1980 adoption of CCTV systems expands to companies primarily in the US and Europe due to theft and fraud.

1986 Scientists at Kodak developed the first Megapixel image sensor capable of capturing 1.4 million pixels.

1992 are developed the first mini cameras and the industry is inspired to produce increasingly smaller cameras.

DEVELOPMENTS INFLUENTIAL

 

1993 A bomb attack in Bishops gate in London by the IRA leads to system construction "Ring of Steel" (steel ring) consisting of hundreds around the English capital CCTV cameras.

In 1993 Liverpool in England, was unveiled the kidnapping followed by boy James Bulger murder only two years by identifying the images captured by the shopping center CCTV system where he was kidnapped.

2006 The city of Chicago Announces Virtual Shield operation (Virtual Shield), making it the city with the largest US video monitoring system.

CAMERAS VOLUME

 

2006 The City of London is one of the most watched in the world, with about 4.2 million cameras in the streets, and across the UK there is about one camera for every 14 inhabitants. Even in England, it is estimated that each person appears in CCTV cameras at least 300 times a day.

2007 It is estimated that over 97% of all telecommunications world's information travels over the Internet. Services such as browsing e-mail and messages are part of our day-to-day.

2010 maturity of the technologies and IP camera manufacturers, H.264 and development of VMS solutions for network video management, make the technology the best choice system large-scale, industrial, urban and enterprise video surveillance solutions.

CCTV IN NUMBERS

 

2011 According to estimates by In-Stat Forecasts company sold about 41 million cameras and other surveys from historical manufacturing and sale of CCTV equipment data indicate that there are approximately 210 million cameras operating in the world.

2013 According to estimates by ABESE, São Paulo is the city that has more security cameras in Brazil, about 1.5 million devices, representing a camera for every 7 people.

2014 The Internet is one of the main media, high-definition video devices in HD and 4K, high speed wireless networks, smart phones, high-capacity computer tablets are massively present in businesses, homes e as IP networks are the basis of communication for most applications even in the industry.
