Questions Reasons
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 cannot connect to the IPC
●
Make sure that the IPC has booted up.
●
IPC network connection is right and it is online
●
IPC IP is in the blocklist.
●
The device has connected to the too many IPC. It
cannot 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 cannot display.
Shut down the device and then reboot. When you reboot,
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 cannot log in.
Use telnet and then input the following command:
cd /mnt/mtd/Config/
rm -rf group
rm -rf password
Reboot the device to restore the default password.
After I login the Web, I
cannot find the remote
interface to add the IPC.
Clear the Web controls and load again.
There is IP and gateway, I
can access the internet via
the router. But I cannot
access the internet after I
reboot the NVR. Use command PING to check you can connect to the
gateway or not. Use telnet to access and then use
command "ifconfig–a" to check device IP address. If you
see the subnet mask and the gateway has changed after
the reboot. Upgrade the applications and set again.
I use the VGA monitor. I
want to know if I use the
multiple-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.
Daily Maintenance
●
Use the brush to clean the board, socket connector and the chassis regularly.

The device shall be soundly earthed in case there is audio/video disturbance. Keep the
