Motion Sensor for a Barn Lot
Barn lots have animals, which means false alarms.

Why this comes up
Barn lots have animals, which means false alarms. A magnetic probe in the lane ignores deer better than a wide motion light.
What to check on the map first
County GIS lines are assessment maps. They are not a survey, and a product will not redraw them.
Open Platbookmapper and choose the state. The directory sends you to the county viewer. Match the parcel ID before you trust a pin on an aerial photo.
A tool that matches the job
Shop the Driveway sensor probe when that is the job in front of you. A magnetic probe in the lane ignores deer better than a wide motion light.
The limit
Put the sensor on your lane or your door. A chime is not a boundary, and a shared easement is only a right to pass.
The county viewer is the map. The product is only the tool you carry.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
