HDD Capacity Calculation 306
My admin account has
been changed and I can
not 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 can
not 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 can
not 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 montior. I
want to know if I use the
multple-window mode,
should 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.
