"New for 2011. The Kronos DVR is both a video recording system and a laptimer unit. It's the perfect match for your motorsports activities! The 2.5" LCD screen will display your lap timing information in big, bold numbers that are easy to read while you are on the track, while also recording one channel of high resolution video (720x480 pixels).
Records using the highly popular H.264 codec, and playback on your computer or directly on the built-in screen. Review all of your videos with lap timing information directly in the pits, right after your track session. No need for a PC or to download anything, all your data is stored to a memory card (SD type)."
