Since their mass popularisation in the mid-1980s, baby monitors have become a pinnacle prop in cinema, with films such as The Baby's Room (2006), Nocturnal Animals (2016) and Lullaby (2022) all utilsing the radio system as a horror instigator. In Insidious, the baby monitor tactic is used continuously to elicit big scares over small instances of time, with the strange utterances heard over the transmitter multiple times. In the beginning, each baby check ends in a fake scare, one where the spookiness is almost a hoax. However, during the third case, the camera finally reveals a pale-faced, vampiric-like, suited ghost ominously staring over the child. The baby monitor scene is an exercise in deceit, ceaselessly building up until we no longer expect a reveal of any sort, until that dreaded moment where we are taken by utter surprise.
