The Cam Pan V3 has a critical flaw in the mechanical tolerances for the gears responsible for pan & tilt. Firmware fixes attempting to mitigate the affects of this flaw have been largely unsuccessful.
The original reporting and discussion of this issue is in the thread: Wyze Cam Pan v3 - Does not return back to home position
The status of this flaw is being updated in the thread: Wyze Cam Pan v3 Drift Update
Even with the Track Motion or Scan Features off, if the cam turns off (privacy mode), gets manually adjusted, updates firmware, or experiences a power cycle or power loss, the cam will recalibrate and return to a home position that could be slightly off from the original position.
