b) The installed HDD has not been initialized.
c) The installed HDD is not compatible with the NVR or is broken-down.
Steps
1. Verify at least one HDD is installed in the NVR.
1) If not, please install the compatible HDD.
Note:
Please refer to the “Quick Operation Guide” for the HDD installation steps.
2) If you don’t want to install a HDD, select “Configuration > Remote Configuration >Exceptions”, and
uncheck the Audible Warning checkbox of “HDD Error”.
2. Verify the HDD is initialized.
1) Select “Configuration> Remote Configuration >HDD Management>Basic Settings”.
2) If the status of the HDD is “Uninitialized”, please check the checkbox of corresponding HDD and click
the “Format” button.
3. Verify the HDD is detected or is in good condition.
1) Select “Configuration > Remote Configuration >HDD Management>Basic Settings”.
2) If the HDD is not detected or the status is “Abnormal”, please replace the dedicated HDD according to
the requirement.

The status of the added IPC displays as “Disconnected” when it is connected through Hikvision Protocol.
Select “Menu>Camera>Camera>IP Camera” to get the camera status.

c) Insufficient bandwidth.
Steps

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 “Configuration> Remote Configuration >Camera Management>IP Camera”.

address, protocol, management port, user name and password.

4. Check if the fault is solved by the above steps.
If it is solved, finish the process.
If not, please contact the engineer from Hikvision to do the further process.
