4-channel MDVR Vehicle Mobile DVR

Model : DF-9804-4H-4G
Summarize : MDVR (Mobile Digital Video Recorders), commonly known as on-board DVR, is a device that uses advanced video and audio encoding and decoding technology to perform digital-to-analog conversion of videos inside and outside the vehicle and carry out compression and storage. It is widely applied in public operations, rail transportation, government law enforcement, shipping, public safety, school buses, intelligent driving, and other fields to improve driving safety, strengthen fleet operation management and realize real-time monitoring inside and outside the vehicle.

Product Description

Product Features

MDVR H.264 encoding format: high compression ratio, clear images, and low disk space occupation;
Advanced Driving Assistance System (ADAS): early warning of vehicle driving collisions, track deviations, pedestrian detection, and overspee, thus enhancing driving safety;
Blind Spot Detection system(BSD): early warning of other vehicles or obstacles in the driving blind area during vehicle turning and changing lanes to avoid collisions;
Driver Monitoring System (DMS): early warning of drivers' identity recognition, fatigue, and dangerous driving behaviors to increase driving safety and effectively manage the fleets;
Aviation video interface with high reliability and strong seismic resistance;
UPS power-off protection technology can still work for 3-5 seconds under the cut-off of the external power supply, preventing the accidental damage of video files;
