Video surveillance is not new; it has been around for quite a while. One of the first recorded application for closed circuit television system (CCTV) was back in 1942. It was used to view the launch of V2 rockets in Germany. In the US, commercial surveillance applications began around 1947. In 1957 a number of companies such as General Precision Labs (GPL division), provided CCTV camera systems for education, medical and industrial applications.
Early CCTV equipment and TV broadcast equipment shared technology. Both camera systems supported grey-scale video (not color) and measured and defined performance using NTSC standards.
Color cameras became available in the 1950s, and there was a debate on whether or not color was better for surveillance. Black-white (or grey-scale) cameras provided better resolution and low light sensitivity, while color made it easier to identify someone by the clothes they were wearing.
Now seeing in the dark is another matter we have to go back to the Second World War Historically, many armies would not fight at night because the confusion, lack of quality on-time intelligence, and increased communication difficulty made night fighting a very dangerous and very risky proposition. Only the most highly trained soldiers with a well rehearsed plan could take to the battlefield at night with any clear chance of success.
