CURIOSITY:

The video surveillance was born in part analog, and its history is much shorter than that of the anti-intrusion systems, present in the history of man since ancient times in different forms and applications. The first experiment of CCTV is attributed to the German engineer Walter Bruch in 1942. The plant was built by Siemens AG in Peenemunde on the ramp of the launch Prüfstand VII, and was used to monitor the launch of rockets V-2, the most sophisticated military missiles of the Second world war. With regard to the video recording, the prototype of a recorder on magnetic tape was developed in 1952 by Ampex developed prototype video recorder to tape using a rotating nozzle and a belt that was moving relatively slowly. At the beginning of 1956, Ampex demonstrated the VR-1000, the first in the series of recording on a video tape 2-inch Quadruplex (4 tracks). The first television broadcast magnetically-recorded and broadcast on a delayed basis using the new recording system Ampex was "Douglas Edwards and the News", a program of the CBS, the November 30, 1956.
