Configure Exposure areas

Last modified: Tuesday February 25, 2025.

You can add Exposure areas to Avigilon Alta cameras to improve the quality of the video.

In large areas, such as near windows or by a light source can cause under-exposure. Similarly, in large areas which may be dark could cause over-exposure. By creating exposure masks over the under or over exposed areas will improve the video quality.

Exposure areas are not a supported feature for PTZ cameras.

If HDR is enabled then exposure areas are disabled.
