Bed Alarm Alternatives to a Pressure Pad (2026): Radar, Beam Sensors, Under-Mattress

Pressure pads wear out, slide, and false-alarm when someone rolls. Families looking past them usually want a sensor that does not sit on the mattress. The honest list is radar, infrared beams, and under-mattress presence pads. None of this is a ranking.

Disclosure: I am Dovy, founder of Komori Care. We are building a contactless bedside sleep monitor, coming 2027, wellness only. It is not a bed alarm.

Quick answer

• Radar: Vivago SentioAI uses 60 GHz mmWave, covers an indoor area of 6 by 6 m, and says it works without cameras or wearable devices. The page lists a bed-exit alarm and a vendor claim of 99% fall detection accuracy. Peninsula Smart Care in Melbourne sells room radar with no camera, no wearable, and no pressure mat, wired into an existing nurse call.
• Infrared beam: Safe-Life sells a dual PIR bed-exit sensor at A$404 as listed in October 2026. It triggers when a leg swings out, and the page says it needs no pads, mats, cords, or consumables.
• Under the mattress: SlumberTek is $99 as listed on ASC in October 2026, for presence and exit, no video or audio. OZI lists bed-exit alerts and says they are not a safety alarm.

One r/dementia poster asked for a sensor that texts when their loved one gets in and out of bed. They said she will not wear a tracker and will not charge one. That is the job these products try to cover. Komori Care (2027) is wellness only and is not a bed alarm.

If you want a wellness night log rather than an alarm, see sleep trackers for seniors who will not wear anything.

Why people look past pressure pads

Peninsula Smart Care, which still supplies mats, says sensor mats wear out, slide, false-alarm when residents shift their weight, and get unplugged during cleaning. Safe-Life markets the PIR beam as a replacement for bed mats and pressure pads. Those are vendor pages, not a survey of every home.

The Reddit thread I could open is the original post only. Comments were blocked. Do not treat one request as a protocol.

Radar, beams, and under-mattress pads

Radar watches the room. Vivago and Peninsula both say there is no camera. Vivago is sold for home, assisted living, and healthcare. Peninsula is built for nurse-call systems in Melbourne facilities.

Beams watch the bedside. Safe-Life mounts PIR curtains 35 to 40 cm from the floor and fires when a leg breaks the beam. The page says that layout is for aged-care facilities, though it can pair with a transmitter and pager at home.

Under-mattress pads watch weight. SlumberTek logs when someone leaves and how long they stay out. OZI sits under the sheet and can notify you if someone leaves and does not return in the window you set.

Ask the care team which category they already know how to respond to. A phone ping is not the same as a nurse-call tone.

Komori Care (coming 2027)

Komori Care is a wellness sleep monitor, 60GHz radar above or beside the bed, no camera required, coming 2027. It is not a bed alarm and not a safety or medical alert system. If you need alerts, use one of the care products above.

FAQ

Do I need a camera to watch for night wandering? Not necessarily. Radar, beams, and under-mattress pads all claim no video. Dementia UK still lists CCTV as an option with consent and privacy limits. Ask the person if they can consent.

Why do people look past pressure pads? Peninsula and Safe-Life describe wear, false alarms, and hygiene. One Reddit poster wanted a text for in and out of bed because a wearable would not stay on.

Are these medical devices? Each vendor decides. Vivago and Peninsula talk about falls and nurse call. OZI says it is not a safety alarm. Check the product page and ask the care team.

Which is best for a home? No ranking. Radar covers a room. Safe-Life says beams suit facilities. Under-mattress pads are simpler to buy online. Match the alert to someone who can wake up and help.

Can Komori Care alert me when someone gets up? Komori Care is a wellness sleep monitor and not a safety or medical alert system. See bed-exit reminder vs medical alert.
