Are there monitors available that allow the caregiver some measure of freedom of movement?

@Scared170, it sounds like Blink cameras recommended by funkygrandma59 are very similar to Ring cameras which we use and love, and can recommend 100%.

Ring cameras can either be plugged into electric sockets, or wired into the house by an electrician, and also have two way microphone. They also have a very easy way to temporarily stop recording anything (for privacy). Your friend will need a smart phone (to view the action after setting up the service). Download the Ring app to the smart phone, plug the Ring device in, then hover the phone camera over the piece of paper from the Ring box, which will automatically activate the new Ring camera.

If your friend likes the Ring camera she can add more devices to the house as time goes on. We bought one Ring camera and aimed it at front door (luckily we have an outdoor electric plug near front door) due to a flurry of thievery in our neighborhood. We were so thrilled with having a pair of eyes outside our door (we could see when mail and packages had been delivered as well as the camera showed our parked car and we felt good that we could protect against the raft of catalytic convertors’ thefts, and so much more.) We bought more cameras and feel great about it, for example we live in coyote territory, they easily jump fences, and they’re sometimes prowling in our backyard. We have a camera inside, aimed out our back glass, and I now always check motion on the backyard camera before I physically go out back. Our cameras caught hail falling last week, it’s a once in a few year happening. As you can tell, we love our cameras and now feel more secure.

I am confident home cameras will help your friend (at least in the short term) care for her husband whilst not being forced to be in the room with him 24/7.

What a good neighbor you are to try to help the couple!

Thank you! Will check out Blink cameras. We two neighbors would like find things to help make our friend's life more tolerable as this moves forward. Right now, the diagnosis is new, the DMV notified and his license pulled, and she is just just beginning to think about how to find her way.

Any of your security cameras would work as she could check on him on her phone while she's out and about, and most have 2 way talk, so she can not only hear what's going on but can talk to him as well.
I used the Blink cameras when my husband was completely bedridden in our living room, and I had to run to the store or even just wanted to sit outside for a little while. It was nice for me to be able to check in on him any time I needed to. It worked great for overnight as well, as I didn't have to get out of bed to go check on him, I could just pull up the camera on my phone in the living room and check on him. They are fairly inexpensive, and work well. There are many others available as well. You can just have her "Google" security cameras, and let her take it from there.
