Introduction
If your camera is installed outdoors, it will likely experience varying lighting conditions throughout the day. In addition to the standard default optical settings (All Day mode), the camera also provides recommended optical parameters for four specific time periods: Dawn/Sunrise, Day, Dusk/Sunset, and Night.

Follow the steps outlined in the the document to enable these four specific parameters and configure a schedule to apply them at the appropriate times, ensuring the best image quality for your outdoor environment.

This document also includes two Case Studies addressing overexposed license plates at nighttime, providing a step-by-step walkthrough of the required optical adjustments.
