GPS Angel’s new V4 Red Light Camera and Speed Camera warning system features an integrated rechargeable lithiumion battery option. The compact, cordless device uses advanced SiRF Star III GPS satellite technology to map the vehicle’s current position against an onboard database of more than 6,000 known red light camera and speed camera locations. When approaching one of these high-risk intersections, GPS Angel will automatically alert the driver through a series of visual and audible alerts. Offers unlimited free access to the database — simply plug the USB cord into your PC and download the updates from the Internet.
