Hi, dear!
At first you have to know that you can adjust camera types and images to meet different surveillance scenario requirements.
ISP parameters are associated with each other.
You must set the ISP parameters based on the site requirements to prevent poor image quality or overexposure.
Log in to the IPC web page as the admin user.
Choose Settings > Channel Configuration > ISP Parameters. The page for setting cameras and Image Signal Processing (ISP) parameters is displayed as shown below.

Set ISP parameters.
Thanks!
