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 camera 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 needs of the surveillance market.

Advantages Of Acquiring A Network IP Camera For Your Safety And Comfort
When thinking about of home security, we {think about surveillance cameras, sound detection products and other electronic security instruments as well as tools.~Surveillance cameras, sound detection systems and other electronic security instruments and gizmos are what we think about when contemplating home security.~We consider surveillance cameras, sound detection devices and other electronic security appliances and tools, when we think about home security.} However nothing is more functional than the surveillance cameras, since they're utilized in banks, stores, schools, and also houses. When we look at security none is more dependable than seeing what is truly happening in your doorsteps. With today’s era, the surveillance network cams have developed since their simple origins in the mid 1990’s.
During the 1990’s the very first IP network cam was used, utilizing the software Linux to operate the cameras. During the late 90’s the first decentralized IP camera was introduced. The network surveillance cams that were run by Linux have video, alarm and recording management functions which enable the cam to work without necessitating licensed video management software to regulate the recording, event and video administration. Following after that, was the development of Megapixel network IP camera devices, which were available at 1,2,3,5 and 11 megapixel resolutions.
Currently, there are two various kinds of security cams on the market, first is the IP Camera, and the second is the Closed Circuit Television Technology. As opposed to the CCTV cam that uses video signals to send out to a specific point, the IP camera uses internet signals and network LAN devices. For many who use CCTV and broadcast television formats, it has been mentioned that the usage of the analog system is already out-of-date and the usage of an IP network camera is the present and future of protection.
There are tons of benefits of using surveillance network cams, one, which most likely is the most important, is that the possessor, managers or security heads should be able to monitor their boutiques, areas or facilities even when they are not in the premises. This is because they can view the area through the world wide web and their computer or 3G Phone. This is a remarkable advantage especially for the owners since they will be able to attend meetings even outside of the country and still see the happenings in their respective organizations.
For the people wanting to use the network surveillance cameras, the benefits and the assurance of having your boutique secured is high. First, the cost benefits, as a result of decreased system cost because of the networking infrastructure of the IP network. Secondly, decreased space necessities can be enjoyed as steering is made only through the computer and doesn't need wires or switchers. Third, the IP camera may cover even more areas than an analog cam and thus supply more security for your investments. Lastly it has higher resolutions and as a result better visibility. Therefore, deciding on a network IP camera for your business is the best way to safeguard your facilities.
