In our project, NVR is installed in an outside cabinet, with other switches, and controllers. The cabinet is not commissioned yet/ the devices are not running. Our outside temp is -20C. The heater in the cabinet is OFF. The contractor mentioned that the heater will be ON, only when the devices will be working. Can we leave the installed NVR and electronic devices, not powered, in freezing condition?
 
+1^^, especially electrolytics.
I sure wouldn't leave it at -20C with no ambient temp control within the storage AND operating range of all the components.
 
Thats how cold the electronics are when Amazon puts them on any Minnesota porch. My iphone 14 was stuffed in a mailbox for 24 hours with temps around +5 to -7F.
My Amcrest NVR's are on thier 3 rd year out in a garage. right now it's 7F in the Garage. :idk:
but thats not quite your scenario.
Cars sit outside all year here, don't they have Lectronics in em?

I wonder how cold it is for the Starlink Internet satellites.
 
This is the environmental specs for a typical Netgear POE switch.
Gigabit Plus Switch Series (JGS524PE)
24-Port Gigabit Plus Switch With 12-Port PoE

I would imagine that most other IP electronics are similar.

FWIW, that's a "storage" spec, the "operating" is 0 to 40C; granted that the ambient will be warmer when operating, can't say if it would raise the ambient by 20C and don't know about the OP's NVR operating temp specs either. Heck, I'd give it a shot. :cool:

Yes, it is. That is what the OP is asking about, right? The equipment is not yet turned on, so no heat in the cabinet. Basically it is in storage mode.

Yes, right you are. As the late Gilda Radner would say......

While I can't advise you what to do, I would think that being in a cardboard box or in your metal (I imagine) cabinet would not be any different. They both would ultimately reach the temperature of the surrounding environment.
