This recent incident made my think of it.
I have simple business idea to share. This can be a marketing idea for existing company and a new business model for new entrepreneurs.
I am little skeptic about the the placements of CC Camera in Banks, Store and Offices. Why are those camera are placed on the top corner only? It only records the head and hardly can recognized the face. Let it be visible and people should know that they are recorded. If budget is an issue then they can use one in top corner and one near door or reception where it can clearly see one face. This can be a good marketing and convincing tool for the clients.
