Appendix 5: Frequently-Asked Questions

This section describes problems that you may encounter while using HS-1300. If you have any questions,
please refer to related sections and follow all suggested solutions. If problem still exists, please contact
your distributor or the service center.
No.
1. What is the maximum bit rate of the HS-1300?
2. What SD card classes do you recommend?
3. a. I've recorded video on SD Card Class C10 but
I am still seeing delay?
b. In this case, why doesn't the system issue
any error messages as soon as video recording
is started?
4. Why am I seeing blurry images while the video
is being streamed over the RTSP protocol?
5. The recorded video file cannot be played if
recording is stopped due to system crash or
power failure.
6 How to retrieve the device IP if I do not
remember the network settings or the
network settings are lost?
Problems
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
Please use 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/form
atter_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.
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.
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.
If you do not remember the IP address
assigned to the device, follow the steps below
to reset the network settings:
 Turn off the machine.
 Press the RECORD and STREAM buttons
simultaneously and switch ON the device.
 Wait for 5 seconds approximately and
release the button push as soon as the two
buttons light up.
 The default IP address is 192.168.1.60.
