motion detection with monitor

My 90 yr old mother has lived with us for 4 yrs (since my dad died)....we have tried two different motion cameras, but unfortunately, the wifi connections keep getting lost....my husband wants to get a monitor without wifi, but i'm having difficulty finding one! Samsung used to make one that vibrated (so as not to wake my husband), but no longer. I'd like to view what's going on with her, but i guess i may be stuck with just a motion sensor....would like one that is NOT LOUD though. A foot pad is not advisable as she could fall. Does anyone have any suggestions? thanks

yes, we did buy the uniden.....it serves our purposes....unfortunately, the alarm part, the volume does not go down low enough (i'd prefer a vibrate so that it wouldn't wake my husband )...this one sounds like an elephant trumpeting...it is quick and short, though, but when said parent can get up betw 3-5x a night, it can get a bit annoying. I honestly was hoping samsung still sold their baby monitor that was also motion detection...it was perfect with a vibrating noise (my daughter in law had it and i was there when it worked)
i'm sorry if this was not a good enough answer for you. this whole process is so frustrating....i don't see how there cant be a company out there that makes what we need@

I need suggestions please. My grandfather has dementia and Alzheimer's. Having a bad day. Refuses to take meds what can I do?
