Frequently-Asked Questions
Solutions
It is normal that audio is switched after the transition
is complete regardless of the transition method (T-
Bar or Auto) used.
Use any of the SD Card Classes C10/U1/V10.
a. This could be due to unoptimized disk formatting.
Format your disk on the NVS-31 or using the tool
downloaded from the SD association's official website
(https://www.sdcard.org/cht/downloads/formatter_
4/index.html).
b. The system only detects and sets write speed upon
start of video recording. The system will not issue an
error message if insufficient write speed is
experienced while video recording is in progress.
Please make sure the input and output are set to the
same resolution and frame rate.
Because the NVS-31 UI is not updated in real time so
the UI status display may not reflect the current
device status.
As a result, whether the device is operated on the
panel, on the UI or both, please refresh the status
page from time to time to make sure the information
shown is the latest. You should also constantly
monitor your video recording and streaming at the
same time.
