Q & A
1. DVR doesn’t 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 [Device > Sensor] and
[Device > Motion].
2. There is a HDD installed but “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 format.
3. There is nothing displayed on the VGA monitor though electric power is supplied to
DVR.
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 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) In case that the display screen is stopped at logo screen (H.264 Digital Video
Surveillance System), please contact your dealer or distributor.
4. How to make PPPoE connection (xDSL, cable and so on) ?
1) There is no function to log-in at the DVR.
2) Please use the router which supports PPPoE log-in.
5. Is it necessary to open the port when using DDNS (cctv-link.net, dyndns.org) ?
Yes, it is.
DDNS is the function to let remote software acknowledge the changed address of the DVR
(dynamic IP provided by ISP) or to allow connection to the DVR by sub domain (sub
domain.cctv-link.net) without memorizing IP.
6. Remote software connection to the DVR works fine but WEB connection doesn’t work.
1) Some ISP blocks 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. Image is not shown after login at WEB monitoring
TCP Base port should be opened. Default of TCP base port is 9010.
8. No image is shown on MMS connection
Mobile port has to be opened for MMS connection (Default port no is 9011).
9. Image on remote software is 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.
> Turn off the power of Modem & Router.
> After some time (1~5minutes), turn on the power of Modem first and then Router.
> After reconnection, if it is disconnected again after a shot time (in a similar period
later), it means that the ISP restricts upload traffic.
