User Manual of DS-7100NI Series NVR
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.
Open the Command Prompt, 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 from Hikvision 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.
Open the Command Prompt, 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 from Hikvision 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. And then you connect the device with
