Each camera has its own monitor. A camera, a monitor.

closed circuit television was introduced in the U.S. and the United Kingdom 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. The 60 systems were basic, consisting of very low resolution black and white cameras connected by coaxial cable. Each chamber was connected to a black and white monitor. A camera setup requires 16 to 16 monitors.
Emerging applications of security camera systems include: underground stations and stations, sports stadiums, shops, malls, public facilities, community parks, garages and parking lots.

CCTV Technology Evolution
The basic technology was developed in the 60s. First, switch boxes closed circuit television have been added. A distribution box allowing the operator to switch between cameras. Operators now could see multiple points of view of the camera on a monitor. Only a camera can be seen in a time.
The 70s brought multiplexers, VCRs and solid-state cameras. Multiplexer allows the screen is divided into multiple frames on the same monitor. Video players allows easy recording and video distribution. solid-state cameras have helped to improve the reliability and integration of VCRs.

"First generation" CCTV technology was initially prevented by some very important results related problems.

In the 80 we learn that many problems had VCR recorders. video recorders were temperamental. The recording quality was very poor. The combination of images low resolution of the camera, poor video tapes of poor quality and technology solutions means that the granular and clear images could not be invoked even for purposes of positive identification.

VCR technology could not allow the operator to review and record events simultaneously and was a time-consuming process to find and review specific events.

There was no motion detection capability and no way to see events from a remote location.

Expensive for what you get
Even though the first CCTV systems provided only relatively basic functionality and operation moderate, they were quite expensive - both in terms of initial equipment cost and installation. Since this is still a growth industry, there is still a lack of facilities qualified and trained.

CCTV The Next Generation
The "new generation" of the closed loop system Television arrived in the mid 90s. The new technology was a computer based on Digital Video Recorder (DVR)
DVR allows for recording images with a resolution much greater than before. DVR eliminated a major problem with first generation CCTV systems - Video Tape! Worn out, he forgot to change the tape, VCR tape recording.

DVR are automatic and require no user intervention. When it's time to look at the images recorded, the DVR continues recording. Images are timed and dated and are very easy to review.
DVR with IP (Internet Protocol) technology allows remote authorized users to view, transmit two-way audio, fully control the cameras and the system itself in a local area network (LAN), wide area network (WAN) or via Internet.
With such flexible access the modern generation of CCTV cameras can be operated remotely from a control center, or indeed anywhere with Internet access. Similarly, images high quality digital can be heard anywhere and captured in a suitable and safe place. It's not just the operating platform that has evolved significantly; camera technology also allows much more functionality.

Today's generation can PTZ cameras - pan, tilt and zoom, have more options resolution, a wide variety of lenses and are also capable of operating in "night vision. The audio is also now part of CCTV DVR technology. The operator is now able to synchronize the movement of events based on video with audio analysis. Two-way audio transmission allows the operator to question possible intruders, give instructions to staff and to record / search / playback of audio and visual form. DDTV Next generation DVRs are compatible with the technology anterior chamber, and are scalable, flexible and can integrate with a wide range of other management systems such as access control and building management systems.

CCTV has come a long way since the 1960s, it is clear that the future of CCTV is secure and that technology will continue to evolve to meet changing needs of the market surveillance.
