Aging in your own home requires finding a balance between independence and safety. Monitoring tools like a personal emergency response system (PERS) can help you achieve this  by connecting you to 24/7 emergency services and caregivers. 

The team at AgingInPlace.org tested a range of PERS devices, also known as medical alert systems, so we can help you or your loved one find the right system. In this article, we compare specific at-home and mobile models based on firsthand testing and research. 

Although we’ve also reviewed the best medical alert systems by brand, this article highlights some of the top models. See our top picks and why an emergency monitoring system can help your plan to age in place.

What is a Personal Emergency Response System? 

A personal emergency response system (PERS) is a device that connects to a 24/7 monitoring center. When you connect to the monitoring center by pushing a button, verbally activating the system, or triggering fall detection, the monitoring center agent will respond, assess the situation, and send emergency services to your location. 

PERS devices are also known as medical alert systems or personal emergency alert devices.

Stay connected to the monitoring center in your home or on the go with Medical Guardian’s Mini Guardian. This mobile system weighs 1.3 ounces (lighter than two AA batteries) and is barely the length of a chapstick tube. The Mini Guardian’s travel-friendly size, two-way speaker, waterproof material, and five-day battery life earned the title “Best for an Active Lifestyle” from our team. 

We like that we could choose from three colors when ordering our Mini Guardian: silver, white, and black. For $10 per month, we also added fall detection to the device. Fall detection is built into the Mini Guardian and doesn’t require separate equipment, unlike some models. The package we ordered included the Mini Guardian, belt clip, detachable magnetic lanyard, and charging cradle.

Note: If you have a pacemaker, this lanyard is not for you. According to the American Heart Association, magnets should not be used in close proximity if you have a pacemaker. “Magnetic fields in magnets in devices and machinery can inhibit pulse generators for ICDs and pacemakers.” Magnets should be kept at least 6 inches away from where your pacemaker is implanted.

When the battery needs to be charged, you’ll receive a verbal cue, with the speaker announcing, “battery low,” along with a red, blinking light for a visual cue. The Mini Guardian snaps into place on its magnetic charging cradle, making it easy to take the device on and off the cradle. When charging, the device again gives both verbal and visual confirmation, with the speaker announcing, “charging,” coupled with a red, blinking light. The Mini Guardian takes three hours to fully charge. 

The Mini Guardian is lightweight and rests comfortably around the neck. Although the user guide states that fall detection can’t be accurately tested at home, we wanted to see if the Mini Guardian would register a test fall. When we dropped it from shoulder length, the device’s speaker said, “fall detected,” beeped 10 times, then connected to the monitoring center. We also performed a test fall from a sitting position, but the Mini Guardian didn’t register this “fall.” We contacted the monitoring center from three different locations, and the monitoring center agent verified the Mini Guardian’s correct location each time. On average, it took us 20 seconds to reach a monitoring center agent.

Medical Guardian Third-Party Customer Reviews 

The company is accredited by BBB and has an A+ rating, but it has 1.14/5 stars based on 50 customer reviews as of writing. A majority of negative reviews cite cancellation issues or malfunctioning equipment. There is one positive review for Medical Guardian’s quick response and emergency services dispatch. MobileHelp does not have a listing on Trustpilot, but it has 4.5/5 stars based on over 274 Google Reviews as of writing. Positive reviews mention specific customer service representatives that made the sales process enjoyable and informative. MobileHelp replied to all negative reviews, and a majority of complaints were cancellation issues or receiving incorrect equipment.

  • Cost: $34.95 per month 
  • Connection type: Cellular
  • Device range: 1,400 feet 
  • Fall detection: Yes, $11 per month

The MobileHelp Classic is an at-home PERS system and includes a base station, help button wristband or necklace, and a lockbox.

A lockbox stores a house key for EMTs to use in case you can’t open or unlock your door during an emergency. You’ll choose a four-digit lockbox code when ordering your medical alert system, and the monitoring center agent will have the code on file to share with emergency services if needed. Most companies charge a one-time or monthly fee for a lockbox, but MobileHelp includes it free with all orders.

The help button connects to the monitoring center up to 1,400 feet (the length of over four football fields) from the base station, earning it “Best At-Home Range” for the MobileHelp Classic. Since ranges can be inconsistent, you may want to test your help button at various distances away from your base station. Your connectivity may vary depending on your location, similar to our recommendation for the Bay Alarm at-home system. 

The MobileHelp Classic was easy to install since the base station and help button were already connected and didn’t need to be activated. After plugging in the system, we followed a simple two-step testing process using the Quick Start Guide. The base station speaker is loud and clear when speaking with a monitoring center agent—they could hear and speak with us from the next room. The base station speaker also announces different device statuses, such as “system ready,” “power detected,” and “power not detected.” 

We were impressed with MobileHelp Classic’s quick response time: It took us 12 seconds to reach a monitoring center agent.

MobileHelp Third-Party Customer Reviews

MobileHelp is an A+ accredited business by BBB with 4.7/5 stars from customer reviews as of writing. Recent positive reviews spoke highly of MobileHelp’s customer service representatives during the sales process. One reviewer specifically mentioned how easy it was to set up and test the MobileHelp Classic. Most negative reviews cited cancellation issues. MobileHelp responded to all negative reviews. 

The brand isn’t on Trustpilot, but the company has 274 reviews on Google with 4.5/5 stars as of writing. Reviews detailed positive interactions with customer service representatives and praise over how easy set-up was, while the more negative reviews focused on issues with cancellation.

