It is estimated that there is a camera for every 14 people. Moreover, it is very possible that if you are in London you are recorded about 300 times within 24 hours.
Also, you may not know that the largest video surveillance system in a precinct is located in the Singapore International Airport, where not less than 3,000 cameras are connected in the same system.
