I don’t know about the heat, but people have been reporting running them in very cold temps this winter. So you should be fine to put it up there now at least long enough to identify the critter. Post a video of your friend when you catch him!
Hello, I posted a similar question for my solar attic exhaust fan. I live in Florida and it is very hot now.
I wanted to be able to see if the fan was working. The Wyze cam has been up in the attic
over two weeks now!
I have had a camera in the attic for the past year and also under an eve in Chicago’s weather without any issues. We had 40 below this year and the cameras worked perfect even the one outside. For $20 they are the bargain of the year ! Attic temp lately 110
