Motion Sensor for an Alley Side
An alley or an unopened alley is a second entrance.

Why this comes up
An alley or an unopened alley is a second entrance. Light your gate on the alley. Confirm the alley is not someone else's access only.
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 Motion sensor light when that is the job in front of you. Light your gate on the alley. Confirm the alley is not someone else's access only.
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.
Walk the parcel in daylight before you trust a gadget at dusk.
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.
