• The status of the added IP camera displays as “Disconnected” when it is connected through Private
Protocol. Select “Menu > Camera > Camera > IP Camera” to get the camera status.
Possible Reasons:
• Network failure, and the NVR and IP camera lost connections.
• T

• Insufficient bandwidth.
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 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 bandwidth is adequate.
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 steps 1 to 3. If it is solved, finish the process. If not, contact an engineer
from Hikvision for further processing.
