Fall detection cameras: buy a new one, or add software to the one you own?

The two routes

Everything in this category does roughly the same job. Watch a scene, decide whether what just happened looks like a fall. What separates them is what you have to buy and install first.

One route sells you a device with the detection inside it. The other connects to a camera already in the house and reads footage it was already recording. That is the whole difference, and it sets your cost, your installation and how soon you can start.

Dedicated devices

Kami Fall Detect is the one most people find first. A standalone camera at an introductory $99.99, with fall detection and emergency response on a subscription reported at $45 a month¹. Kami claims 99.5% detection accuracy, which is the company’s own figure rather than an independent test, and worth reading that way.

The subscription includes round-the-clock professional monitoring. If a fall is detected and caregivers do not respond, Kami says the service escalates to emergency services through RapidSOS¹. Hold onto that. It comes back below and it matters more than the price.

Above the consumer tier things get specialised. Nobi builds a ceiling lamp that runs vision AI on the device itself, processes images locally, and only sends one anywhere if it thinks somebody has fallen³. It also lights the room when a person sits up in bed at night, which is prevention rather than detection and is arguably the more useful half.

Vayyar Care uses radio waves instead of a lens. No camera, no image of anyone, which means it works in the dark and through shower steam. That is why it can go in a bathroom when nothing else here can². Sentinare renders movement as a stick figure. HomeGuardian and IntelliSee are built for care facilities more than families.

If the bathroom is your real worry, the radar option is the one to look at. It costs more and it is a less mature consumer category, but it is the only thing on this page that reaches into that room.

Software on a camera you already own

If a camera is already pointed at the room, the alternative is to change what reads it. Ring opened an App Store in March 2026⁴ and apps in it, Remy included, connect to a Ring account and review clips the camera has already recorded.

Remy is $49 a month per camera after a 7-day trial. Faces are blurred before anything is analysed. Instead of every movement, you get possible fall-risk events, hazards and unusual inactivity. No new hardware, no installation visit. That is the entire argument for this route.

The catch is that you inherit the camera you have. Its field of view, its range at night and where it points were all decided for some other purpose, and no software changes where a lens is aimed.

What neither route does

The shared ceiling matters more than the difference between the two, and most comparison articles go quiet here.

Neither covers a bathroom, radar aside. Neither can promise to catch everything, because anything out of frame or behind the sofa or beyond the camera’s range at night is simply not in the recording. Neither is a medical device.

On dispatch they split, and this is the distinction to get right. Remy notifies you. There is no monitoring centre behind it. Kami’s subscription tier does include professional monitoring and says it escalates to emergency services when caregivers do not answer. So “does anybody except me respond to this” is a question to ask of each product individually. Do not assume the answer carries across the category.

If nobody is reliably awake and available to act on an alert, that one difference decides your whole purchase.
