Specification:
MDVR is a cost-effective and functionally expandable equipment
designed for video surveillance and remote monitoring in cars,
trains and other vehicles. It uses a high-speed processor and
an embedded Linux platform, in combination with the state-of-the-art H.264 video
compression/decompression technology in the IT field. With SD card/hard disk as a storage medium, MDVR is capable of 4-channel audio and video recording and driving information recording in formats of CIF, HD1 and D1. MDVR is characterized by simple appearance, superior vibration-proof performance, flexible and easy installation, powerful functions and high reliability.
