There are so many different monitoring devices and services out there and the new technology is overwhelming me. I'm hoping to find some good direction on the best ones - tried and true. Hopefully, someone has experience with these - what worked, what didn't, and recommendations. Also, maybe which combinations of them might work best. I'm looking for Indoor surveillance cameras? Medical alert system? Door motion sensor? Medication dispenser? Any other recommendations that help to keep a loved one safer at home by themselves?
