"I have spoken to tech support but didn't get a fix for it."
Tech support for Axis or tech support for your switch provider? Either way, what did they suggest?
This would help us provide better feedback / not duplicate what they have already said.
I had issues in the Q6032-E days (~4years ago) with condensation, not shutdown.
Sweden provided a custom firmware at the time.
Further along, the Q6034-E and Q6035-E seemed to work better for us, out-of-the-box.
We do get -40 in our area.
Sorry, but I have no experience with the newer 45's. I would have expected the cold weather issues would be a thing of the past.
I always bemoaned that the Q60xx-E's never had a 24VAC option. Would make migration from 24VAC analog PTZ poles easier.
I realize I'm not of much help ...
Are you using the Axis 60W midspan that ships with the camera or just a POE switch?
I am using the 60 w midspan included which according to tech support is really 75 watts ,60 usable.I am using it with a american fiberteck poe unit which is 50 watts and around -25 it stops producing enough power and i have to put midspan to boost and then not all cams but some quit around -35 or so.I am using it with exacqvision server and every now and then it drops a camera.I updated cams and server which improved situation 10 fold.
