Inception

CCTV was introduced in the early 1960’s when company’s such as the Radio Corporation of America (RCA) began introducing vacuum tube television cameras. The cameras grew rapidly throughout the 1970’s due to the increased reliability and technical improvements in the tube type cameras. The industry advanced the most in the 1980’s with the introduction of the solid state cameras. By early 1990’s all tube cameras of the past 30 years were replaced by the solid state cameras. The most significant explosion of the CCTV industry was the worldwide increase in theft and terrorism and commensurate need for protecting assets.
