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.
Q4. Forget the passwords?
a. The password for admin can be reset through “Edit Security Question” function.
Click “Edit Security Question” in the login window and then enter the corresponding answer of
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.

Q6. The IP camera which connects to the PoE port of the NVR cannot be displayed
automatically in the camera list, why?
a. Please check whether the resource of the PoE port is occupied by another IP camera that is
added through network.
l Take the 16 CH NVR with 8 PoE ports as an example. The resource distribution of the 16
CH IP cameras is shown in the picture below.
When you add IP cameras through network, the IP cameras will occupy the resource from CH1,
CH2, CH3, CH4… by the adding sequence; if you directly connect the IP cameras to the PoE
ports of the NVR, the IP cameras will occupy the resource from CH9 to CH16 according to the
number of the PoE port each IP camera is connecting to.
Supposing that 12 CH IP cameras have been added to the NVR through network and no IP
camera has been directly connected to the PoE port. The 12 CH IP cameras occupy the 8 network
resources from CH1 to CH8 and 4 PoE resources from CH9 to CH12 which are supposed to be
occupied by connecting the IP cameras directly. In this situation, if you directly connect one IP
camera to PoE5, PoE6, PoE7 or PoE8, the IP camera will be displayed in the camera list
automatically; if you connect it to PoE1, PoE2, PoE3 or PoE4, it won’t be displayed in the camera
list by showing resource conflict; if you just need to connect it to PoE1, PoE2, PoE3 or PoE4,
you should first delete the IP camera which occupies the PoE port resource and then reconnect it
to the PoE port.
l Take the 8 CH NVR with 8 PoE ports as another example. The resource distribution of the
8 CH IP cameras is shown in the picture below and the adding rules of the IP cameras are similar
to the rules mentioned in the above. Please refer to the above for details.
