Create rules for appearance

Last modified: Tuesday March 17, 2026.

Create a rule to alert your operators when an object (person or vehicle) enters the field of view of one of your cameras.

Alta video will alert you when facial recognition is disabled on a camera that is configured with an appearance rule. An alert will also display when creating the rule for a camera that has facial recognition disabled.

Prerequisites

To use Camera templates or Date & Time Templates settings, make sure you have configured them before creating the rule.
