Register any camera you already own. Neighbors and law enforcement see that coverage exists — never the footage itself, unless you approve that specific clip, for that specific request.
Register what you actually have — no new hardware required. Set the camera type, a short description, and where it's pointed.

Set which way a camera faces and how wide its view is, and tag what it covers — front door, driveway, backyard, alley. Neighbors see coverage density on a map. They don't see your street number.
No one ever gets standing access to your camera. A clip request comes in tied to a specific incident, you approve or deny it — with a note if you want — and that's the only footage that ever leaves your device.
This is a coordination tool for after something happens — not a surveillance network.
