Not medical advice. This guide is general information to help families compare services. Talk with your parent’s doctor about their fall risk, medicines, and what kind of support they need. A medical alert system doesn’t replace 911. If someone is hurt or in danger, call 911.
The worry usually starts small. Mom doesn’t pick up the phone one evening, and you spend twenty minutes imagining the worst before she calls back from the garden. Or Dad mentions, almost in passing, that he “had a little tumble” last week and got himself up eventually.
If you’ve had that feeling, you’re far from alone. Many families start looking at medical alert systems at exactly this point: a parent who wants to stay in their own home, and grown children who want to know help will come if something goes wrong.
This guide compares two of the best-known services, Medical Guardian and Bay Alarm Medical, using what each company publishes, and explains the questions worth asking before you sign up. We haven’t used either service ourselves. Just as important, we’ll be honest about what these devices can’t do, especially automatic fall detection.
The short version
- Falls are common. The CDC says more than one in four adults 65 and older falls each year, and fewer than half tell their doctor. Falling once doubles the chance of falling again.
- Both companies offer 24/7 U.S.-based monitoring, in-home and on-the-go devices, optional automatic fall detection, and monthly, quarterly, or annual billing, according to their sites.
- Medical Guardian says it has no long-term contracts and no equipment, activation, or cancellation fees, and gives prorated refunds for unused service.
- Bay Alarm Medical says you can cancel anytime with unused months refunded (minus shipping), offers a 15-day trial, and states its services are HSA/FSA-eligible.
- Fall detection is a backup, not a guarantee. Medical Guardian’s own fine print says it doesn’t detect 100% of falls, and research on wearable fall detectors in real homes has found many missed falls and false alarms.
- Traditional Medicare doesn’t cover medical alert systems, according to both companies. Some Medicare Advantage plans may. Check with the plan.
- Prices: both sites show multiple packages and change offers often. Check the current price, and look at the total for a year including any device fees.
Why falls matter so much
The CDC’s numbers are sobering (CDC):
- More than one in four older adults falls each year, but less than half tell their doctor.
- One out of ten falls leads to an injury that limits activity for a day or more or needs medical care.
- Falls are the most common cause of traumatic brain injuries in older adults.
- Many people who fall, even without injury, become afraid of falling and cut back on activity, which makes them weaker and more likely to fall again.
Part of the danger is being unable to get up or call for help. That’s the gap a medical alert system is designed to fill.
What a medical alert system is
The National Institute on Aging describes it simply: you wear a button on a necklace or bracelet, and if you fall or need help, you press it to get emergency help. NIA notes there’s a fee and that it’s usually not covered by insurance (NIA).
Most systems come in two broad types:
- In-home systems. A base unit plugs in at home (connected by landline or cellular), plus a wearable button. Press it, and the base unit’s speaker lets you talk to a monitoring center.
- Mobile systems. A small cellular device with GPS that works at home and away, useful for a parent who still drives, walks, shops, or visits friends.
Many plans add automatic fall detection, which tries to sense a fall and call for help even if the button isn’t pressed.
NIA also points out cheaper alternatives some families use: a charged cell phone carried around the house, a smart speaker that can call contacts, or a smartwatch that can call for help or detect hard falls (NIA). These can work well for some people. The main differences with a monitored service are a staffed center that answers 24/7 and a simple one-button design that many older adults find easier than a phone.
Medical Guardian: what the company says
From Medical Guardian’s FAQ (Medical Guardian):
- Devices: in-home systems (including one that needs a landline and others that use cellular), and mobile devices with GPS. One mobile device also uses Wi-Fi to help pinpoint location.
- Monitoring: a 24/7 monitoring center located in the U.S. The company says operators can reach people who speak languages other than English or Spanish through a translation service.
- Care Circle: up to four emergency contacts, each with up to three phone numbers.
- Fall detection: available as an add-on pendant with several in-home systems and built into one mobile device. Their fine print states that fall detection does not detect 100% of falls, the user should press the button if able, and the fall pendant must be worn around the neck to work properly.
- Contracts and fees: no long-term contracts and no equipment, activation or cancellation fees (marked with a footnote on their site, so read the terms), with prorated refunds for unused months.
- Billing: monthly, quarterly or annual.
- Testing: the company recommends testing the device at least once a month.
- Extras: a lockbox for a house key so responders don’t have to force the door, wall-mounted buttons (including voice-activated), and a protection plan for lost or damaged devices.
- Medicare: standard Medicare doesn’t cover it; some Medicare Advantage plans or Medicaid may.

