I want to focus a simple curtain of my window at all times, and thick curtains on the sides and behind closed doors if you want the camera for movies and others. Is there any kind of hardware you have two bars for this? If so, where can I find them? Or do I have in a bar and another bar, clean in and thicker, it weigh? Tips or advice would be great!
