Hello. I actually used three things to monitor my mother when she was still ambulatory. I used a baby (audio) monitor to listen in on her activity, a motion detector (which used a beam and activated a remote device that sounded as soon as the beam was crossed), and a video/audio monitor (finally found one that would work across a long distance). I'll try to copy and paste into this message links to the devices I used.
I used a Graco digital monitor with two parent units (so that I could leave one in the bedroom and carry one with me as I moved about the house):

I used this motion detector, with a remote alarm, though they sell all different kinds:

And I used (and still use) a video monitor made by the Summer company. I LOVE this - I can keep track of my mother's every move, if I wish. They don't seem to make my model any longer, but these are similar:

I finally had to stop using the plain audio monitor, because I would lie awake listening in on my mother and wondering what she was doing. If I had it to do again, I'd get the motion detector with the remote alarm and the video/audio monitor and not get the baby monitor. But everyone is different. I know your struggles. Good luck.
