Martel's new DVD Partner in-car digital video system will work for large and small agencies, no computer required. The DVD Partner records directly to a DVD that can be played on a regular DVD player. Because it’s a solid state mobile DVD video recording system, there are no hard drives to freeze or break. The unit is so advanced it records DVD files as the unit is recording, and you can burn DVDs while driving. You can record 8.5 hours on one regular DVD. The DVD Partner can record to DVD-R, DVD+R, DVD-RW, and DVD+RW.
