Disappear Rule

The MEGApix® IVA/IVA+™ camera’s Disappear rule can be configured to trigger an alarm when the camera loses track of an object within the detection zone, without crossing out of the zone’s border.

This article will outline how to create a Disappear rule using the camera’s IVA analytic options.

Supported/Affected Devices:

  • MEGApix® IVA/IVA+™ Camera Series

Creating a Disappear Rule

MEGApix IVA Training Video - Creating Disappear Rule from Digital Watchdog on Vimeo.

To create a Disappear rule:

  1. From the camera’s Web Client, click the Setup button to enter the Configuration menu.

  1. Click on IVA from the Configuration menu, then select Rules.

From the Rules menu, click the Add button and select Enter.

  1. A detection zone will overlay the camera’s video in the preview window.

Position the zone so that it masks the area of interest.  Click-and-drag the colored nodes (corners) to adjust the zone’s size and shape.

To create a more complex shape, click one of the gray nodes to add a new segment to the detection zone.

To delete a segment, click the minus sign next to any of the nodes.

  1. You may configure the following options:
    • Name – enter a label for the rule
    • Object Filter – set this option to ON to allow the rule to only trigger based on the classification of an object (e.g. person, vehicle, etc.)
    • Classes – to use this option, the Object Filter option must be set to ON.  Select which object classification types will trigger the event alarm upon crossing into the detection zone.  The selection options can be changed in the IVA > Classification menu.
    • Event Notification (TCP Event) – enable for TCP notifications when event is triggered
    • Event Notification (HTTP Event) – enable for HTTP notifications when event is triggered
    • Triggered By – select to have the event action be triggered by an object or by an Action Rule (set up in camera’s Action Rules menu)
    • Triggered At – select to have the event action trigger at the beginning or at the end of the event
    • Action Rule – you may select an Action Rule to activate when the event is triggered
    • Convert IVA to MD – enable to allow camera to pass IVA event through the camera’s event engine using the camera’s ONVIF stream

  1. After configuration the detection zone, Rule Properties, and Event Actions, click the Save button to apply the settings and create the Disappear rule.
