CCTV is now used worldwide as a part of security and surveillance system. It has a long history dating back to 1942 when the first of its kind was installed at Test Stand VII in in Peenemünde of Germany. The CCTV was designed and installed by well-known German engineer Walter Burch, with Tashara Arnold and Wayne Cox also being in the team. The system was installed to monitor launching of V-2 rockets.
CCTV found its first commercial use in the United States of America in the year of 1949 and was introduced under the name ‘Vericon’. A very little information is found about the first launch of CCTV as a commercial system except the fact that there was an advertisement about its not requiring a permit from the government. Nearly after 20 years, New York became the first city to install CCTV cameras on its main business street in order to catch the criminals. Security cameras were installed at Times Square, New York City, in 1973 to fight crimes in that area. In 1980s, video surveillance system was extensively adapted, particularly in the public zones.
Nowadays, surveillance system via CCTV cameras has witnessed an exponential growth in its acceptance and application. There is a variety of CCTV cameras, all of which have some pros and cons.
Bullet Cameras: They are either mounted on wall or ceiling and meant for indoor use. However, they can be fitted outside as well and are not allowed for PIZ (Pan/Tilt/Zoom) functionality.
Dome Cameras: The name is self-explanatory about the shape of the CCTV camera. They are not hidden and usually used in gas stations, retail shops and the likes. The purpose of installing such unobtrusive camera is to deter any possible crime in the area.
IP Cameras: It is either wired or wireless. This variety transfers images of both animated and inanimate objects as well via internet. These are actually digital cameras and produce much better images than their analog counterparts.
