Why would you do this?
I live out side of town. I want to know if someone drives to my house. I connected a light beam across the road to detect a car in front of the house. A car makes a very short "ding" of the door bell. Then 30 seconds later a person will ring the bell.Need opinion on wiring up trip beams to a door bell inside house

My problem is:
1) In very bright sunlight the project does not work.
2) At night it works too well when a deer or elk walk through the yard.
My Chinese manual calls the light beam a "break beam trip alarm". And it is wired up to my door bell.Need opinion on wiring up trip beams to a door bell inside house
