Watch Tower Pro maps 670,000+ publicly documented surveillance cameras worldwide — government CCTV, police license-plate readers (ALPR), speed and red-light enforcement, traffic monitoring, and dome cameras — and alerts you before you walk or drive into range. Most people pass a dozen cameras a day without noticing. Watch Tower Pro is a privacy-awareness tool: it shows you what's documented so you can make informed decisions about where you go and how you get there. WHAT'S NEW IN 1.4.2 - Refreshed worldwide database: 670,344 cameras, rebuilt across all seven continents and de-duplicated so no two entries share a location. - Wider detection of mapped cameras, especially speed, red-light and plate-reader sites. - Fixes to the camera-reporting screen and the Settings source list. WHAT IT DOES - Works completely offline. The entire worldwide database ships inside the app — no signal needed, no server to query. - Color-codes every camera by type so you can tell an ALPR from a traffic cam at a glance. - Optional proximity alerts: a local notification when you enter the range of an alert-eligible camera. Choose which types alert you and how close. - Travel mode widens coverage automatically when you're driving so alerts fire at highway speed. - Nearby list ranks every documented camera within 8 km by distance, with the operator where known. - Directions to any camera, plus a link to its public source record. WHAT IT DOESN'T DO - No accounts. No login. No analytics. No tracking. No ads. - Your location never leaves your device. Alerts use iOS region monitoring entirely on the phone. - We do not collect, store, or transmit any personal data. Camera reports are ordinary emails you send yourself. - We do not include residential cameras (Ring, Blink, Nest, etc.). Their locations aren't public, and aggregating them would be wrong. LIMITATIONS Public databases lag reality. A missing marker does not mean there's no camera there — treat all public space as observed. Reported cameras are reviewed by a person and added in the next data update, never posted automatically. DATA SOURCES Almost every location comes from OpenStreetMap (© OpenStreetMap contributors, ODbL), including the plate-reader locations, which are ordinary OpenStreetMap nodes. A smaller set comes from camera feeds published openly by government transportation agencies. Each camera's detail screen credits its source and links to the original record. Watch Tower Pro is informational, not legal advice. By using it you agree to use it for lawful, defensive privacy-awareness purposes only. Made by BlackFox Media LLC.
