Description
GeoAudio+ with built-in GPS receiver encodes GPS location, heading, speed, altitude,
date, and time into a continuous audio stream that can be recorded by off-the-shelf
camcorders and DVR (digital video recorder) systems. The encoded audio, automatically
synchronized with the camera video, translates into an exact, permanent record of when
and where the events in the video occurred.
GeoAudio+ decode mode is used during the video playback to convert the encoded audio
back into a GPS NMEA 0183 USB serial stream that can be used by most PC mapping
applications such as Google Earth.
GeoAudio+ includes a 6’ 3.5 mm male-to-male audio cable, 6’ USB A-Male to Mini-B cable,
Microsoft Windows USB driver and diagnostic application disc. 4 AA batteries are not included.
