I want to know if someone is trying to sneak up to my house and it's unlikely they would drive up.

Check out the Optex wireless 2000. Believe me, I've went through 1/2 doz brands and these are hands down the best for detection and range. Everything from photoelectric beams with trans/ receiver aligned , microwaves and pir ( passive infrared). If you want to just detect a car coming up your driveway or activate a gate to exit , the buried magnetic sensor works great, but the optex will do that too.
