Q:
Why the vehicle and video cannot be seen in SVC420/820GPS-L 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 modules or via WIFI. If via built-in 3G, please check whether selected the
correct type of built-in 3G modules, for example WCDMA and EVDO module needs the
support from corresponding SIM cards. Check whether the antenna is in good contact. If it
still cannot report when all above are checked, enter into the system information page to
view the dial-up. If dial-up is not successful, look up whether the setting of data access point
and center number is correct. If all this fails, please collect as much information as possible
to submit to the technical support staff for analysis. The more data provided, the easier it
will be for the 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 SVC420/820GPS-L, 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 driver has modified the host device number. The host with a 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 module fails.
