Case Study 1: Excessive use of CCTV in Nursing Home

In Ireland, there was a complaint against a nursing home which installed CCTV cameras in corridors, day room, kitchen, front entrance, staff room, residents’ dining room, games room and drug therapy room. Concerns were raised that the CCTV system was linked to the owner’s smart phone, allowing the cameras to be checked remotely.
