This clip is widely recognized as the camera monitor sound from Five Nights at Freddy's 2, the 2014 survival horror game by Scott Cawthon. The game's security-camera mechanic made the effect memorable, and players began using it in montages, reaction edits and horror memes across video platforms. It still shows up because a single short sound can instantly signal FNAF, surveillance and incoming danger. It is often paired with a fnaf jumpscare scream when creators want a full monitor-check-then-scare sequence.
