Forgot local menu operation password or network password

  • Please contact your local service engineer or our sales person for help. We can guide you to solve this problem.

There is no video. The screen is in black.

  • IPC IP address is not right.
  • IPC port number is not right.
  • IPC account (user name/password) is not right.
  • IPC is offline.

The displayed video is not full in the monitor.

  • Please cheek current resolution setup. If the current setup is 1920*1080, then you need to set the monitor resolution as 1920*1080 or 1080P capable.

There is no HDMI output.

  • Displayer is not in HDMI mode.
  • HDMI cable connection is not right.

The video is not fluent when I view in multiple-channel mode from the client-end.

  • The network bandwidth is not sufficient. The multiple-channel monitor operation needs at least 100M or higher.
  • Your PC resources are not sufficient. For 16-ch remote monitor operation, the PC shall have the following environment: Quad Core, 2G or higher memory, independent displayer, display card memory 256M or higher.

I can not connect to the IPC

  • Please make sure the IPC has booted up.
  • IPC network connection is right and it is online
  • IPC IP is in the blacklist.
  • The device has connected to the too many IPC. It can not transmit the video.
  • Check the IPC port value and the time zone is the same as the NVR.
  • Make sure current network environment is stable.

After I set the NVR resolution as 1080P, my monitor can not display.

  • Shut down the device and then reboot. When you reboot, please press the Fn button at the same time and then release after 5 seconds. You can restore NVR resolution to the default setup.

My admin account has been changed and I can not log in.

Use telnet and then input the following command:

  1. cd /mnt/mtd/Config/ 
  2. rm -rf group 
  3. rm -rf password 
  4. Reboot the device to restore the default password.

After I login the Web , I can not find the remote interface to add the IPC.

  • Please clear the Web controls and load again.

I use the VGA montior. If I use the multple-window mode, I see the video from the main stream or the sub stream.

  • For 32-channel series product, the 9/16-window is using the sub stream.
  • For 4/8/16 series product, system is using the main stream no matter you are in what display mode.
