Smile - you're on camera!
The first television camera was invented in 1942 by Walter Broch. But security cameras weren't used in homes until the 1960s. The first home security camera was designed by the American Marie Van Brittan Brown. Today, this technology is used around the world. In London today, more than 500,000 security cameras are installed. The average Londoner is recorded about 300 times a day!
