9. No sound when preview or playback
1) Check if there is an audio in your IPC: you can test it through IE or the built-in client or
through computer.
2) Wrong audio format: NVR only supports G711 audio compressed format. Please adjust
your format through IE of the built-in client.
10. No diagram after being saved.
It can be a wrong username or password. It might also because the camera gun may use a
proprietary protocol leading to incompatibility. Suggestion: use camera guns that support i8 or
other proprietary protocol or the internationally agreed ONVIF.
11. There is a videotape prompt of a certain diagram and also have images when double
clicked, but no image in multi-channel preview, why?
Right click that channel and there will be a pattern pull-down list in the Remote Configuration,
try to replace the main stream with a sub stream and save it. If there is still no image, it might
because the sub stream is set too high, less than 1m is suggested.
12. A multi-channel preview is working correctly, but when double-click on the single
picture, it turns to black screen or the image stuck, unable to playback the video.
Please check whether your IPC is 1080p, if yes, then click on the Settings - > device
parameters - >pattern, and see if you can use 1080 pattern. 1080p videos can only display
sub stream under the 720P channel pattern. Please set 1080p IPC to the specified channel.
Select the correct mode and reboot OK.
13. Can not login to the IE viewing?
Please set up according to the following method:
1)
IE setting--Internet options--Security--Custom level--enable all relevant options of
ActiveX.
2) Find and delete original plugin file "dvr_activex" at first ,then download and install it
again.
