Solution:
1. Verify the network is connected.
Connect the NVR and PC with the RS-232 cable.
Open the Super Terminal software, and execute the ping command. Input
“ping IP” (e.g., ping 172.6.22.131).
Note: Press Ctrl + 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.
Select Menu > Camera > Camera > IP Camera.
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 that there is enough bandwidth.
Select Menu > Maintenance > Net Detect > Network Stat..
Check if the access bandwidth has reached its limit.
4. Check steps 1 to 3 for resolution.
If it is solved, finish the process.
If not, 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:

The IPC and the NVR versions are not compatible

Unstable power supply of IPC

Unstable network between IPC and NVR

Limited flow by the switch connected with IPC and NVR
Solution:
1. Verify the IPC and the NVR versions are compatible.
Enter the IPC Management interface (Menu > Camera > Camera > IP
Camera), and view the firmware version of connected IPC.
Enter the System Info interface (Menu > Maintenance > System Info > Device
Info), and view the firmware version of NVR.
