Although there are still some airports around the world which use close circuit television cameras in their airport security systems, many would consider these technologies to be rather old-fashioned. They do have their place in airport security and has proven to be quite helpful in many instances. However, they have certain limitations which many unscrupulous individuals can take advantage of.
For instance, it is a fact that most standard close circuit television cameras require lights in order for them to be able to capture any image at all. That said, when darkness comes, many of these close circuit television cameras are rendered useless unless there is a light source nearby which illuminates the area that is covered by the close circuit television camera. Without these light sources, close circuit television cameras won’t be of much help to the airport security personnel.
