All but one of the smoke detectors, the Nest Protect, failed to detect dangerous levels of smoke at the 15 foot mark. How Much do Smart Smoke Detectors Cost?Always weigh the costs against the benefits you might get from a smart smoke alarm. On average, you can expect most smart smoke detectors to cost around $100, though some units cost as much as $250, which can be up to 10 times more expensive than normal units. This can make replacing all of the existing smoke detectors in your home very expensive. To keep costs down, consider using traditional units throughout your home with smart smoke detectors in main areas. Traditional smoke detectors typically cost between $10 and $40.

In 2009, there were an estimated 15,000 CCTV systems in Chicago, many linked to an integrated camera network. New York City's Domain Awareness System has 6,000 video surveillance cameras linked together, there are over 4,000 cameras on the subway system although nearly half of them do not work, and two thirds of large apartment and commercial buildings use video surveillance cameras. In the Washington D. C. area, there are more than 30,000 surveillance cameras in schools, and the Metro has nearly 6,000 cameras in use across the system. The Cheshire figure is regarded as more dependable than a previous study by Michael McCahill and Clive Norris of UrbanEye published in 2002. Based on a small sample in Putney High Street, McCahill and Norris extrapolated the number of surveillance cameras in Greater London to be around 500,000 and the total number of cameras in the UK to be around 4,200,000. According to their estimate the UK has one camera for every 14 people. Although it has been acknowledged for several years that the methodology behind this figure is flawed, it has been widely quoted. Furthermore, the figure of 500,000 for Greater London is often confused with the figure for the police and local government operated cameras in the City of London, which was about 650 in 2011.
