Wave at Surveillance Cameras Day
August 16 · Level 3 · #1643 of 2238
A playful day that invites you to smile and wave at the cameras watching streets, shops and lobbies. Somewhere, a person behind a screen might finally get something fun to look at.
How it is celebrated: people wave, pull funny faces or give a cheerful greeting to cameras in lifts, car parks and shops, then share the stories with friends.
The first closed-circuit television system was built in Germany in 1942 by engineer Walter Bruch, to watch V-2 rocket launches from a safe distance.
