Counting in Crowded Situations
Depending on your situation, you can set a VT module to count more or less conservatively when it comes to one person following another. In a very crowded situation, where people are packed closely together, you can set the VT to allow only a little time between people. In a less crowded situation a more conservative option is better since it prevents false detections of shopping trolleys and the like. The system defaults to the conservative option, to change this to crowd counting follow these steps.
- Select the VT module which is monitoring your entrance.
- In the Settings list, set the TimeoutRestore value to 1. This enables close following. (If you expect shopping trolleys or lots of children's buggies, leave the TimeoutRestore value at 0.)
- Click the Apply to VT button.
- If you wish to set other VT units to count crowds then go to the Settings tab and click button 5, Copy settings to higher address numbers.
