Opening the door wastes energy. And it seems, mindlessly going to the fridge to see what's inside even though you know exactly whats inside, is a thing many people are doing. So there is an argument to be made, that a camera in the fridge is a useful feature. I'm happy without it.

You could get a glass door fridge?

That probably wastes more electricity; heat insulators and clear substances don't overlap very much.

If the budget for the cameras, screens and apps would be spend on extra isolation, the fridge would overall be more ecological. But hey. I understand. Gadgets sell more than quality.

If you want a fridge that’s really efficient, you can’t beat a chest/bunker freezer with a thermostat. Refrigerators lose all their efficiency from the vertically mounted doors which allow all the cold air to fall out instantly when you open the door. A chest freezer door is mounted horizontally so the cold air stays trapped inside, even when you open the door. This makes all the difference in the world!

Is that more heat waste than the habit of constantly closing and opening the door to check what's inside?

I don't have the ability to experimentally verify, but I would think so? A window is going to be there 24/7 and air doesn't actually have that high of a specific heat, so you'd really have to be constantly opening the door for it to come out in favor in my understanding.
