Troubleshooting
1. Device Fails to Start or Restart Continuously 2. Failure to Use Remote Controller
3. Blurred NVR preview screen
4. Internet disconnected to NVR.
5. Blurred playback screen/ Fail to search
6. Cannot play downloaded
recording file backup videos.
7. I had set all the mobile detector alarm, occlusion alarm and video occlusion right. But
why does it still not work?
It might because the ONVIF of your IPC does not support such functions.
8. No IPC searched
It might because your NVR or IPC is disconnected to internet. Please try to check if your device
is correctly connected to internet, or check if there is an IP conflict.
9. No sound when preview or playback
1) Check if there is an audio in your IPC: you can test it through IE or the built-in client or
through computer.
2) Wrong audio format: NVR only supports G711 audio compressed format. Please adjust
your format through IE of the built-in client.
10. No diagram after being saved.
It can be a wrong username or password. It might also because the camera gun may use a
proprietary protocol leading to incompatibility.
Suggestion: use camera guns that support i8 or other proprietary protocol or the internationally
agreed by ONVIF.
Possible Reasons:
1)
NVR’s upgrading wrong program leads to
the damage of system software.
2) NVR encounters power or board faults,
please contact the supplier for repair.
3) HDD error, please replace the HDD.
4) Panel program wrong choice:
Setup→Device Parameter→Setup
Information→Interface Version.
Aluminum panel please choose MINI.
Other plastic panels choose corresponingly
01, 02, 05, etc.
5) NVR IP address conflict.
Possible Reasons:
1) Please check whether the batteries in
Remote Controller are installed correctly,
especially the postive and negative.
2) Please check whether the batteries in
Remote Controller are still charged.
3) Please check whether the Remote
Controller window is hidden.
4) Please check the Remote Control
address in NVR is matched with Remote
Controller address.
Possible reason:
Unmatched video input feature. If the
camera uses NTSC, but the NVR uses
PAL, this could lead to a blurred screen.
Possible reasons:
1) Please check if your physical network is
normal or not.
2) Please check your NVR parameter setting.
3) Please check if there is IP conflict.
Possible reasons:
1) Program misread. Please reboot the NVR.
2) Bad track or bad cluster in the hard disk
data. Please detect your hard disk and
change a new one if damaged.
3) NVR hardware fault. Please contact your
supplier.
Possible reasons:
1) Player installing mistake.
2) Wrong USB flash disk or wrong mobile hard
disk drives file system.
3) No DX9.0 or higher diagram speedup.
