DeFlock

Crowdsourced tool for locating and reporting ALPRs. View Live Site.

Purpose

I created this project after noticing the mass deployment of ALPRs in cities, towns, and even rural areas in the recent years. It's a massive threat to privacy, and this projects helps shed a light on this issue as ALPRs continue to be deployed to thousands of cities across the US and possibly beyond.

What it Does

View ALPRs on a Map

Uses OpenStreetMap data to populate a map with crowdsourced locations of ALPRs, along with their type and direction they face.

Report ALPRs

Provides OSM tags for easy reporting of ALPRs based on brand on OSM's editing site. Evemtually, this will be a native feature of the site.

Learn About ALPRs

See photos of common ALPRs and learn about their capabilities.
