Question: My Internet Explorer will not install the ActiveX add-on, what can I do to get this working?

Answer 1: You are using Internet Explorer 64bit. You will need to use the 32 bit version

Answer 2: The Security settings may be preventing the installation. To overcome this you can add a security exception for the DVR. To set this folow the steps below:-
 - Open Internet Explorer
 - Go to your DVR address and login
 - Click the Alt key on your keyboard to open up the Internet Explorer Menu
 - Select the Tools Menu
 - Select Internet Options
 - Select the Security Tab
 - Click Trusted Sites
 - Click Sites button
 - Untick 'Require server verification (https:) for all sites in this zone'
 - Click Add button (your DVR url should be displayed in the add box)
This will add this to the list below
 - Click Close
 - Set the  Security Level for the zone to Low (slider bar)
 - Click OK
 - Refresh the page, it should prompt to install the ActiveX control
 - Confirm to install

If no slide bar is not visible under Trusted sites:-
(this is the case with Windows XP and some versions of Internet Explorer)
 - Click the 'Custom level' button
 - Go down the list to 'ActiveX controls and plug-ins'
 - Change 'Download unsigned ActiveX controls' to 'prompt'
 - Click OK

Answer 3: If you are running Internet Explorer 9, you may need to run through compatibility mode. This is the button to the right of the address bar that looks like a broken page. When it is in blue, it is enabled.
