A front camera has nothing to do with safety. It does nothing to reduce the chances of you getting in an accident. It only helps after the fact, to show what happened. You want to be able to establish, after the fact, what went wrong/who is responsible. That is for civil or criminal liability, not safety.
(OK - I'm not entirely correct. A front camera can help with safety indirectly, I suppose, if you review the footage and change your riding behavior based on your review. But, it doesn't sound like you intend to use it in that way.)
A camera can also help with safety if it is visible to others and to the extent that it cause others to moderate their behavior.
