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. The MVR9004-3G uses a 2.5 inch SATA or Solid State Drive which features faster data transfer speeds and less moving parts, making them more suitable for mobile applications. The device's GPRS (3G) transmission makes it ideal for wireless data transmission and is compatible with most data carriers. An optional 4G functionality is also available for improved data transmission.
