How does the recorder add two cameras on different network segments?

How can the video host add cameras with different network segments? This may be encountered in actual projects, and many friends are asking. We have a general introduction in the previously published content. In this issue, we will summarize in detail how to implement the camera to add cameras with different network segments. There are two methods commonly used.

Use dual network port recorder to add cameras on different network segments

We can use a dual-network-port recording host to add cameras on different network segments. Generally, dual-network-port video recorders have two working modes, network fault tolerance and multi-address setting.

When adding cameras of different network segments, the multi-address setting mode is generally used. It is assumed that the recording host is a 192.168.1.x network segment and the camera is a 192.168.0.x network segment. In this way, add a camera.

Step 1. In the main menu of the recorder-system configuration-network configuration-basic configuration, change the working mode to multi-address setting, select LAN1 for the network card, and set the recording host IP to 192.168.1.100. Therefore, LAN1 is selected by default.

Step 2: Connect the camera

The switch on the camera is connected to the LAN2 port of the recording host, the network card selects LAN2, and the IP address of the recording host LAN2 is set to 192.168.0.100.

The recording host has two IPs. LAN1 is used to connect to the external network for remote access. LAN2 is used to add cameras on the same network segment, and then add cameras in channel management-IP channel management, so that different network segments can be added. camera.

Modify the subnet mask

You may ask if there is a simpler way for the weak current industry network. Actually there are. For two different IP addresses in general, a simpler method can be done by modifying the subnet mask, and then add it directly. Too many settings.

Example: For example, the IP addresses of two network segments: IP address one is 192.168.1.x and IP address two is 192.168.0.x

If you don't want to set it, generally we can change the subnet mask from 255.255.255.0 to 255.255.252.0. Of course, some friends will directly change to 255.255.0.0, but it is recommended that the subnet mask be as accurate as possible.

The principle is actually to change different network segments into the same network segment. Here is also explained that the role of the subnet mask is to obtain the network IP address and divide the network.
