If a Dwell zone is created that is smaller than the size of the dwelling object, the Dwell plug-in will consider any object that envelops the zone as dwelling in the zone. This allows for the creation of Dwell “hot spots”, specific points of interest where you wish to capture Dwell events.
Setting Minimum Size
A Minimum Size must be established for each camera bound to the Dwell plug-in. Once set, the plug-in will only analyze the video feed for dwelling objects larger than the specified size. Smaller objects will be ignored. The minimum object size should be configured with the size range of targeted objects in mind.
To set the minimum object size:
In the Edit Settings window, click the Minimum Size tab.
Click and drag the orange box until it is the desired minimum size. The positioning of the box in the video player is irrelevant.
Saving Settings
When you are finished editing the Dwell settings for the current camera, click the OK button at the bottom of the Edit Settings dialog. Repeat the steps in this section for any remaining cameras bound to the Dwell plug-in.
Finalize Configuration
Restarting System Software
In the Configure panel, right-click the appliance name and select Restart 3VR Software.
In the pop-up box that appears, click Restart to proceed. Wait 1-2 minutes for the software to restart.
Verifying Successful Configuration
To verify that the Dwell plug-in has been correctly configured, check for recent Dwell events in 3VR OpCenter:
In 3VR OpCenter, click the Monitor tab to go to the Monitor panel.
Click camera numbers to select the cameras bound to the Dwell plug-in.
Click the arrow below the camera selector to open the event type drop-down menu.
Select [ ]Dwell and click OK.
If the plug-in has been correctly configured, Dwell events will appear in the Monitor panel in real-time.
Verify that Dwell events are being generated correctly on all cameras bound to the plug-in during configuration.
Fine Tuning Plug-in Performance with Optional Settings
The settings in the Parameters tab of the Edit Settings dialog should only be modified from their defaults if Dwell results are unsatisfactory.
Minimum Dwell Time (seconds) The minimum amount of time an object must dwell before a Dwell event will be generated. | Default: 10 |
Down sample Factor Controls how the video resolution is down sampled before analyzing for Dwell events. When left at 0 (default), the plug-in will use the full resolution of the camera, which is highly CPU intensive. Installations running many Dwell cameras (or other analytics) at the same time may see improved performance by increasing the Down sample Factor of each Dwell camera. | Default: 0  |
