If video in the simplest words, the video surveillance began with a simple monitoring of CCTV . As early as 1965, there were articles in the press in the United States suggest that police use of surveillance cameras in public spaces. In the year 1969, the police cameras were in the city of New York, in the vicinity of the building of the City Council & 39; City Hall. The practice is & 39 n d rapidly & 39; other cities, with the CCTV systems (CCTV) monitoring by the staff at all beginnings times.
Analog diversion
When VCR video surveillance on the market , video surveillance really beaten rhythm. Using the technique on analog video tape recordings of the band meant to be maintained surveillance on the tape as evidence. The seventies were an explosion in the world & 39; use of video surveillance in all & 39, and the application of the law to control the movement and the divorce proceedings.
England Systems Video Surveillance in the four major railway stations and subway in 1975 began to monitor the traffic on the major arteries on the highway also & 39; time. In the United States, & 39; use of video surveillance & 39; n is not so widespread as in the years 1980 to the public spaces, but owners of shops and banks, has quickly the value of it.
Businesses, Were in the flights, including banks, d & 39; mini-marts and gas stations, began to develop systems to monitor video and & 39; a deterrent effect in l & ; amp; 39; hope & 39; capture the thieves, particularly in industry areas.
The crimes of & 39; insurance has also noted the video surveillance duty - the worker& 39;s compensation fraud, Counterfeiting accident of complaints and a variety of d & 39; other cases began its favor industry & 39; if they could gangs, the disabled workers who allegedly & 39; limbus to a family reunion.
For private citizens, the analog technology used, especially in the 1970 1980 for the start of the worst side of human nature - Cheats spouses and parents. The private investigators were able, more graphics and irrefutable evidence d & 39; business and the stupidity of parents in the film with plans, and videotapes are often in the family court.
The evidence, in many cases the disadvantage is that after a certain time, the owners and employees are a convenience, and not to change the records daily or cassettes not & 39; use after months d & 39; reused. There was also the problem of & 39; registration at night or low-light conditions. While the concept was good, the technology & 39; has not yet reached its peak. L & 39; next step was the camera Charged Coupled Device (CCD), the use of IT-chip technology. The new cameras expanded practical applications in the video surveillance, a weak light in the night and registration possible.
In the years 1990, another & 39; progress in the history of video surveillance is making huge progress in Convenience -- Digital Multiplexing. If the units affordable digital has become, he has revolutionised the monitoring of the industry allow & 39; l & 39; recording of several cameras at once (more & 39, a dozen times in the The most cases). Multiplex and digital functions added as time and movement, which & 39; declaration, which has allowed the & 39; except much waste videotape.
By mid-1990, the ticket machines in the United States United States and in most regions of the world are video cameras installed to the registration of all transactions. After the first attack on the World Trade Center in February 1993, the police in New York, the FBI and the CIA all of the installation of surveillance cameras throughout the region. Soon, in many countries are also either with the help of the CCTV recorded on tape or video surveillance to major sporting events, could be the potential hot spots, including the World Cup soccer games in the Giants Stadium video surveillance 1994.
Digital make faster, clearer, more efficient video surveillance
Digital realized complete sense that the price of digital recording & 39; went with the IT revolution. Instead of changing the tapes all day & 39; user registration reliable monitoring a month on the disk, because of the compression and low capacity cost.
The digitally stored images were so clear that the often stored images Grainy analogous to the recognition was immediately improved by the police, private investigators and & 39; other people, the video surveillance to identify & 39;. With digital technology, you can also edit images necessary for the improvement of transparency even further by the light, & 39; improve the & 39; image zoom on frames, etc.
The second wave d &; 39; growth of video surveillance is the emergence of digital & 39; in the United States. From 1997, the police through the country increasingly & 39; installation of video surveillance cameras in public buildings, the projects of residential and & 39; areas like New York & 39 S Washington Square Park, the NYPD has also begun, the mobile surveillance vans at political meetings and other large gatherings (including festivals and parades), & 39, under the auspices of the & 39; Technical Assistance Response Unit (TARU).
