The caregiver role is new to me so I really appreciate this site. I am looking for the best caregiver pager system... two different types actually. I would like one my parents could use to alert each other (dad needs help so he buzzes mom who is on the other side of the house) AND also a system that would ring straight into 911, if necessary. ADT came out and gave us a sales pitch on that one, but was looking for other recommendations along those lines. Thanks!
