The VIDEO4 + GPS 4 camera package combines everything you will need to to record a perfectly synchronised data and video feed.
The VIDEO4 + GPS system features an internal 5Hz GPS reciever with integrated 2g accelerometers, all with full frame by frame video synchronisation. The GPS and accelerometers provide speed, position, lap timing and grip usage (g force) information.
This data can be used alongside the video for detailed analysis in the software, and/or overlaid graphically to create a video/DVD/YouTube video.
