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. Change a new one.
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 normally.
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 1920*1080. The NVR cannot self
adapt to the screen which does not support the 1920*1080 resolution. The screen will remind
you that the screen resolution is not supported by the NVR if the screen resolution is lower than
1920*1080. Please change a screen at 1920*1080 resolution before booting the NVR.
Q4.
The NVR cannot add up to 16/32 IP cameras?
The 16 CH NVRs support a maximum of 120Mbps bandwidth input; 32 CH NVRs support a
maximum of 160Mbps bandwidth input. Refer to the following picture. 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 16 or 32 cameras.
