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 configuration 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, finish the process.
If not, please contact the engineer to do the
further process.
The IPC frequently goes online and
offline 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 flow 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 firmware version
of connected IPC.
2) Enter the System Info interface
“Menu>Maintenance>System
Info>Device Info”, and view the
firmware version of NVR.
2. Verify power supply of IPC is stable.
1) Verify the power indicator is normal.
2) When the IPC is offline, 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 offline, 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 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 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.
