Yes there are smart refrigerators – but they can be costly. This fridge cam will only be approximately $200 and what it does!
It keeps track of everything in the fridge, so that from a distance you can tell what you have and what you need. If you’re connected to an electronic grocery store it can be ordered (I wonder if that can be automated and it could be seemlesly dilivered to you). Otherwise it will remind you of what you are low on. According to what you have in can suggest recipes. It monitors the temperature (that doesn’t seem so critical on a normal day – but then again). It keeps track of expiry dates.
Wow! Busy little camera isn’t it!
