IMEI (International Mobile Equipment Identity) is the contracting of International Mobile Equipment Identity code
It writes, international mobile equipment identification code, " the electronics string number " being made of 15 bit digitals, it is corresponded with every mobile terminal,
And the code be the whole world have " uniqueness ".Specific Android client terminal is tied up by IMEI unique marks
It is fixed.
Implement having technical effect that for the device of the present embodiment two：
The information that the program is acquired in video acquisition unit is bound with Android client terminal, the source of information
With uniqueness, retrospective can be chased after, therefore ensure that the safety of information collection transmission.
Referring to Fig. 5, the embodiment of the present invention three, is used for the device 3 of motor vehicle real-time video monitoring, most big portion
Divide function module identical as embodiment one, the difference is that：Video information collecting unit 10 includes：The outer monitor camera of vehicle
101, interior monitor camera 102.
Implement having technical effect that for the device of the present embodiment three：
Video information collecting unit includes：The outer monitor camera of vehicle and interior monitor camera, for the letter of video acquisition
Breath is comprehensive, without dead angle, the information because obtained from more comprehensively, it is more acurrate, more reliable.
Please refer to Fig. 6, Fig. 7, Fig. 8, Fig. 9, a kind of system for motor vehicle real-time video monitoring, including vehicle-mounted client
