Age old question: Do it all or find a niche

That question continues to pop up in our CameraSecurityNow.com business. We start to specialize in one area and then a new product or a new application for an old product comes out and we start working in that directions. Here is a forum for discussion on the subject, Tech-Army.org Camera Security Systems Blog Forum but I am not sure if it is possible to specialize in one area if you want to keep up with the technology.
