The MVR9004-3G is a digital video recorder designed for all mobile applications that include ground, air, and sea. Our latest innovative design far exceeds current industry specifications. Its embedded GPS enables the ability to identify a vehicle's position with superior accuracy and is accessible through the DVR's integration with Google Maps and its own Central Vehicle Management Software (CVMS ). Built-in shock absorbers prevent damage done by vibration and protects the recorder and its internal components while in motion.
