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 SMTs 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 SMT.
c. Please make sure the HDDs are compatible with the SMT. 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 SMT.
b. Please make sure the network cables of the IP camera and SMT 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 SMT 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 SMT 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 SMT or just have no display. Please change a screen at 1280*1024, 1920*1080 or
3840*2160 resolution before booting the SMT.

dealer for help.
b. The passwords of other users can be reset by admin, please refer to 12.1.2 Edit User for

Q5. The SMT cannot add up to the maximum number of IP cameras?
Take the 8 CH SMT as an example. Some 8CH SMT support a maximum of 80Mbps
bandwidth input (the real product shall prevail). 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.
