FAQ

No image displayed on the monitor after
starting up normally.
Possible Reasons
a) No VGA or HDMI connections.
b) Connection cable is damaged.
c) Input mode of the monitor is incorrect.
Steps
1. Verify the device is connected to the
monitor via HDMI or VGA cable.
If not, please connect the device with the
monitor and reboot.
2. Verify the connection cable is good.
If there is still no image display on the
monitor after rebooting, please check if the
connection cable is good, and change a cable
to connect again.
3. Verify Input mode of the monitor is
correct.
Please check the input mode of the monitor
matches with the output mode of the device
(e.g. if the output mode of NVR is HDMI
output, then the input mode of monitor
must be the HDMI input). And if not, please
modify the input mode of monitor.
4. Check if the fault is solved by the step 1
to step 3.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.
There is an audible warning sound “Di-Di-
Di-DiDi” after a new bought NVR starts up.
Possible Reasons
a) No HDD is installed in the device.
b) The installed HDD has not been
initialized.
c) The installed HDD is not compatible
with the NVR or is broken-down.
Steps
1. Verify at least one HDD is installed in
the NVR.
1) If not, please install the compatible
HDD.
Note: Please refer to the “Quick
Operation Guide” for the HDD
installation steps.
2) If you don’t want to install a HDD,
select “Menu>Conguration >
Exceptions”, and uncheck the Audible
Warning checkbox of “HDD Error”.
2. Verify the HDD is initialized.
1) Select “Menu>HDD>General”.
2) If the status of the HDD is
“Uninitialized”, please check the
checkbox of corresponding HDD and
click the “Init” button.
3. Verify the HDD is detected or is in good
condition.
1) Select “Menu>HDD>General”.
2) If the HDD is not detected or the
status is “Abnormal”, please replace
the dedicated HDD according to the
requirement.
4. Check if the fault is solved by the step
1 to step 3.
1) If it is solved, nish the process.
2) If not, please contact the engineer to do
the further process.
The status of the added IPC displays
as “Disconnected” when it is connected
through Private Protocol. Select
“Menu>Camera>Camera>IP Camera” to
get the camera status.
Possible Reasons
a) Network failure, and the NVR and IPC
lost connections.
b) The congured parameters are incorrect
when adding the IPC.
c) Insufcient bandwidth.
Steps
1. Verify the network is connected.
1) Connect the NVR and PC with the RS-
232 cable.
2) Open the Super Terminal software, and
execute the ping command. Input “ping
IP” (e.g. ping 172.6.22.131).
Note: Simultaneously press Ctrl and C
to exit the ping command.
If there exists return information and
the time value is little, the network is
normal.
2. Verify the conguration parameters are
correct.
1) Select “Menu>Camera>Camera>IP
Camera”.
2) Verify the following parameters are the
same with those of the connected IP
devices, including IP address, protocol,
management port, user name and
password.
3. Verify the whether the bandwidth is
enough.
1) Select “Menu >Maintenance > Net
Detect > Network Stat.”.
2) Check the usage of the access
bandwidth, and see if the total
bandwidth has reached its limit.
4. Check if the fault is solved by the step 1
to step 3.
If it is solved, nish the process.
If not, please contact the engineer to do the
further process.
The IPC frequently goes online and
ofine and the status of it displays as
“Disconnected”.
Possible Reasons
a) The IPC and the NVR versions are not
compatible.
b) Unstable power supply of IPC.
c) Unstable network between IPC and
NVR.
d) Limited ow by the switch connected
with IPC and NVR.
Steps
1. Verify the IPC and the NVR versions are
compatible.
1) Enter the IPC Management interface
“Menu > Camera > Camera>IP
Camera”, and view the rmware version
of connected IPC.
2) Enter the System Info interface
“Menu>Maintenance>System
Info>Device Info”, and view the
rmware version of NVR.
2. Verify power supply of IPC is stable.
1) Verify the power indicator is normal.
2) When the IPC is ofine, please try the
ping command on PC to check if the PC
connects with the IPC.
3. Verify the network between IPC and NVR
is stable.
1) When the IPC is ofine, connect PC and
NVR with the RS-232 cable.
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 ow 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 ow 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, nish the process.
If not, please contact the engineer 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.
