Problems solved by technology

[0006] The above-mentioned technical solution of manually deleting the IPC and then adding it, the configuration process is redundant and complicated, and if the IPC is a third-party IPC, it will be even more troublesome. All work needs to be manually configured, which requires high technical knowledge and is difficult for ordinary users to complete.

Embodiment Construction

[0044] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0045] The technical solution of the present invention is mainly applicable to the following scenarios: when the access management device adds the access device and then changes the access device to a static address and then accesses the external network router, the access management device dynamically obtains the IP address and causes the IP address to change. The IP address is not in the same network segment as the access device.

[0046] It is easy to understand that in a video surveillance system, NVR is an access management device, and IPC is an access device. The following embodiments take NVRs and IPCs in a video surveillance system as examples for description, and the same applies to access management devices and access devic...

Abstract

The invention discloses a method and a device for keeping an access device online. An access management device obtains an IP address through a dynamic address allocation protocol DHCP, and when an IP address change occurs, it obtains the DHCP address when judging that the added access device is not online. After the address pool is allocated by DHCP, modify the original address to communicate with the network of the original access device, and modify the access device to the address of the DHCP network segment. After the modification is successful, modify the access management device back to the DHCP address. To ensure that the access device is always online on the access management device. The invention not only reduces the operation of the access equipment, but also reduces the manual configuration on the access management equipment, and significantly improves the user experience and reduces the configuration cost.

Description

technical field [0001] The invention belongs to the technical field of equipment installation and maintenance, and in particular relates to a method and device for keeping an access equipment online. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuitive, accurate, timely and rich information content. In recent years, with the rapid development of computer, network and image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. [0003] In a small video surveillance system, the simple network hard disk video recorder NVR plus network camera IPC networking form is the most commonly used, among which, the NVR is responsible for managing and accessing the IPC. [0004] In many cases, the networking structure is as follows figure 1 As shown, first connect the NVR and IPC to a switch (Switch), the ...
