I have two spotlight cameras, each mounted on the soffet of a set of garages. One has yellowed (see attached). The other goes on during the day and stays on (on the right of the second picture). They were installed about 11 months ago.
They are linked to each other. All setting have been checked and they are on lower sensitivity, motion-only. They get about the same amount of sunlight and do not interfere with each other at night. Recording seems to work as it should.
I don’t think these should yellow. I also think the one that stays on is flawed.
