In security video analytics scenarios, alerts are triggered when a change is detected in a defined area. For example, when a person enters the area, or when an object is left in the area. Alerts indicate that a Security Center event is generated.
Alert bar in Config Tool
When configuring a security video analytics scenario, you can use the alert bar to see whether an alert is properly triggered from your configuration. The alert bar is displayed in the top left corner of the video on the Areas and General pages.
If you do not click Apply to save your configuration, you can still see alerts being triggered from your configuration, but no corresponding events are generated.
- The bar is blue when no alert is triggered.
- The bar is red, when an alert is triggered, and then turns back to blue after the
Alert cooldown period has elapsed. When the bar is back to blue,
new alerts can be triggered.
Alert overlays in Security Desk
Alerts can be visualized when monitoring video analytics cameras if you enable the Alerts overlay in the scenario configuration.
In the Security Desk Monitoring task, the camera associated with the Area protection scenario is monitored. The Alert overlay is enabled in the scenario configuration, so when the alert is triggered, the outline of Area 0 is displayed in orange, and the associated event is listed in the event list.
