1.2 MDVR PRODUCT APPLICATION CONNECTION SCHEMATIC DIAGRAM
Figure
1-1, MDVR can be used both in common and special vehicles video monitoring or remote
monitoring such as bus , logistics car , freight car , long-distance travel bus , taxi , tanker, school bus ,
police car , patrol car etc . Front end acquires signal by on-board special camera , through special video
line transfer it to MDVR mainframe to process video compression , local store in SD card. Model with
3G module can realize remote monitoring, recording, upload etc. Model with GPS function can realize
real time vehicle positioning; Schematic diagram is a common application mode, the actual use of
various functions will be changed as the existence of the modules change.
