Advanced Configuration
Step 3 Click Relearn. The camera automatically calibrates the depth of the FoV based on people
walking in the scene. Be sure that people are walking along the entire vertical axis of the
FoV until calibration is finished. The On-Screen Display shows the progress as a
percentage in the upper left corner of the video (see Figure 3-1).
If the calibration takes too long, the scene may require manual calibration.
Step 4 After calibration is complete set up detection areas and check calibration. Refer to Global
Settings, pg. 53, Creating Analytics Regions, pg. 53, and Check Calibration, pg. 55.
Manual Calibration
Step 1 On the camera’s Analytics web page, click the
Calibrate icon.
Step 2 Select Manual for the Calibration mode.
Step 3 Set the near size aspect ratio for a person. Have
a person walk around at the bottom of the area.
Select the blue box at the bottom of the screen
and drag to fit the subject. Click Save.
Step 4 Set the far size aspect ratio for a person.
Have a person walk around at the top of the area. Select the blue box at the top of the
screen and drag to fit the subject. Click Save.
Step 5 After calibration is complete set up detection areas and check calibration. Refer to Global
Settings, pg. 53, Creating Analytics Regions, pg. 53, and Check Calibration, pg. 55.
Based on these settings, the analytics calculate a human size that is proportional to the near and far
size calibration over the detection area. The vehicle size is extrapolated from the human size. If a
detected object matches these parameters, a box will be labeled either H for human, V for vehicle, or
O for object of interest.
