As an avid amateur photographer... this sounds horrible. It sounds very much like what you are trying to do is make people pay to use your cameras mounted on the bus, and not allow them to use the plethora of camera equipment we normally carry on our persons in this day and age. Anything to make another dollar? How about not raping your consumers and instead focusing on making your service better than other ones. Stop making the world a worse place. Take that bit of advice to the owners. There is literally no good reason why you should want to do this. I can even think of several ways to frustrate camera users... but why would I want to make the world a crappier place by helping you to do this?
