9. Q & A

Q : I am now using Router. How do I set the network?

A : [In case of single DVR]

1) If the router supports DMZ function, please use DVR with DMZ.

2) If you want to use Port Forwarding function, please refer to the below port list to be used

in DVR.

[In case of multiple DVRs]

1) Please set not to be duplicated each other by using Port Forwarding function.

Ex) If a DVR is set as “TCB base port : 9010, Mobile port: 9011”, set another DVR as

“TCP base port 9012, Mobile port 9013”

2) If the web port is changed, add “:port number” to the DVR address at address section of

Internet Explorer.

Ex) DVR #1: 80(http://123.123.123.123/) DVR #2: 8088(http://123.123.123.123:8088)

3) Port duplication might cause functional restriction of time sync and event notify.

4) In case of DDNS server port, it works properly regardless of port duplication.

Q : I cannot connect to DVR at RemoteManager.

A : Please try to connect at the Web Viewer(Internet Explorer).

If you cannot see log in window at the Web Viewer(Internet Explorer), please check the

network condition.

Q : There is “Buffering” message displayed, continuously, when I playback(VOD).

A : 1) It is displayed, in the multi-channel playback mode, for synchronizing playback time

between channels.

2) In the case that there is no recorded image at that time(due to no motion detection,

no sensor and so on), the message is displayed to synchronize playback time.

3) Please control the time with Intelligent Search Bar or reconnect at the desired time.

Note

Remote user should be pre-registered in DVR with designated permission level.

If a user has been registered in RemoteManager only (not in DVR), then such user can

not be connected to the DVR via RemoteManager
