Computers and hard disk video recorders need to be in the same local area network and the same network segment. The specific adjustment method is as follows:

1. Set the IP address of the computer so that the computer and the hard disk video recorder are in the same LAN and network segment.

2. Enter the address of the hard disk video recorder in the address bar of the computer IE browser (don't use other browsers), access the video recorder through the network, and enter the account number and password.

3. After entering the main interface of hard disk video recorder, find "Configuration" in the menu bar.

4. Enter "Configuration", configure corresponding parameter settings, find out "Video and Audio" and make relevant settings.

5. Select the channel number (corresponding camera) that needs to change the code stream, set the code stream type (the main code stream is in high pixel resolution mode, and the sub-code stream is in low pixel resolution mode), and set the parameters such as resolution, image quality and bit rate as needed. The larger the resolution value, the clearer the image (and the larger the network bandwidth).

6. After setting all the steps, click "Save" and the video recorder may restart automatically. After saving or restarting, log in to the address of the video recorder again to see if the modification has been completed.
