPC corresponding message of the ONVIF to obtain the device information message, and add the physical port information of the switch that the IPC accesses; the NVR receives the ONVIF After the message, obtain the physical port information of the switch, and the NVR ...

Abstract

The invention discloses an IPC access method based on a physical port of network access equipment, and an NVR. The method comprises the steps: adding physical port information of the PIC-access network access equipment in a DHCP message or an ONVIF response message, thereby analyzing the physical port information of IPC access after the above information is received by the NVR; searching an IPC channel record according to the analyzed physical port information; inheriting the IPC channel record and enabling the IPC channel record to serve as the IPC channel record of the IPC if there is the IPC channel record corresponding to the physical port information, or else, building a new IPC channel record corresponding to the physical port information, thereby managing accessed IPC according to the IPC channel record. The NVR comprises an analytical module and a channel record maintenance module. The method and NVR facilitate the implementation of the IPC management, and reduce the configuration workload of IPC installation and replacement.

Description

technical field [0001] The invention belongs to the technical field of video surveillance, and in particular relates to a method for accessing an IPC based on a physical port of a network access device and an NVR. 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 trend of popularization of video surveillance has become more and more obvious, and more and more tends to use IP video surveillance technology to replace traditional analog video surveillance technology. [0003] In the prior art, the application of accessing the IPC through the network video recorder NVR is becoming more and more common. The NVR can automatically obtain the IP address of the IPC and save it in the IPC channel info...
