controls on top of applications

I want to see the image from the cameras when I use the application, however, it makes no sense to write codes for different camera models. Most camera vendors already give access to applications that provide access to them. I want to have an interface in your program without a background. to open the camera application or other information application, and open the control interface from your program on top of it. I can comfortably use any camera and still use your app to control it. In any case, your application is great and I will try to transfer all projects to it for the subsequent sale of my products
