Possible suspicious behavior

I just wanted to give the neighborhood a heads up on some suspicious behavior. Today around 11:30 I saw a new, grey Hyundai or Honda hatchback parked in the bike lane, I assumed it was an amazon delivery guy and was going to remind them not to park in the bike lane but then I saw it was actually a middle aged, slightly overweight, white male taking a picture from my neighbors porch of the side of my house and maybe my neighbor’s house too. When I approached he quickly went back to his car and speed off, ignoring me. We have some construction going on so I don’t know if he was casing the site and interested in the workers tools. Besides trespassing and being creepy, it didn’t seem definitive enough to call the police but I wanted to mention it here in case it becomes a reoccurring thing.
