If I was going to install a sign that is the kind of sign that I would use. Most people that wonder up my driveway turn around when they see the cameras. The ones that don't turn around probably would not turn around because of a sign either. I don't mind people just coming up the driveway but it's more concerning when they enter the yard. If I'm home I can go out and confront them, and if I'm gone I can set off a siren with my phone to run them off. I have considered putting a siren at the end of the driveway that I could set off if I see somebody pissing
People wander up the driveway fairly often. Just yesterday I had a walker and a truck come by. I haven't checked my videos yet today to see what happened. I may have had more visitors but I know they didn't come too close because I didn't get a notification on my phone.
Honestly...regarding the gold Chevy pickup, when you play at normal speed, between 7:55:35 and :38, I see what appears to be a third person in the middle of the back seat, loading or holding a bright plated pistol. Of course, the windshield has a lot of reflections and it's probably my imagination....just sayin'.....
