Building new at a site with great across the street neighbor who has offered to let me put up a webcam to record construction. He said I can connect to his power and/or wifi (but no wired ethernet possible).

What is the best product for this? Hopefully it can be done with a single camera. In order to get a proper view, without being blocked by the trees in his yard, I need to put it up OUTSIDE, probably on his fence. Thus there is some chance of theft, so don't want something too expensive. Ideally it would be something that takes a pic every 10 minutes or so during the day. I am not interested in something that takes a pic every time there is motion (constant traffic or cars or people). I can't put it up at my own site because it will be awhile before there is power (lots of grading & sitework first).

Have you tried looking into trail cameras?

#1, they're battery-operated, so no power onsite shouldn't be an issue. They're usually intended for use out in a field somewhere.

#2, you can get the kind with night-vision, so that there's no flash for night shots that would betray the camera's location.

#3, out in the field, you have a lot of leaves and things that are in constant motion. Some of the trail cameras are triggered by body temperature combined with motion. I don't know if the temperature of a vehicle would trigger it, but if you could put it on your property and angle it to minimize the street coverage, you might look into that.
