How about a drone or roaming camera device set to take a single picture at a random number of seconds during its travels? Maybe a camera or two mounted on a garden train set?
Then the random time and the vagaries of travel would render a different image each time it did run.
And a camera mounted on a very tall pole (like an old TV antenna pole) looking down at the yard or out toward the horizon.
I wouldn’t rule out the ring doorbell cam either… Even though that is the wrong answer! I’d consider those ‘run of the mill’ devices as supplemental images of interest that could be deleted if boring.
You might find some inspiration from this website https://yellowcottagehomestead.com/
They have placed cameras all over their place watching the chickens, ducks, and cats around their homestead. David is a good source for a bit of technical help also.
Finally, I’m not sure what your goals are for this but, I’d look at the NASA sites for images from the International Space Station and maybe a few ‘winter’ images from the three Antarctica Expedition Observatories to give an interesting mix. Nothing like a snow scene in August.
