Appendix A FAQ
Q1. 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.
b. 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.
c. Please make sure the HDDs are compatible with the NVR. See Appendix C Compatible
Device List for details.
d. The HDD could have gone bad.
Q2. Why are there no images output in some or all of the camera windows?
a. Please make sure the resolutions of the cameras are supported by the NVR.
b. Please make sure the network cables of the IP camera and NVR are both connected properly
and the network parameters are set correctly.
c. Please make sure the network and the switch both work.
Q3. The screen has no output after booting the NVR normally.
a. Please make sure the screen, HDMI or VGA cables are good and well connected.
b. Please make sure the screen supports the resolution of 1280*1024, 1920*1080 or
3840*2160 (4K*2K). The NVR cannot self-adapt to the screen of which the resolution is lower
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 use a screen that supports at least 1280*1024,
1920*1080 or 3840*2160 resolution before booting the NVR.

the selected question in the popup window, the password for admin will be reset to 123456 by
default. If you forget the answer of the question, this way will be invalid, please contact your
VITEK reseller for help.
b. The passwords of other users can be reset by admin, please refer to 12.1.2 Edit User for
details.
Q5. The NVR cannot add up to the maximum number of IP cameras?
Take a 16 CH NVR as an example. Some 16 CH NVR support a maximum of 120Mbps
bandwidth input. 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.
