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.
