Q & A
1.
NVR does not record images in sensor mode and/or motion mode.
1)
It records images only when there is an event for the corresponding mode.
2)
Check that the settings are correct in the menus: [Event > Sensor],
[Event > Motion Alarm], and [Record > Schedule].
2.
There is an HDD installed but the “No HDD” icon (
) is still shown on the
screen.
1)
Check the cable connection of the HDD again.
2)
If you can see the HDD list at [System > HDD] but the capacity indicates “0”, the HDD requires
format.
3.
There is nothing displayed on the HDMI / VGA monitor though electric power is
supplied to the NVR.
1)
Check if the power is supplied properly. You should be able to hear the noise from the fan and
HDD operation.
2)
Check the HDMI / VGA cable connection with the NVR. Remove all the cable connections,
except for the monitor cable, and then apply power to the NVR again.
3)
In case the display screen is stopped at the logo screen, please contact Digital Watchdog’s
technical support for additional information.
4.
Is it necessary to open the port when using DDNS?
Yes, it is.
DDNS is the function that lets remote connections acknowledge the changed address of
the NVR (dynamic IP provided by ISP) or allow connection to the NVR by the domain
(domain.dynlink.net) without memorizing IP.
5.
The remote software connection to the NVR works fine but the WEB connection
doesn’t work.
1) Some ISP blocks port number 80. Please try again after changing the WEB port.
(8080 is recommended.)
2) Check whether port 80 is opened or not.
6.
Image is not shown after login at WEB monitoring
TCP Base port should be opened. The default of the TCP base port is 9010.
