A: Please set a lower sub-stream to transmit images. When the sub-stream is set too high, block or slower
transmission rate may result due to upload limit of the network; the video transmission may be seriously
affected due to weak network signal or intermittence.
Q: the device normally reports information to the CMS while video cannot be displayed after a period of
time?
A: Firstly, check if the device information displays dial-up. If yes, the traffic for the SIM card may be used
up. Please replace with a new one for test; secondly, check if the device number is tampered. If yes, your
vehicle information shall be reported again to the server; thirdly, if card replacement cannot still solve this
problem, check if the device 3G module is faulty.
