Hi, I am looking for surveillance equipment that is suitable for my grandmother who is living alone and can use it. My grandmother was a very nostalgic and introverted person, and she didn't want to move in with us and just stay in her own little house. But her knees are bad, and from time to time we worry about her accidentally falling over. We live in CA, more than 40 kilometers away from her, and with the current epidemic, it's even more difficult to visit her.
We had plans to hire a home care worker, but my grandmother wasn't willing to accept strangers staying home for long periods of time. Some foreign friends have suggested to me to install some tech monitoring devices that can keep track of the user's movements, but do not produce any images or videos and therefore protect the user's privacy. But those device manufacturers are so far away, I searched nearby merchants and didn't find anything similar. Do you have any suggestions?
