Group 1 Introduction to CCTV and Security Systems - CCTV: Closed-circuit Television: Involves using cameras to send signals to a precise place on a restricted number of monitors. Unlike broadcast television, video surveillance signals are not broadcast publicly; instead, they may use a variety of transmission mechanisms, such as point-to-point, point-to-multipoint (P2MP), or mesh wired or wireless lines. Although practically all video cameras meet this criterion, the word is most typically used to describe those used for surveillance in locations that require increased protection and continuous monitoring. This strategy is essential for increasing security in a variety of scenarios. Brief History of Closed-circuit Televisions - An early mechanical CCTV system was developed in June 1927 by Russian physicist Léon Theremin. This system, originally requested by CTO (Soviet Council of Labor and Defense), comprised a manually operatedscanning-transmitting camera along with a wireless shortwave transmitter and receiver, achieving a resolution of one hundred lines. The system was commandeered by Kliment Voroshilov and was notably demonstrated to prominent figures such as Joseph Stalin, Semyon Budyonny, and Sergo Ordzhonikidze. It was later installed in the courtyard of the Moscow Kremlin to monitor approaching visitors. - Another significant early CCTV system was installed by Siemens AG at Test Stand VII in Peenemünde, Nazi Germany, in 1942, primarily for observing the launch of V-2 rockets. - In the United States, the first commercial closed-circuit television system became available in 1949, designed by CBS Laboratories and offered by Remington Rand under the name "Vericon". This system was marketed as not requiring a government permit because it utilized cabled connections between the camera and monitor, rather than relying on over-the-air transmission. Evolution of CCTV CCTV in the 1940s  The 1940s marked a significant turning point in the development of CCTV technology.
