Monitor that I can view from outside?

My husband is bedridden, and it's just he and I here, so obviously I have to go out and about to get groceries, go to Dr etc. What I use is the Blink Security cameras. I have one on the mantle in living room where my husband is, and I can check on him any time I want from my phone. I have their older models that do have sound, but they now make them with 2 way talk. This system has worked great for me and has given me peace of mind when I have to be away.

I have a YI camera that transmits to any smart phone.  I put my smart phone on my bike and can see.  Will not help with BP etc, it is to prevent mom from wandering off

There are the home security systems that you can install that have cameras you can place in rooms and see what is going on on your phone.
BUT if you're mowing the lawn are you going to be able to watch him at the same time? Even if you are sitting in the yard having a cup of coffee and reading a book if you look up and see him in the living room and the next time you look up he is on the floor in the bedroom if 5 minutes have passed that is a LONG time in an emergency. And I can sit and read a book and loose track of time. Or if it is not reading a book it could be checking email or even doing the laundry in another part of the house.
I gotta tell you this would scare the crap out of me!
Would it be possible that until he actually has a diagnosis and an acceptable treatment could you get a caregiver or even a family member to stay with him if you are gone? (Or hire a neighbor to do your yard) I really dislike being told I have to confine myself to the house so this would be difficult for me and I would have to have someone that I could call on to stay in the house if I had to go out.

Carla, it sounds as though your dear husband needs a higher level of care than one person can give at home. Have you considered placing him somewhere where others are around 24/7 to monitor him?
