Problems
Solutions
1.
What is the maximum bit rate of the HS-1300?
Depending on the purpose of use, the device’s
maximum bit rate varies:
Record-Only: 16 Mbps
Stream-Only: 10 Mbps
Stream and Record: sum of the two video
bitrates should not exceed 12Mbps
2.
What are the appropriate SD card classes?
Use any of the SD Card Classes C10/U1/V10.
3.
a. Why am I still seeing lag delay in the video
recorded on SD Card Class C10?
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/form
atter_4/index.html).
b. In this case, why doesn’t the system issue
any error messages as soon as video recording
is started?
b. The system detects and sets the write speed
as soon as the video recording is started and
insufficient write speed is experienced while
the video is being recorded.
4.
Why am I seeing blurry images while the video
is being streamed over the RTSP protocol?
1. The maximum streaming resolution offered
on the NVS-31 is 1080p60 so try viewing the
streamed video on another computer.
2. Change your video source to 1080i (the
switcher output) and lower the bitrate.
3. This could be due to insufficient network
capacity. Use a Gigabit switch or router.
5.
The recorded video file cannot be played if
recording is stopped due to system crash or
power failure.
This is the limitation of MP4 files, which cannot
be played as long as the recording is stopped
incorrectly. It is recommended to use other
video formats to record or repair the file using
certain software tools.
