Closed-circuit television (CCTV) is the use of video cameras for surveillance in areas that need close monitoring such as homes, banks, airports, casinos, convenience stores, highways, and public transit. A CCTV Chicago camera system will transmit and record video of real time activity in any specially targeted area.
German engineer Walter Bruch designed the first closed-circuit television to monitor the launch of rockets. The Siemens Company installed the first television monitor in 1942. At that time, it was not possible to record, or store, the video information, so the monitors had to be constantly watched. Due to costs and unreliability, video was rarely used until the early 1970’s when it became more common.
Video surveillance by closed-circuit television started to become more popular as a crime deterrent in the 1980’s. It offered homeowners, private businesses, security companies, government entities, and the police the ability to monitor areas that were vulnerable to criminal activity at reduced costs and without having to provide additional security personnel. A CCTV Chicago system also offers traffic monitoring to cities where it is especially helpful in quickly locating traffic accidents and monitoring complex highway networks in order to detect growing congestion or blockages. Closed-circuit monitoring has become very valuable for public transportation safety where operation personnel can directly observe people in cautionary areas who may be injured by closing doors or moving machinery, subways, trains, or buses.
Currently, software is available to help retailers monitor store environments that will track the actions of workers performing financial transactions, shoppers who would commit retail theft, and injuries or accidents that occur on the business property. Besides the more common uses for closed-circuit television, there is also a personal use for people with visual impairments. Since a CCTV uses a video camera to project an image that is magnified onto a television screen, it can also help assist visually impaired individuals in their daily needs such as reading, writing, or hand work.
