how to participate

Surveillance under Surveillance uses data from OpenStreetMap contributors that is not visualized on the regular OpenStreetMap site. If you like to add new cameras or guards or if you like to revise existing entries use your existing OSM account or create a new one.

Our database is updated once an hour. So it might take a while until your OSM entries are visible on the Surveillance under Surveillance map.
