Condition 2: Cannot install Active X controls after logging in.
ActiveX Control components are essential for the NVR server to present user interface. The
message below will show if these controls were not installed. Please try refreshing the browser
first, making IE pop up the prompts again.
Cause 1 : Your Internet Explorer browser version does not support NVR 3 system.
Solution : Make sure your browser is 32-bit version.
Cause 2 : Your browser restricts the installation of add-on components.
Solution : Internet Explorer security settings may restrict the installation of add-on components.
To ensure the NVR server is always accessible from your web client regardless of any change
in browser’s overall Internet security settings, you may add the NVR server site to Internet
Explorer’s trusted sites. Trusted sites are the sites which you consider safe and wish to visit
with low security restrictions while maintaining higher security for the rest of the Internet.
1. On IE browser, click Tools  Safety and make sure ActiveX Filtering is unchecked.
2. On IE browser, go to Tools Internet OptionsSecurity tab, select “ Trusted sites ”,
set the security level to “ Medium High ”, and then click “ Sites ”.
3. Add http://localhost or the NVR server IP to the zone, and clear the box “ Require
server verification (https:) for all sites in this zone ”.
4. Back on Security tab, click “ Apply ” to apply the changes. This will allow ActiveX and
scripting to be available for the chosen sites but not for the Internet as a whole.
