When you open the PTZ Camera Menu with Chrome and you see the error "Not installed OCX", please follow the instructions below.
Open Chrome and navigate the browser to the IE Tab extension page.
Locate and click the "Add to Chrome" button at the top-right of the screen.
Click "Continue" when the download dialog box opens at the bottom of the screen.
Click "Install" when the dialog box opens after the download is finished. An IE Tab icon will appear next to the address bar and inform you when it is finished installing.
Click the IE Tab icon (Top Right of your Chrome Window) to open a new tab with an Internet Explorer address bar. The tab interfaces with Internet Explorer, allowing Chrome to use ActiveX extensions.
Navigate to a website (PTZ Cameria IP Address) with ActiveX protocols. Click the acceptance dialog box which appears underneath the address bar. The ActiveX protocol will automatically install and reload the page when finished.
This extension requires Internet Explorer to be installed on the same system, so it will not work in Mac OS X.
If ActiveX controls remain unusable with the IE Tab extension, look for a Netscape Plugin Application Programming Interface (NPAPI) version of the ActiveX protocol. Since ActiveX protocols are an Internet Explorer-exclusive feature, browsers like Google Chrome, Apple Safari and Mozilla Firefox use NPAPI protocols instead. Although ActiveX and NPAPI are similar, some websites may not support both formats.
