Questions Reasons
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.
