You come to the wrong place to ask that. Also, you ask a high level question that has many details to it that need to be flushed out and assessed as to viability. Therefore, nobody can give you a definitive answer - which is why you get the response you are getting.
If you were to ask me 10+ years ago if it was possible sell a camera you have an idea about developing, my first reaction would be you are crazy. Today we see a very success company in GoPro.
There are two sites you can check out that can get you started on the research you can do yourself and the types of questions you need to be thinking about. Since I cannot add urls, I will give you two search phrases:
"Iowa State University Business Idea Assessment"
"INC Assess Idea Market Potential"
Obviously, Google is your friend as each of these can give you terms to search deeper. And, there are forums and other resources that are specific to small businesses (e.g. Small Business Administration) where you can get answers to specifics.
Good Luck!
