I am interested to hear about the experience of other care givers who use home security to monitor dementia suffers living alone. I am considering a camera outside the front door to see coming and going. Also in the kitchen as this is where most risk is. Someone suggested to also have voice connection so I can speak to my father via the cameras. At first I thought this would scare him, however as he is already having hallucinations and has several 'friends' I am starting to think it may work. I appreciate each sufferer is different, but any incite into experiences with using these technologies would be much appreciated.
