how i can active camera in my adobe conecct in my imac

I don't have Adobe Connect so I'm just going back to basic principles for things to check.

• -> System Preferences-> Security & Privacy -> Camera
• If Adobe Connect is in the right hand box is it checked?
• If it is there but not checked open the padlock with your password and check it.

As I said I'm not familiar with Adobe Connect so all I can advise is to look in the A.C. preferences to see if there is way to enable a camera. If you can't see this anywhere then try looking on the Adobe Help Centre.
