Floodlight cam pro 2 360

Floodlight cam Pro 2 360 does not go back to it’s exact #1 pre set position, and at night it does not detect person very well at all

I have issues with motion detection as well it seems that sometimes it will detect and sometimes it won’t and I have it on maximum sensitivity as well. Tried all motion and human only

Same problem with motion detection, night vision is not detecting humans. Previously was working well then just stopped.