In use at home increases with the beginning of nanny cams
As more women& 39;s career began in full-time in the 90 years, the maker of digital video surveillance was a market segment that & 39; n had not used -- Monitored what happens at home when the parents left. The nurse came was a great success and is a way for parents d & 39; out that the government and the housewives are really anything to do at home, with the popularity of these cameras is growing kids.
The l & 39; industry to develop ever smaller cameras with higher resolution, which could be hidden almost anywhere. The result was a stroke of luck for the development of the industry & 39; with new versions of cameras, digital video surveillance from almost all month.
9/11 redefined the video surveillance for the future & 39; changed the
Nothing concept or knowledge of the population of video surveillance, so that the tragic events of 11 September 2001 when the World Trade Center was attacked by terrorists. Where the people on the video surveillance as a problem, the risk of never touching, it was now a question of & 39; immediate and sustainable importance.
Software developers began refining the programmes to strengthen the video -- monitoring, including programs for face recognition could be the difference in key points of the face around with the familiar faces registered mug plans or photos of terrorists and other criminals. While the old versions are not always reliable, which later became gradually been refined and used by the & 39; application of the law in some areas. In May 2002, the Office for parks in the United States against the recognition of installed software on the computer & 39; video cameras, video surveillance in the Statue of Liberty and Ellis Island.
That same year, & 39; International Sydney Airport in Australia installed Smart Gate, an automated border crossing for all airlines, the members of the crew & 39;. Photo use of biometrics, video surveillance scans is a member of the crew & 39; his face and compares it with the photo of the passport and confirmed the game in less than ten seconds, the speed of the processes markedly border.
In December 2003, Royal Palm Middle School in Phoenix, Arizona installed recognition of the face, such as video surveillance d & 39, a pilot program for the monitoring of children and sexual offenders. They told the community, but it is used by many for this as a way to the kidnapper and child of the Internet revolution molesters.
The & 39; in the video surveillance
The Internet enabled for video surveillance is used practically everywhere , and d & 39; be, anywhere in the world. With twists satellite signals in the world, you can now look & 39; nn & 39; important, no matter where on the laptop. L & 39; eye in the sky is a reality with streaming video.
Sadly Digital, the lowest common denominator in streaming video is the peek-a-boo amateur porn industry, websites, which are heavily increasingly on the Internet, but these real-time video-streaming technology, which many real operations.
Streaming of video surveillance is as a system, so that you can monitor your site from & 39;-over in the world with access to the Internet & 39; because the video images will be stored on a Web server. The quality is excellent, with high compression ratio (1800:1, in some cases) for the storage and the movement of the functions, such as activation and & 39, 39 & l, e-mail notification when & 39; activity, if you like. L & 39; Internet has truly revolutionized the video surveillance by the abolition of all borders in the world.
What l & 39; future of video surveillance?
The newest trendy, fun must-have gadget for consumers these days is the image & 39; phone, which of the photos and video streaming for the family and friends of & 39 only one click. What the TV ads fun not say & c 39, is that these phones can also easily be used to the video surveillance. Almost everyone has a mobile phone in the hands of these days, someone is a & 39; stand on the corner d & 39, a road is so banal, that virtually & 39; n, are important to you, your shooting knowledge.
Rather embarrassing that the installation of cameras, the future of the strengths & 39; order to use these phones can be integrated features such as video surveillance, public telephones in a The package 24 / 7 watch-dog public. The officials of the police and officials of the Federal published, the remaining phones with video & 39, so that they immediately photos of suspects, the residue in a database to a program to detect faces. If new Amber Alerts are issued, the video clips can all officers of the Public Prosecutor and efficiently.
It & 39;& 39;s quickly obvious that the digital technology and video streaming, we have moved into l & amp , 39, the age of & 39; be in a position to complete visual monitoring and storage of the evidence. We reach the world, or through the streets with the personal monitoring, but we are still advances, such as the new video phones clearly illustrates. L & 39; future is not afraid to see more big giant, which ultimately became a part of the history of & 39; video surveillance.
