You want to develop a body cam for law enforcement? I don't think current systems or costs are holding them back at the moment. Instead, most law enforcement agencies simply don't want them. Even if they were mandatory, they would likely be disabled, or accidentally broken or obscured during key events.
If you want to see officers wearing body cams one day, you're better off getting involved in politics.
