Tag Archives: CCTV Security Systems

CCTV security systems were introduced in the US and the UK during the 60s and 70s.

CCTVsecurity systems are over a thousand fold more advanced than the basic camera and monitor configurations that first appeared in the 1960s. Systems from the 60s were basic, comprised 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, mercantile establishment , mall , public facilities, community parks, garages and car park.

CCTV Technology Evolution The basic technology developed in the 60s. Foremost, 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 watched at once. The 70′s brought Multiplexers, VCRs and solid state cameras. Multiplexers allowed the screen to be broken into numerous frames on the same monitor. VCRs allowed straight forward recording and video dispersion. Solid state cameras helped improve reliability and the integration of VCRs.’First generation’ CCTV security technology was impeded by some fairly major performance related problems .

In the 80s we determined that VCR recorders had many troubles. VCR recorders were erratic. The quality of the recordings was poor. The combination of low resolution camera images , poor caliber video tapes and low tech solutions meant that grainy and unclear pictures couldn’t be relied on even for conclusive identification purposes.

VCR technology couldn’t permit the operator to review and record occurrences at the same time and it was a very time consuming procedure to find and go over specific happenings.There was no motion detection capableness and no way of looking at events from a removed location.

Costly for what you get Even though early CCTV  systems provided only relatively basic functionality and moderate performance , they were very costly – both in terms of the initial equipment cost and the installation . Since this is still a fresh growth industry, there is still a lack of qualified and proficient installers.

The Next Generation CCTV security systems arrived in the mid 90s. The fresh technology was a computer founded Digital Video Recorder (DVR) DVRs allow images to be recorded at much higher resolution than previously . DVR did away with 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 necessitate user intervention. When it is time to look at taped images, the DVR continues to tape. Images are clock time and date stamped and are very easy to review. DVRs using IP (Internet Protocol) technology allow authorized distant users to see, transmit two way audio, fully command the cameras and system itself over a local area network (LAN), a wide area network (WAN) or on the internet . With such flexible access, the New generation of CCTV cameras may be operated remotely from a control center or, in point of fact anyplace with internet access.

Equally, high quality digital images may be streamed anywhere and captured at a convenient and secure location. But it is n’t only the operating platform that has evolved significantly ; camera technology too permits 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 too now part of CCTV DVR technology. An operator is now able to synchronize movement based video events with audio analysis. Two way audio transmitting 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 early camera technology, and are scaleable, flexible and can be incorporated with a wide range of other management systems, such as access control and building management systems.

CCTV has surely 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 necessities of the surveillance market.

CCTV security systems were introduced within the US and the UK during the 60s and 70s.

CCTVsecurity systems are in excess of a thousand fold superior to the basic camera and monitor configurations that first appeared in the 1960s. Systems from the 60s were basic, composed of very low resolution black and white cameras connected by coaxial cable. Each camera was plugged into a black and white monitor. A 16 camera configuration needed 16 monitors. New applications of camera security systems include : underground trains and stations, sports stadiums, sales outlet, shopping mall, public facilities, community parks, garages and parking lot .

CCTV Technology Development The basic technology evolved in the 60s. First , 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 cameras. Multiplexers allowed the screen to be broken into multiple frames on the same monitor. VCRs allowed straight forward recording and video distribution . Solid state cameras assisted improve reliability and the integration of VCRs.’First generation’ CCTV security technology was initially impeded by some fairly major functioning related troubles.

In the 80s we ascertained that VCR recorders had many troubles. VCR recorders were temperamental . The quality of the recordings was very poor . The combination of low resolution camera images , poor caliber video tapes and low tech solutions meant that grainy and unclear pictures couldn’t be relied on even for conclusive identification purposes.

VCR technology couldn’t allow the operator to review and record occurrences simultaneously and it was a very time consuming process to find and review specific events .There was no motion detection capableness and no way of viewing events from a remote location.

Expensive for what you get Even though early CCTV  systems supplied only relatively introductory functionality and moderate functioning, they were quite expensive – both in terms of the initial equipment cost and the installing. Since this is still a fresh growth industry, there is still a lack of qualified and proficient installers.

The Next Generation CCTV security systems arrived in the mid 90s. The fresh technology was a computer founded Digital Video Recorder (DVR) DVRs allow images to be recorded at a great deal higher resolution than in the past. 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 need user intervention. When it is time to look at taped images, the DVR continues to tape. Images are clock time and date stamped and are very easy to review. DVRs using IP (Internet Protocol) technology allow authorized removed users to view , convey two way audio, fully command the cameras and system itself over a local area network (LAN), a wide area network (WAN) or on the internet . With such pliable access, the New generation of CCTV cameras may be operated remotely from a control center or, in point of fact anywhere with internet access.

Equally, high quality digital images may be streamed anywhere and captured at a convenient and secure location. But it is n’t only the operating platform that has developed significantly ; camera technology too permits 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 sight . Audio is also now part of CCTV DVR technology. An operator is now able to synchronize movement based video events with audio analysis. Two way audio transmitting allows the operator to query possible trespassers, give instructions to faculty and to tape search replay in both audio and visual form. Next generation DDTV DVR systems are compatible with former camera technology, and are scaleable, flexible and can be incorporated with a broad range of other management systems, such as access control and building management systems.

CCTV has surely come a long way since the 1960s ; it’s clear that the future of CCTV is secure and that technology helps keep to develop to meet the requirements of the surveillance market.
