Vehicle DVR's Specifications
Mobile Digital Video Recorder(MDVR) is a equipment with high cost performance,strong function expandability,it’s designed for car video surveillance and remote monitoring.It uses high-speed processor and embedded Linux development platform, combined with the most advanced H.264 video compression / decompression technology,network technology and GPS positioning technology in the in the IT field. Using the SD card as storage media, MDVR can achieve 4 CIF, HD1 and D1 format audio video, car driving information record and upload GPS positioning signals. MDVR is compatible with center software that can be realized with the linkage of the central alarm monitoring, remote management and playback analysis. MDVR looks simple, the features with superior shakeproof, installation flexibility, powerful, and high reliability.
