#202887 — Interphone with SIP-Protocol

Hello Guys,

OK, I live now since last year permanently in Estonia and have now a 4ha
(13ha max) Organic Farm with 5,6ha forest.  Because I live in a loghouse
I have build a fire and storm proof "Serverbunker" where my Intranet
Server with its own power supply reside (the Mainpower supply will be
cut at stomy weather).

>From theis Serverbunker I go (Lighting protection) with Multimode Fiber
Cabesl (100Base-FX) to the House, Powerstation, Greenhouse, Earth-
storrage and of course to the Portal.

Because my Portal is in a distance of 60m from the Serverbunker and I do
not like to install a seperated earth cable, I am now searching for an
IP/SIP based Interphone.  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.

Thanks in advance

Quite an interesting issue. I would probably go down the route of a 
'tough' Android phone with a SIP app like linphone.

I have used 'runbo' phones before and they were good. Not sure about the 
temperature specs though.

Just an alternative idea for you to think about.

I do not think, it is a good idea to have such tough outdoor phone
for several 100€ outside alone only 2 car hours away from the
russian border...

Just speak Russian on the phone and be happy :)

Or better yet, Navajo or Cherokee. Neither language has even a tendril of 
a root in any other language on this ball of rock.

By "Interphone", do you mean a local voice and/or video system 
that doesn't connect to the general Internet?

As for your environmental requirements: does it have to operate
at -40, or just survive it for a few hours before warming back
up? Very few electronic devices are guaranteed to work below 0C.

I would suggest building a small insulated box to hold your
electronics, along with an incandescent lightbulb to provide
both light and heat. 

For general voice use, I like the Polycom IP3xx series. Their
video phones, however, are either very expensive or else consist
of a voice phone with a USB camera glued to the top.

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.

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.

Polystyrene boxes are cheap and widely available. You could even
afford to nest them.

I'd grossly underrun any light bulbs so you don't have failures, and
I'd be tempted to use bulbs with blade-type connectors, perhaps
smeared with silicone grease so they don't corrode.

Cheers,
David.

By Interphone I mean the door phone.

I think, "Interphone" is used in french
and in german it is called "Türsprechanlage".

But I like the idea of using the SIP Protocol, because I can redirect
the doorphone to any places of this planet.  Even if I am not at home,
I can see people ringing ar the door

-40°C is very rare but it has to survive.

Normal estonian winter temperatures are between -15°C and -25°C.
So, the doorphone/interphone should work in this range.

unfortunately not what I want/need


Thanks in advance
