MDVR (Mobile Digital Video Recorder) is the core hardware of IoV active safety systems, widely deployed on passenger, freight, bus and school bus fleets. It encodes, stores and uploads camera footage for real-time remote monitoring. Mainstream MDVRs support H.265 encoding, saving about 50% storage and bandwidth versus H.264, enabling multi-channel 1080P recording with 4G/5G live preview and cloud playback. New-generation MDVRs integrate AI for on-device ADAS, DSM fatigue detection and blind-spot analysis with sub-second local response that keeps working offline. Key selection factors: channel count (4CH/8CH), H.265 and 5G support, protocol compliance with JT/T 808 and GB/T 28181, and rugged wide-voltage shock-proof design. Huayao Tech MDVR series covers 4CH-8CH configurations, deployed with its IoV platform across passenger transport, hazmat, dump truck and school bus scenarios.
