Mobile Digital Video Recorder

1. Overview

MDVR (Mobile Digital Video Recorder) MDVR is a 3G mobile-DVR intelligent computer terminals that designed for bus video surveillance, fleet scheduling and management of a multi-functional, highly interactive and strong scalable. MDVR has two high-performance processors of total have 6-core in the two CPUs and built-in 3D graphics. MDVR use embedded Linux operating systems.

Combined with the most advanced IT field technology, include H.264 video compression / decompression technology, 3G network technology, GPS positioning technology. MDVR can achieve 16-channel full real-time 960H format (and below) and Four 1080P/720P IPCs video record, preview, playback, network transmission, with the central server software and mobile client APP software, MDVR can realize central monitoring, playback, analysis, remote management and alarm trigger.

MDVR built-in passenger counting, voice announcer, media player, VoIP Internet telephony, advertising, driving records and other smart DVR functions. MDVR is modular in design, with high reliability, flexible installation, and easy maintenance.

All of these functions are integrated in a 7-inch LCD touch screen with two-DIN (2- DIN) box, MDVR can be very easily installed in the dashboard and maintain, it also easy to drivers to watch a variety of information and operate MDVR.
