Best would be with Video. Has someone experience with it and can suggest me a product? Note 1: We have currently -10°C on the Farm and it can go down until -30°C (some years ago it was for one day -39°C), which increase the requirements on the Interphone. Note 2: In 2017/2018 i used a Banana PI at a Sidele Interphone, but the BPI gaved up at -5°C and the Siedele at -20°C.By "Interphone", do you mean a local voice and/or video system that doesn't connect to the general Internet?
Based on another reply, I think they meant an intercom/doorbell system. The sort of thing that sits on an outdoor wall.
If it's SIP based then I presumed a local PBX, but I might be wrong.
I would suggest building a small insulated box to hold your electronics, along with an incandescent lightbulb to provide both light and heat.
If I guessed right, I agree with you! There's not much out there that will go down to -30C without some sort of heating element.
