6. Frequenty Asked Questions
1. Why doesn’t the DVR record images in sensor mode and/or motion mode?
1) It records images only when there is an event for the corresponding mode.
2) Please check if the setting is correctly done at the menu of [Event > Sensor],
[Event > Motion Alarm], and [Record > Schedule].
2. There is a HDD installed but the “No HDD” icon( ) is still shown on the screen.
1) Please check the cable connection of the HDD again.
2) If you can see the HDD list at [System > HDD] but the capacity indicates “0”, it means that the HDD
requires formatting.
3. Why is there nothing displayed on the HDMI / VGA monitor, even though the power is
connected?
1) Please check if the power is supplied properly. When the power is supplied, you can hear the noise
from FAN and HDD operation.
2) Please check the HDMI / VGA cable connection with the DVR. Remove all the cable connections,
except for the monitor cable, and then apply power to the DVR again and check booting status.
3) Please check if the option [VGA] is selected at the rear panel of DVR.
4) In case that the display screen is stopped at logo screen, please contact your dealer or distributor.
4. How do I establish a PoE connection (xDSL, cable and so on)?
1) There is no function to log-in at the DVR.
2) Please use a router which supports PoE log-in.
5. Is it necessary to open the port when using DDNS (dynlink.net or dyndns.org)?
Yes, it is.
DDNS is the function that lets remote software acknowledge the changed address of the DVR (dynamic
IP provided by ISP) or to allow connection to the DVR by domain (domain.dynlink.net) without
memorizing IP.
6. Remote software connection to the DVR works fine but WEB connection doesn’t work.
1) Some ISPs block port number 80. Please try again after changing WEB port.
(8080 is recommended.)
2) Please check whether the port number 80 is opened or not.
7. Why isn’t the image showing after login at WEB monitoring?
TCP Base port should be opened. Default of TCP base port is 9010.
8. The image on remote software suddenly disappeared after displaying for a short time.
1) Some ISP restricts upload data/traffic volume. Please contact your ISP.
2) Upload traffic restriction can be easily checked with the following steps.
① Turn off the power of Modem & Router.
② After some time (1~5minutes), turn on the power of Modem first and then Router.
③ After reconnection, if it is disconnected again after a short time (in a similar period later), it
means that the ISP restricts upload traffic.
