Configure Camera image health monitoring

Last modified: Wednesday July 30, 2025.

You can configure AI-powered video analytics to monitor significant changes to a camera view over time, for example, if a camera moves, the lighting or focus changes or if the image becomes blurry.

Using two reference images from footage recorded by a camera, Alta Video checks twice per day for major changes between the current camera view and the reference images. You can create camera rules to notify you of any detected changes. See Create rules for camera issues.

You can create an image health report from Alta Video. This report will provide the current image as well as the two reference images.
