Motion detection too insensitive?

[Ruugy]

Hello,

is the motion detection from the YI Pro 2K(3MP) Model y623 (with YI Hack Allwinner v2) too insensitive or or does it not work reliably?
How big or how small can the object be for movement to be detected (human, cat, mouse; at 1-3 meters)?

I have set the motion detection on (so the AI Detection - off)
AI Detection requires plan.
Sensitive is high

The IR is on, because it is relatively dark at the mounting place.
Thank you very much

Change it to medium or low.
I have a y623, too. Insects are detectable.

I have set it to medium now.

Before i set it to high. Is medium better than high?
