Kerrmedical.com also has a variety of alarms. I use a motion detector type alarm and it sure saves me worrisome nights.
@A myALZteam Member posted about a Smart caregiver motion sensor and pager available on Amazon for under $25. I purchased one and love it. If my husband walks past the sensor the pager which is with me on the other side of the house rings and alerts me he is up and out of bed.
There are bed or mat or door alarms....Amazon is a good site.
Might try a baby monitor you can get one with a camera connected to your cell
Does anyone know if there is a motion sensor device that sends an alert to your cell phone instead of having to carry around a pager?
