Bathroom and Bedroom Fall Radars Need Opposite Logic, So They Ship as Separate Versions

A fall detection radar must answer whether a person has ended up on the floor when they should not, and the answer differs by room. In a bathroom, only standing and sitting are normal, so any low posture is treated as an event, and the room's single door helps the radar know when it is empty. In a bedroom, lying down is normal for most of the night, so the bed and similar furniture are excluded from the monitored zone while the rest of the room is watched fully. Because these two rooms require opposite conclusions from the same measurement, the product is sold in two versions, and using the wrong one leads to false alarms or missed falls. The rooms are priority targets because cameras and staff cannot cover them, and elderly people are most likely to fall alone there.
