however, there are some mountainous districts without signal coverage, and some suburban areas
have weak signal due to the local network constraints, then it will be jammed during watching of video,
or video cannot be watched at all, the greatest impact of this situation is from the local network.
Moreover check whether the frame rate setting of sub-stream is too high, because the video may also
occur such situation when the network is poor and frame rate setting is high.
Q: Why the vehicle and video cannot be seen in CMSServer client when the device has been started?
A: At first make sure the central registration server is switched on and on the net, then check whether
the host device number has been occupied to cause conflict, secondly check whether the settings of
server-centric IP and port are correct. devices report to the center via the built-in 3G/4G module or via
WIFI. If via built-in 3G/4G, please check whether selected the correct type of built-in 3G/4G module, for
example, WCDMA and EVDO module needs the support from corresponding SIM card, check whether
the antenna is in good contact. If it still can not report when above all are checked, enter into the
system information page to view dial-up. If dial-up is not successful, look up whether the setting of data
access point and center number is correct. If all ultimately fail, please collect as much information as
possible to submit to the technical supporting staff for analysis, the more data provided, the more
convenient for technicians to solve the problem.
Q: The device is online, but why can I not see the video image?
A: Please set lower sub-stream to transmit image, the blocked or slow transmission speed situation
may occur when the sub-stream frame rate is set very high and be affected by network uploading limit.
poor network signal or intermittent will seriously affect the video transmission.
Q: The device is properly reported on CMSServer, but the videos cannot be seen after using for some
time?
A: Firstly check whether the host side displays dialing, if it keeps the dialing status, it may be because
the flow of the SIM card has run out, replace the SIM card to test. Secondly query whether the
host device number has been modified by the driver, the host with modified device number needs
to be resubmitted to add vehicle information. thirdly, if it still does not work by changing the card, it
will need to check whether the host's 3G/4G module fails.
