We have a bunch of these outside and we've been watching the cats, possums, raccoons, and even turkeys frolic as they cross through our property. We even set up a little victorian style dog hours with solar panels in the backyard and the wild animals have been using it to rest. We have a ton of video of these little animals just relaxing and stretching out in the dog house too. The family loves it, every morning we get to see what the critters were up to.
Before that we were doing hydroponics and we had cameras on the fruits, the instruments for things like ph, ec, and a camera in the reservoir so we could monitor water levels.
I don't use them to watch my home, but they have been pretty solid in terms of watching other things that aren't security related or sensitive.
