i used it for Mum when she was at home to prevent opening her bedroom door during the night to check on her and disturbing her. It worked well. It meant that I could lift my head off the pillow and see that she was alright and go back to sleep again. She knew it was there and would call me if she wanted me.
But when I talk to professionals they say it is abusing dignity and privacy.
I would actually feel more reassured that she wasn't being mis-treated now that she is in a nursing home, knowing that there was a senior person monitoring her care occasionally.
What is the difference between multiple members of staff giving private and personal care and a senior member of staff overseeing.
I would rather think of Mum as being safe and well cared for.
I would be controversial and go further to say that due care is not being given without ensuring safety with all vulnerable residents and all staff being observed to ensure good practise. With safety measures in place to prevent abuse of dignity and privacy.
