Why can’t I find the HDD?
a.
Please check the power and SATA data cables of the HDD to make sure they are well
connected.

For some NVRs with the 1U or small 1U case, the power of the adapter may be not
enough for operating them. Please use the power adaptor supplied along with the NVR.

Please make sure the HDDs are compatible with the NVR. See Appendix C Compatible
Device List for details.

The HDD could have gone bad. Change a new one.

properly and the network parameters are set correctly.

Q3.
The screen has no output after booting the NVR normally.

than 1280*1024, and then the screen will remind you that the screen resolution is not supported
by the NVR or just have no display. Please change a screen at 1280*1024, 1920*1080 or

Q5.
The NVR cannot add up to the maximum number of IP cameras?
Take the 16 CH NVR as an example. Some 16 CH NVR support a maximum of 120Mbps
bandwidth input (please take the real device for standard). Refer to the picture below. The
remaining bandwidth should be larger than the bandwidth of the IP camera you want to add, or
you would fail to add the IP camera. You should lower the added cameras’ bitrate to release the
bandwidth. It is recommended to add cameras by “Quickly Add” for batch adding.
