We live on a corner lot and have quite a bit of foot traffic crossing our front yard. We have also had a problem with people checking car doors at night. 
I got this spotlight to deter people from walking in our yard and it’s making a big difference. I’ve noticed that most will divert to the sidewalk when they trigger the spotlight and keep farther from the house. 
The motion detector reaches out to 25 feet and puts out a good stream of light. I like that I can angle the two spots separately to get the best coverage. 
Highly recommended.
