Where can I find in-home security for Alzheimer's wandering?

There are many, many options from light beams across doors to computerized monitoring, to cameras. I'd do an internet search and look at all the options, then think about what exactly, from the whole lot, you are comfortable with. From there, contact several companies and ask for specific information of the ones you want to investigate. That will help narrow down the options.
Also, your local in-home health care agencies may have tried and true suggestions that their clients use. Nothing like word of mouth.

There is a Alzheimer's Portable Door Lock, that can stop them at the door. This Lock should stop them from wandering at night.
