Possible causes and solution(s)
Solution
Note: This experienced behavior is not caused by a wrong usage or defect, but result of a not optimal factory calibration. Note: Before start, it might be handy to activate "crosshairs", not all camera models have this. For example you can activate this on a MIC9000i (see below), but not on a AUTODOME IP starlight 5000i IR
In the attached example video we used: AUTODOME IP starlight 5000i IR FW 7.81.0060
First step is to calibrate the camera:
Reboot the camera first
Zoom in to a good recognizable place
Issue AUX ON 804 > move gray dot to a calibration target (at least 3m from cam)
Issue AUX ON 804 again > cam zooms out to 1x, if dot has moved use PTZ to move it back to the calibration target (you may want to use full and big screen)
Issue AUX OFF 804 > calibration finished
In the "Camera Calibration" video attached you can see an example of camera’s calibration.
Next step is to properly draw the mask(s):
First zoom in as close as possible on the target that you intend to cover
Now enable the mask of choose, a rectangle box appears, shape this according the target
Always draw the mask bit larger than the object you like to mask
Choose 1 larger mask, above multiple tiny ones, in case this is possible
Enable "mask enlargement"
In the "Draw the mask" video attached you can see how to draw the mask.
