Each camera had its own monitor. One camera, one monitor.
CCTV systems were introduced in the US and the UK during the 60s and 70s.
CCTV systems are over a thousand times more advanced than the basic camera and monitor configurations that first appeared in the 1960s. Systems from the 60s were basic, consisting of very low resolution black and white cameras connected by coaxial cable. Each camera was connected to a black and white monitor. A 16 camera configuration required 16 monitors.
New applications of camera security systems include: underground trains and stations, sports stadiums, retail stores, shopping centers, public facilities, community parks, garages and parking lots.
CCTV Technology Evolution
The basic technology evolved in the 60s. First of all, cctv switch boxes were added. A switchbox would allow the operator to switch between cameras. Operators now could see multiple camera views on one monitor. Only one camera could be viewed at a time.
The 70's brought Multiplexers, VCRs and solid state cameras. Multiplexers allowed the screen to be broken into multiple frames on the same monitor. VCRs allowed easy recording and video distribution. Solid state cameras helped improve reliability and the integration of VCRs.
'First generation' CCTV technology was initially impeded by some fairly major performance related problems.
In the 80s we learned that VCR recorders had many problems. VCR recorders were temperamental. The quality of the recordings was very poor. The combination of low resolution camera images, poor quality video tapes and low tech solutions meant that grainy and unclear images couldn't be relied on even for conclusive identification purposes.
VCR technology couldn't allow the operator to review and record events simultaneously and it was a very time consuming process to find and review specific events.
There was no motion detection capability and no way of viewing events from a remote location.
Expensive for what you get
Even though early CCTV systems provided only relatively basic functionality and moderate performance, they were quite expensive - both in terms of the initial equipment cost and the installation. Since this is still a new growth industry, there is still a lack of qualified and skilled installers.
The Next Generation CCTV
The 'next generation' of CCTV system arrived in the mid 90s. The new technology was a computer based Digital Video Recorder (DVR)
DVRs allow images to be recorded at much higher resolution than previously. DVR eliminated a major problem with first generation CCTV systems - Video Tape! Worn out, forgot to change the tape, VCR recording tape.
DVRs are automatic and never require user intervention. When it is time to look at recorded images, the DVR continues to record. Images are time and date stamped and are very easy to review.
DVRs using IP (Internet Protocol) technology allow authorized remote users to view, transmit two way audio, fully control the cameras and system itself over a local area network (LAN), a wide area network (WAN) or via the internet.
With such flexible access, the modern generation of CCTV cameras may be operated remotely from a control center or, in fact anywhere with internet access. Equally, high quality digital images may be streamed anywhere and captured at a convenient and secure location. But it isn't only the operating platform that has developed significantly; camera technology too allows far more functionality.
Today's generation cameras can PTZ - pan, tilt and zoom, have higher resolution options, a large variety of lenses and are also capable of operating in 'night vision. Audio is also now part of CCTV DVR technology. An operator is now able to synchronize motion based video events with audio analysis. Two way audio transmission allows the operator to question possible intruders, give instructions to staff and to record/search/replay in both audio and visual form. Next generation DDTV DVR systems are compatible with earlier camera technology, and are scaleable, flexible and can be integrated with a broad range of other management systems, such as access control and building management systems.
CCTV has certainly come a long way since the 1960s; it's clear that the future of CCTV is secure and that technology will continue to develop to meet the changing needs of the surveillance market.

Stars of CCTV $7.98 Naturally, NME called Hard-Fi's debut album, Stars of CCTV, "the album of the year" upon its U.K. release in 2005. A year later, the Staines, England, foursome had a Mercury Music Prize nomination under its belt as well as two Brit Awards nods and a U.K. number one album. Those following the buzz on the other side of the Atlantic finally got their wish with the domestic release of Stars of CCTV in mid-March. With the popularity of Franz Ferdinand, Kasabian, and the Kaiser Chiefs simmering down around this time, Hard-Fi stepped into the American pop conscience when they were supposed to. While their spark and spunk are near matches of those aforementioned acts, Hard-Fi delivers more of an angst kind of performance. Frontman Richard Archer is fueled by Tony Blair's England. After all, these are four friends from a southwest London town. They sound like a garage band while delving into the monotony of everyday suburban life, referring to their small town upbringing. Thus a raw kind of work ethic gradually emerges on Stars of CCTV. Their formula of snappy choruses and tight guitar hooks, particularly on "Middle Eastern Holiday" and "Gotta Reason," captures Hard-Fi's youthful presentation. Archer's boyish vocals switch off between gritty and playful. If "Living for the Weekend" does not convince you of Hard-Fi's anxious effort in getting you to ease up on the ho-hum of working for a living, the fresh disco beats of "Hard to Beat" surely will. Hard-Fi's desire to create something solid enjoyable in the midst of everyday monotony is what makes Stars of CCTV an enjoyable first effort. Whether they are singing about having little money, unexpected pregnancy ("Cash Machine"), or a war-torn world ("Feltham's Singing Out"), Hard-Fi looks for something positive. Stars of CCTV offers a reason to look for something positive, too. ~ MacKenzie Wilson, Rovi Performers: Nick Etwell - Trumpet |

Digital CCTV $65.95 The effects of digital technology on the security industry require constant vigilance by security distributors, sales staff, and installation professionals. Today and for the foreseeable future, all security professionals must have at least a basic understanding of digital technology. Digital CCTV addresses this new challenge. Topics convered include compression variables such as Lossless and Lossy, which are explained by reviewing Huffman and Run Length Encoding (RLE), and by relating these forms of compression to ZIP and Stuffit, which are commonly used in personal computers. A review of JPEG, motion JPEG, MPEG and wavelet compression schemes among others, with a comparison of the merits of each, is also provided. As Digital CCTV traces the stream of digital video flow from the computer industry through compression, transmission, display and storage, and explains how analog video signal is converted into a digital signal, the reader will learn and understand the mysteries of digital science. * Explains industry concepts, acronyms and buzzwords acurately and clearly * Covers history, current complexities, and the future effects of digital science *Provides practical information about how digital video works, how digital video is stored and transmitted, what digital systems can and cannot accomplish, and what to expect from digital video equipment in modern CCTV systems |
