And then you connect the device with the
monitor via VGA or HDMI interface and
reboot the device, there is black screen with
the mouse cursor.
Connect the NVR with the monitor before
startup via VGA or HDMI interface, and
manage the IPC to connect with the device
locally or remotely, the status of IPC
displays as Connect. And then connect the
device with the CVBS, and there is black
screen either.
Possible Reasons:
After connecting the IPC to the NVR, the image
is output via the main spot interface by default.
Steps:
1. Enable the output channel.
2. Select “Menu > Conguration > Live View
> View”, and select video output interface in
the drop-down list and congure the window
you want to view.
Notes:
1) The view settings can only be
congured by the local operation of
NVR.
2) Different camera orders and window-
division modes can be set for different
output interfaces separately, and digits
like “D1”and “D2” stands for the
channel number, and “X” means the
selected window has no image output.
3. Check if the fault is solved by the above
steps.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.

Live view stuck when video output locally.
Possible Reasons:
a) Poor network between NVR and IPC,
and there exists packet loss during the
transmission.
b) The motion detection and alarm
functions are enabled, and the
parameters of Main Stream (Normal)
and Main Stream (Event) are different.
So the image looks stuck due to the
image changes between different
resolutions.
c) The frame rate has not reached the real-
time frame rate.
Steps:
1. Verify the network between NVR and IPC
is connected.
1) When image is stuck, connect the RS-
232 ports on PC and the rear panel of
NVR with the RS-232 cable.
2) Open the Super Terminal, and execute
the command of “ping 192.168.0.0 –l
1472 –f” (the IP address may change
according to the real condition), and
check if there exists packet loss.
Note: Simultaneously press Ctrl and C
to exit the ping command.
2. Check the parameters of Main Stream
(Normal) and Main Stream (Event).
Select “Menu > Record > Parameters >
Record”, and set the resolution of Main
Stream (Event) the same as the one of Main
Stream (Normal).
3. Verify the frame rate is real-time frame
rate.
Select “Menu > Record > Parameters >
Record”, and set the Frame rate to Full Frame.
4. Check if the fault is solved by the above
steps.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.

Live view stuck when video output remotely
via the Internet Explorer or platform
software.
Possible Reasons:
a) Poor network between NVR and IPC,
and there exists packet loss during the
transmission.
b) Poor network between NVR and PC,
and there exists packet loss during the
transmission.
c) The performances of hardware are not
good enough, including CPU, memory,
etc..
Steps:
1. Verify the network between NVR and IPC
is connected.
1) When image is stuck, connect the RS-
232 ports on PC and the rear panel of
NVR with the RS-232 cable.
2) Open the Super Terminal, and execute
the command of “ping 192.168.0.0 –l
1472 –f” (the IP address may change
according to the real condition), and
check if there exists packet loss.
Note: Simultaneously press Ctrl and C to exit the
ping command.
2. Verify the network between NVR and PC
is connected.
1) Open the cmd window in the Start
menu, or you can press “windows+R”
shortcut key to open it.
2) Use the ping command to send large
packet to the NVR, execute the
command of “ping 192.168.0.0 –l
1472 –f” (the IP address may change
according to the real condition), and
check if there exists packet loss.
Note: Simultaneously press Ctrl and C
to exit the ping command.
3. Verify the hardware of the PC is good
enough.
Simultaneously press Ctrl, Alt and Delete to
enter the windows task management interface,
as shown in the following gure.
Windows task management interface

Select the “Performance” tab; check
the status of the CPU and Memory.

If the resource is not enough, please
end some unnecessary processes.
4. Check if the fault is solved by the above
steps.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.

When using the NVR to get the live view
audio, there is no sound or there is too much
noise, or the volume is too low.
Possible Reasons:
a) Cable between the pickup and IPC is not
connected well; impedance mismatches or
incompatible.
b) The stream type is not set as “Video &
Audio”.
c) The encoding standard is not supported
with NVR.
Steps:
1. Verify the cable between the pickup and
IPC is connected well; impedance matches
and compatible.
Log in the IPC directly, and turn the audio on,
check if the sound is normal. If not, please
contact the manufacturer of the IPC.
2. Verify the setting parameters are correct.
Select “Menu > Record > Parameters >
Record”, and set the Stream Type as “Audio
& Video”.
3. Verify the audio encoding standard of the
IPC is supported by the NVR.
NVR supports G722.1 and G711 standards,
and if the encoding parameter of the input
audio is not one of the previous two standards,
you can log in the IPC to congure it to the
supported standard.
4. Check if the fault is solved by the above
steps.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.

The image gets stuck when NVR is playing
back by single or multi-channel.
Possible Reasons:
a) Poor network between NVR and IPC,
and there exists packet loss during the
