Driveway alarm?

Not sure if you searched the forum before posting, but there are several threads in this topic. This one mentions another:

Laser Sensor Driveway Monitor Device?

Is there some type of Laser Sensor that I can use to see if someone pulls into my drive way? I don’t really want a motion detector, but some type of other perimeter sensors for my drive way, and backend. Anyone have ideas?
