I love mine. I have a 30X and a 25X. Seeing how far away the street is from your home, a 25X should do nicely unless you want to read their tire size, too. Then I would spring for the 30X.
I dunno man, seems like a good way to get shot. I'm assuming this is a public access road? If it is, you don't really have authority to be running people off regardless of whether they're taking a leak and littering or not. Then you show up with a flash light in their face and a gun in hand? Looks like you didn't even notice there was another person in the back seat that whole time. You'd be dead if these were bad guys and not just idiots who needed to piss. Maybe there's more to it that I don't know about, but I'd re-evaluate your approach.
Don't get me wrong. I understand the frustration. I spend more time than I'd like running drunk college kids off of my boat dock, but it's a bit different dealing with kids from a distance who obviously aren't armed than what this video shows.
30X is a discontinued HIKVISION DS-2DE7530IW-AE Turret. I have had it up and running 24/7 for about 4 years. Still going strong with zero issues.
25X is a HIKVISION DS-2DE4A425IW-DE Got this one this summer. Yep, it's a dome PTZ, but I really haven't had any issues with clarity or IR backfeed into the optics. I bought it mainly for watching wildlife in my backyard and woods surrounding my house. My house is a 1/3 mile off the road. Don't get any human visitors back here, except my grand daughter on her mini bike.
