The DVR (Automotive) is a cost-effective, functional and scalable device designed for video surveillance and remote monitoring of your mobile assets. It uses a high-speed processor, an embedded Linux platform and combines the most advanced IT processes such as H.264 Video Compression/Decompression, 3G and GPS positioning technology. MDVR enables CIF, HD1 and D1 video formats. Drivers' driving information, recording and wireless data are uploaded to HDD or SD Memory Cards which are used as the storage medium. A DVR centric software platform (CMS) can be realized with links to a Central Alarm monitoring system for remote management and playback analysis. The DVR may look simple in its exterior design, provides powerful auto black box features, installation flexibility and high reliability.
