It's a transparent map of known safety cameras (or speed cameras) within the UK and many parts of the world, based on the downloadable database service from PocketGPSWorld.com. It is designed to work with many of the older Garmin GPS mapping units which were available before the user-defined Points of Interest loader (POILoader) feature became available across the Garmin range.

There are currently over 11,100 verified cameras in the PocketGPSWorld database, as at July 2007. Most Garmin GPSRs will only allow up to 500 waypoints - some units even less. I used to cut down the database to around 450 cameras closest to where I live, then convert these to waypoints. This became quite a hassle every month, and my GPS units seemed to be noticeably slower when "full" of waypoints like this. So instead, I wrote some conversion software to convert the data into a POI map.
