Camera properties -> Motion/Trigger -> Object detection - Edit: Reset detector when: Object size exceeds
Maybe I'm a bit slow on the uptake, but I have only just noticed this setting. I have however noticed that when the cams switch from day to night mode they no longer set of a motion alert, with the exception of the one cam which isn't using object detection.
It looks like 67% is set as the default for any cam with object detection enabled. I'm assuming that the % relates to the entire image, rather than the active mask/s area. If anyone knows for sure please say.
This could be a great feature for eliminating false alarms due to lighting changes etc, but I'll be watching it closely to see how it affects alerts in general. I suspect some cams it will be ideal for, but others, where you want to catch someone walking past very close to the camera for instance, it might cancel wanted alerts.
Of course it won't be of any use to those who choose not to use object detection in order to have maximum motion sensing sensitivity.
Use the Object size exceeds setting to reset the motion detector when very large objects are detected. This will help to prevent false positive triggering in the event of scene or major lighting changes.
