Seeing a car loitering off the end of our driveway, on a shared gravel driveway. I want to put in a security light to discourage this.
PIR sensors will not work well because they use heat, and a car body may be pretty much at ambient temperature. I have often driven up to our garage, which has one, and it doesn't trigger until I get out of the car (showing my warm face and body).
I want all of the equipment to be on our property.
