Logical Rule
The MEGApix® IVA/IVA+™ camera’s Logical rule can be configured to combine various rules and inputs using logical expressions, to reduce false events. A Logical Rule can combine multiple rules into a single condition. Objects are checked against all combined rules before they become an event and trigger an action, also known as a ‘double-knock’ rule.
This article will outline how to create a Logical rule using the camera’s IVA analytic options.
Supported/Affected Devices:
- MEGApix® IVA/IVA+™ Camera Series
