Intouch is an ActiveX container. You need an ActiveX control that displays the video, Intouch doesn't have much to do with the problem.
Most camera systems come with software that includes an ActiveX control. You have to install the ActiveX control and then tell Intouch to make it available to your application. There's a button in the Window Maker wizard to add an installed ActiveX control to Intouch.
Some cameras have video available through a web browser, either ActiveX or Java. Windows has ActiveX browser control.
