The GPS Angel V4 is a red light camera and speed camera warning system that you place on your car's dashboard. It uses GPS to figure out where your car is and maps that against the built-in database of over 6000 known red light camera and speed camera locations, and warns you when you're approaching one.
There are no monthly fees to keep the database up-to-date. Just plug it into your PC via a USB cable. You can also search the list online at www.gpsangel.com.
One other nice feature is the ability to program the V4 to warn you when you are in school zones, parks, etc.
