Tent for hunting with a camera gun WANTED

[GPS]

There are other issues than just the cold. If the blind is relatively closed, the condense from your breath will inevitably cover whatever camera system you have inside - the tripod, the lens, metal parts etc. If you want to breath inside for a day you will encounter this problem.
Each winter I sleep for some individual nights in nature, on snow, with no tent, no sleeping bag (Norwegian army style), at high altitudes, -12°C is no problem. In the morning I take pictures but the equipment is never inside a tent. It seems to me that you would need a double room blind but even so the condense problem will be serious.

The hunting type blinds tend to have enough windows to see/shoot out of that condensation isnt a problem in practice.

Sleeping on snow with no sleeping bag? Ouch!

A nice try but I'm afraid it's just wish thinking. Before your breath has the chance to escape through the nice windows it will already freeze on the midway, i.e. on the most thermally conductive surface (the metal parts of you camera) it finds. In fact at those extreme temperatures even you eyebrows catch the condense before it had time to escape.
The best solution would be to have the blind heated (gas heaters?).
