2. Verify power supply of IPC is stable.
Verify the power indicator is normal.
When the IPC is offline, try the ping command on the PC to check if the PC
connects with the IPC.
3. Verify that the network between IPC and NVR is stable.
When the IPC is offline, connect PC and NVR with the RS-232 cable.
Open the Super Terminal, use the ping command, and keep sending large
data packages to the connected IPC. Check if there is a packet loss.
Note: Press Ctrl + C to exit the ping command.
Example:
Input ping 172.6.22.131 –l 1472 –f.
4. Verify that the switch is not flow control.
Check the brand, model of the switch connecting IPC and NVR, and contact
the switch manufacturer to check if it has the function of flow control. If so,
turn it down.
5. Check steps 1 to 4 for resolution.
If it is solved, finish the process.
If not, contact the engineer to do the further process.
Using the IPC to connect a device remotely, with no NVR monitor
connection, is successful. Using a monitor (VGA or HDMI) to connect
devices is unsuccessful, resulting in a blank screen with a mouse cursor.
Prior to startup, connect the NVR to the monitor using VGA or HDMI.
Connect the device, locally or remotely, using IPC. The result displays it is
connected, but there is a blank screen with a mouse cursor
Possible reasons:

After connecting the IPC to the NVR, the image output is the main spot
interface by default.
Solution:
1. Enable the output channel.
2. Select Menu > Configuration > Live View > View, select video output interface
in the drop-down list, and configure the window you want to view.
Note: The view settings are only configurable by local NVR operation.
Different camera orders and window-division modes is set for different output
interfaces. Digit “D1”and “D2” stands for the channel number, and “X” means
the selected window has no image output.