Bay Alarm Medical: what the company says
From Bay Alarm Medical’s pricing and FAQ page (Bay Alarm Medical):
- Devices: an in-home system (landline or cellular), an all-in-one mobile device, a compact mobile button, and a smartwatch.
- Monitoring: 24/7 U.S.-based monitoring centers, which the company says are in Utah and Idaho.
- Fall detection: optional on in-home and mobile plans. On some in-home packages it involves a separate fall detection wearable with its own device fee, and on mobile plans the company notes fall detection applies to the mobile device only.
- Caregiver app: GPS location and low-battery notifications for mobile devices.
- Trial: 15 days from delivery. If it’s not right, send it back for a refund minus shipping.
- Cancellation: cancel anytime by phone, with unused months refunded minus shipping and any free-month promotions. In-home base units are leased and must be returned.
- HSA/FSA: the company states its services are eligible for HSA/FSA reimbursement.
- Extras: a “Vial of Life” kit for keeping medical information at home for emergency responders.
- Medicare: traditional Medicare doesn’t cover it; some Medicare Advantage, private, and long-term care insurance plans may.

On paper, the two are close. The best choice depends less on brand and more on your parent’s daily life, which we’ll get to below.
The honest truth about fall detection
Fall detection sounds like the perfect answer for someone who might fall and be unable to press a button. It can help. But families should know its limits before relying on it.
- Medical Guardian says plainly that fall detection doesn’t detect 100% of falls and that users should press the button if they can (Medical Guardian).
- Real-world research is sobering. In a small 2015 pilot study of 18 older adults living in the community, a wearable fall detector worn over several months caught only one real fall, missed others, and set off 83 false alarms. The manufacturer’s lab testing had suggested much higher accuracy (PMC). That was one device in one small study, and technology has improved since then. A 2021 review of systematic reviews in BMC Public Health was more positive, concluding that wearable sensors can be effective for detecting falls and calling for help. Even so, its authors called for more testing in real-world settings with frail older adults and for fewer false alarms (PMC).
What this means in practice:
- Fall detection is a safety net with holes. Teach your parent to press the button whenever they can.
- Expect some false alarms. Sitting down hard or dropping the pendant can trigger a call. That’s usually fine, since the operator checks in, but some people find it upsetting and stop wearing the device. Talk about it ahead of time.
- It only works if it’s worn. The best device in the drawer does nothing. Comfort, looks, and a water-resistant design for the shower all matter, because the bathroom, with its wet, hard surfaces, is one of the rooms NIA singles out for fall-proofing.
Choosing for your parent: questions that matter more than brand
Where do they spend their days? If they’re mostly home, an in-home system may be enough. If they still drive, walk the dog, or go to church and the store, consider a mobile device with GPS.
Do they have a landline? Many homes don’t anymore. Cellular systems avoid that problem but need decent cell coverage at the house. Ask the company to check coverage.
Will they actually wear it? Ask your parent which they’d prefer: a pendant or a wristband. Let them choose. People wear what they’re comfortable with.
Can they hear the speaker and be heard? If hearing is an issue, check the volume during the trial period. Bay Alarm offers a 15-day trial, and it’s worth testing the system in different rooms, including the bathroom.
Who are the emergency contacts? Decide as a family who gets called, in what order, and who has a key. A lockbox can save the front door in an emergency.
What does it really cost for a year? Add the monthly fee, any device fee, any fall detection add-on, and extras like a lockbox or protection plan. Compare the yearly total, not just the monthly headline.
What are the cancellation terms? Both companies advertise no long-term contracts. Still, read the terms for returning equipment and how refunds work.
Don’t stop at the button
A medical alert system helps after a fall. Preventing falls matters even more. The CDC and NIA suggest steps that make a real difference (NIA):
- Strength and balance exercise, such as tai chi or a program from a physical therapist.
- A medication review with their doctor or pharmacist. Some medicines cause dizziness or drowsiness.
- Eye and hearing checks.
- Home changes: grab bars inside and outside the tub or shower and near the toilet, nonslip mats, good lighting with switches at the top and bottom of stairs, and no loose throw rugs (NIA).
- Standing up slowly, since blood pressure can drop on standing.
- Telling the doctor about any fall, even one without injury.
The CDC’s STEADI program has free brochures for older adults and families on fall prevention, linked from its falls facts page (CDC).
The bottom line
Medical Guardian and Bay Alarm Medical both offer 24/7 U.S.-based monitoring, in-home and mobile devices, optional fall detection, and no long-term contracts, according to their own sites. Compare the yearly total cost and trial or refund terms, check cell coverage at your parent’s home, and above all pick a device your parent will actually wear. Treat fall detection as a helpful extra, not a guarantee, and pair any alert system with real steps to prevent falls in the first place.
