## 7.6 Exclusion and Solutions of Exception

1. Client browser can not playback video, preview or Real-Time Monitoring page has no video pop-up:

Firstly, make sure to use IE8 and above browser, client and Video Server on the same network segment and the video AxtiveX installation is successful. If the ActiveX installation fails, above all, uninstall the video ActiveX that were originally installed, run the "regsvr32-u NetVideoActiveX23.ocx"command, and then in the browser, set all the options in "Tools -> Internet Options -> Security -> Custom Level" on the ActiveX to "Enable or Prompt", re-open the browser, re-login screen and open the video preview page, run the button "all add items of the site".

2. In the E-Map, no video pop-up after you click the small camera icon:

Above all, make sure to use IE8 and above browser, client and Video Server on the same network segment and the video AxtiveX installation is successful. Also, view whether the browser is preventing the temporary window pops up, if so, changed to allow window pops up to the site.

3. Video linkage is triggered, the video server does not have video or size of the video file that the client downloads from the Video Server is 0kb:

First, make sure that the software server has set TimeServer (keep the Windows time service and has set the NTP function of the video server), it is recommended to set the time interval of the video server smaller to ensure accurate synchronization software server and video server time, so as to keep the time consistent between software server and controllers. You'd better set Linkage Recording Time more than 5 seconds, to avoid executing video linkage commands delay, which may lead to the downloaded 0kb video file.
