2) Open the Super Terminal, use the ping command and keep sending large data packages to the
connected IPC, and check if there exists packet loss.
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 HDVR, 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 company to do the further process.

When there is no monitor connected to the HDVR and you add the IPC via web browser, the IPC status
shows as Connected; and then you connect the HDVR with the monitor via VGA or HDMI interface and
reboot the device, there is black screen with the mouse cursor.
Connect the HDVR 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 Connected. And then connect
the device with the CVBS, and there is black screen either.
Possible Reasons:
After connecting the IPC to the HDVR, 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 HDVR.
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 company to do the further process.

Live view stuck when video outputs locally.
Possible Reasons:
a) Poor network between device and IPC, and there exists packet loss during the transmission.
b) The frame rate has not reached the real-time frame rate.
Steps:
1. Verify the network between device and IPC is connected.
1) When image is stuck, connect the RS-232 ports on PC and the rear panel of device 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 (Continuous) 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 (Continuous).
3. Verify the frame rate is real-time frame rate.
