Driveway Probe vs a Camera
A probe tells you a vehicle came. A camera tells you which one.

Why this comes up
A probe tells you a vehicle came. A camera tells you which one. Start with the probe if you only need the chime. Add a camera at the gate if you need the picture.
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 alarm when that is the job in front of you. Start with the probe if you only need the chime. Add a camera at the gate if you need the picture.
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.
