Purpose of AI Scan
what exactly is the purpose of the "periodic AI scan" setting?

The "periodic AI scan" setting in Blue Iris serves several purposes, primarily aimed at making the motion sensor "smarter" and reducing false alerts by leveraging Artificial Intelligence.
Here are the key aspects of its purpose:
- Finding Static (Non-Moving) Objects: Originally, this scan was designed to identify static objects in a scene so that they could be ignored by alert confirmation. This helps prevent static elements from continuously triggering motion detection.
- Becoming a Trigger Source: The periodic AI scan has evolved to the point where it can independently act as a source of triggers and alerts.
- Timed Schedule and Dynamic Scanning:
- By default, the scene is analyzed every 120 seconds.
- However, if the scene changes (objects appear, move, or disappear), the scan frequency increases to every 5 seconds.
- An object must be present or missing for a specified "make/break time" (a number of seconds) before it is considered static or removed from the static object watchlist.
- Defining Rules: You can define rules to be applied to the static object array as a result of these scans, which can then trigger or alert the camera.
- The trigger source for these events will be shown as "AI" in the database.
- You can specify object labels (with wildcards allowed) and a minimum confidence for these rules.
- The "Regard as NOT static" action can prevent specified objects from ever being considered static, overriding the normal static object functionality.
- Rules can trigger the camera or immediately alert in various ways. Options like "trigger set" and "trigger reset" should be used carefully as they override the normal trigger break time and must be matched.
- You can set a minimum time for an object to exist (abandoned) or not exist (missing) before an action is fired.
- "Bidirectional" rules can detect objects as they both appear and disappear, firing once. For "exist/not exist" senses, repetitive firing of the trigger or alert can be chosen.
- Optional Memo: An optional memo can be specified for the trigger or alert generated by a periodic AI scan.
In summary, the periodic AI scan provides a layer of intelligent analysis to constantly monitor the camera's view for object presence or absence, allowing for more sophisticated and precise triggering and alerting behaviors beyond traditional motion detection.
