6. Q & A
1. NVR 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) Check that the settings are correct at the menus: [Event > Sensor],
[Event > Motion Alarm], and [Record > Schedule].
2. There is a HDD installed but “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 that the display screen is stopped at 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 to allow
connection to the NVR by domain (domain.dynlink.net) without memorizing IP.
5. Remote software connection to the NVR 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) Check whether port 80 is opened or not.
6. Image is not shown after login at WEB monitoring
TCP Base port should be opened. Default of TCP base port is 9010.
