A case note from the New Zealand Privacy Commissioner’s Office:
A couple complained to us that one of their neighbours’ security cameras could film into their lounge windows and parts of their garden and pool area.
[…]
The couple said the camera was an intrusion into their privacy because it could record their activity “every minute of the day and night”. At night time, it appeared the camera was operated by a motion sensor because a red light would flash on and off when either of the couple moved or adjusted their blinds.
[…]
The neighbours explained that the camera in question was a cheap plastic dummy camera, used as an “intruder deterrent”, as they lived in a remote, exposed location, and the property had been burgled previously while they had been away overseas.
