I think those systems that are designed for the elderly should also have
some mechanism to detect movement and alarm if there is no movement
for a specified time between particular nominated times, so that if the
individual does die or is unconscious, the system will alarm then too.

Obviously the time between detected movements is different at
night and day and in the bedroom and the rest of the house etc.
