Note: Simultaneously press Ctrl and C to exit the ping command.
Example: Input ping 172.6.22.131 –l 1472 –f.
4. Verify the switch is not flow control.
Check the brand, model of the switch connecting IPC and NVR, and contact with the manufacturer of the switch
to check if it has the function of flow control. If so, please turn it down.
5. Check if the fault is solved by the step 1 to step 4.
If it is solved, finish the process.
If not, please contact the engineer from our manufacturer to do the further process.
 No monitor connected with the NVR locally and when you manage the IPC to connect with the device by
web browser remotely, of which the status displays as Connected. 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 > Configuration > Live View > View”, and select video output interface in the drop-down list and
configure the window you want to view.
Notes:
1) The view settings can only be configured 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, finish the process.
If not, please contact the engineer from our manufacturer 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 LAN port on a PC and the rear panel of NVR with an RJ45 LAN cable.
2) Go to the COMMAND screen (Start -> Run -> CMD -> Enter), and execute the ping command. 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
