Area occupancy

Area occupancy is used to identify a crowd of configurable size in a designated area, being able to detect up to 50 people. This can be particularly useful for safety and security purposes, such as detecting overcrowding in public spaces or monitoring restricted areas.

  • Go to Video Search Advanced Search to set up a Search for area occupancy.

  • Go to Live Rules New Rule to set up a real-time detection of area occupancy with alarm integration.

Select Source

Select the video you want to run the Search on from the left sidebar. The thumbnail image of the chosen video is displayed here.

Time interval Advanced Search only

Time interval

Select a time frame for the analytics to run.

  • Entire video: Run the Search on the entire video duration, from the start timestamp to the end timestamp (set during video registration).
  • Custom range: You can select a custom start and end date and time to run the Search on. Type the desired date and time or select them by clicking the calendar icon.

Object Filter

  • Sensitivity (Medium by default): The sensitivity level of the Search. The higher the sensitivity, the more likely it is to detect a crowd, but it may also result in more false positives.

Crowd detection

  • Detection zone: Draw a polygon on the video frame to define the area where the objects will be detected. Left-click on the video frame to draw a polygon. Left-click again on the video frame to keep adding points to the polygon; double-click to finish drawing.

Drawing ROI is only supported on videos with a fixed camera angle (i.e. not on moving cameras). PTZ cameras are supported only in fixed position.

Note that currently only one ROI can be drawn.

  • Minimum people count (3 by default): The minimum number of people required for a crowd to be detected. Adjust this setting based on your specific use case and requirements.

  • Cooldown (in seconds, 5 by default): The minimum amount of time that must pass between two detections.

Alarm integration Live Rules only

You can choose to integrate the Search with an alarm system.; whenever a stopped object is detected, an alarm will be triggered in the integrated system.

Results

All done - Clicking Search will immediately start the analysis and opens the Search Results screen.

Live Rules will produce real-time detections , and the results will be displayed in the Alarms screen. If an alarm integration is set up, an alarm will also be triggered in the integrated system.
