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 configured parameters are incorrect when adding the IPC.
c) Insufficient bandwidth.
Steps
1. Verify the network is connected.
1) Connect the NVR and PC with an RJ45 cable.
2) Go to the COMMAND screen (Start -> Run -> CMD -> Enter), and execute the ping command. Input “ping
IP” (e.g. ping 172.6.22.131 if this is the IP address of the NVR). The screen will report if there is a reply from
the IP address.
Note: Simultaneously press Ctrl and C to exit the ping command. Or, type “Exit” and then hit Enter
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 from our manufacturer 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 LAN cable.
2) Go to the COMMAND screen (Start -> Run -> CMD -> Enter), and execute the ping command. Use the ping
command and keep sending large data packages to the connected IPC, and check if there exists packet loss.
