Surveillance Day is observed on August 16, encouraging individuals to acknowledge the prevalence of surveillance cameras, particularly in urban areas. Participants are invited to spend the day looking for these cameras and playfully waving at them, reminiscent of children waving at trains. The day serves as a light-hearted reminder of the ongoing debate surrounding privacy and surveillance, with many feeling uneasy about being constantly monitored. Despite concerns, surveillance cameras have contributed to increased safety in cities by aiding in crime detection and apprehension. The observance also aims to foster a sense of community and humor in the face of serious issues related to surveillance and privacy. The day was previously known as Wave At The Surveillance Cameras Day before its name change in 2018.