  • Cost: $29.95 per month
  • Connection type: Cellular
  • Device range: 1,000 feet 
  • Fall detection: $10 per month (plus $30 one-time equipment fee)

Our team named Bay Alarm Medical’s In-Home Preferred emergency response system as “Best Pricing Options” because of its affordable monthly monitoring cost compared to the at-home models in our review. While MobileHelp’s and Aloe Care Health’s at-home PERS units have similar monitoring fees to Bay Alarm Medical, both brands charge hefty equipment or processing fees on top of the monthly cost. 

Bay Alarm’s In-Home Preferred package includes a base station with a two-way speaker, a help button, and a lanyard and wristband for the button. The base station design is simple: It has one button at the top labeled HELP to contact the monitoring center. We like that the button is large, red, and easy to push, which is especially helpful for users who are visually impaired or experience reduced dexterity.  

Setup and testing instructions were clear, and it took only four steps to set up the base station. To test distance, we pressed the help button lanyard from the other end of the house (about 100 feet from the base station), and were able to speak with an agent from the base station speaker. Bay Alarm Medical advertises that you can connect to the monitoring center with the help button from up to 1,000 feet from the base station, but the farthest we were able to connect was 600 feet. Test your system’s full coverage range by pressing your help button from multiple locations inside and outside your home. Remember to always confirm with the agent that you’re testing the system—you won’t be penalized for multiple tests. 

On average, it took 37 seconds to connect to the monitoring center based on multiple tests. During an emergency, the monitoring center agent will dispatch emergency services and notify the emergency contacts listed in your online portal or Bay Alarm Medical app. 

Bay Alarm Medical Third-Party Reviews

Bay Alarm Medical has 4.1/5 stars on Trustpilot based on over 900 reviews as of writing. While almost 90% of reviews are five- or four-star reviews, the most recent reviews are from 2020. Positive reviews praise the company’s affordable prices and excellent customer service. Most negative reviews note trouble canceling the service and equipment not working properly. Bay Alarm Medical has an A+ rating from Better Business Bureau (BBB) with 4.26/5 stars based on 140 reviews as of writing. Many reviewers are happy with customer service and how quickly emergency services arrived when they contacted the monitoring center. Cancellation issues were the main complaint in negative reviews.

  • Cost: $35.99 per month 
  • Connection type: Cellular 
  • Device range: 600 feet 
  • Fall detection: Yes, $10 per month

We labeled the Medical Alert Plus “No Additional Fees” because ADT does not charge activation, equipment, or shipping fees. You’ll only pay for monthly monitoring and optional add-on features. The Medical Alert Plus is an at-home system with a help button pendant or wristband that connects up to 600 feet from the base station. When ordering the system, we also added the optional fall detection lanyard to our package. A small pendant is attached to a thin cord and worn around the neck. The fall detection pendant has a blue button in the center and is slightly larger than ADT’s standard help button pendant.

To set up the base station and fall detection lanyard, the product manual walked us through four easy steps. Unlike most PERS devices that arrive already connected to the monitoring center, we had to call ADT to activate our equipment. The customer service representative activated both systems and instructed us to do a fall detection lanyard drop-test over the phone to make sure it was working properly. We also tested the fall detection lanyard from sitting and standing positions, and the device detected a fall each time. The base station speaker announced, “fall detected, press and hold button to cancel,” and we canceled the call by pressing the button for two seconds. On average, it took 37 seconds for the monitoring center to respond from the base station.  

The Medical Alert Plus has built-in indoor temperature monitoring for extreme indoor temperatures. If your home temperature is less than 35 degrees or more than 105 degrees Fahrenheit, the base station will verbally alert you. A monitoring center agent will immediately dispatch emergency services to your home if they can’t get in touch with your or your primary emergency contact. 

ADT Third-Party Customer ReviewsIt’s difficult to find relevant reviews for ADT’s personal emergency response systems since most third-party review sites focus on the company’s home and commercial security systems. The company is listed as “ADT Home Health” on Best Company. It has 4.1/5 stars based on more than 20 reviews as of writing. Many positive reviews praised ADT’s professional, friendly, and helpful customer service representatives. Other reviewers mentioned the fast response time of their systems and monthly check-in calls from the company. Negative reviews cited false alarms, cancellation issues, and incorrect information from customer service representatives.

  • Cost: $29.99 per month + $149.99 equipment fee 
  • Connection type: Cellular 
  • Device range: 200 feet 
  • Fall detection: N/A

While Aloe Care Health’s voice-activated base station (Smart Hub) is unique compared to many standard PERS devices, the app is the true highlight. We named Aloe Care Health’s at-home Essentials system “Best App for Remote Caregivers.”

The app features: 

  • Base station battery and connection status 
  • Health card with medications, allergies, pre-existing conditions, and other health info that can be added from the app
  • Outside and home temperature monitoring 
  • Indoor monitoring of carbon dioxide (CO2) and volatile organic compounds (VOC) levels

In-app view of the Smart Hub’s connection status, voice calls, and settings

Caregivers can use the app to call their loved ones on the Smart Hub for a hands-free conversation. It doesn’t matter if your caregivers live close or hundreds of miles away: Up to four people can be added to the app to help coordinate care and check in on your safety and well-being.

The Essentials package includes the Smart Hub and a help button to place on a wristband or lanyard. When plugged into the base station, the Smart Hub will greet you with a recorded message that instructs you on which buttons to press for actions like calling the monitoring center, speaker volume control, and calling programmed contacts. 

The help button connects up to 200 feet from the Hub and doesn’t require additional activation. You can also contact the monitoring center by saying, “emergency,” four to five times. Voice activation was somewhat unreliable when we tested this model, with the Smart Hub calling the monitoring center multiple times randomly during our test period, even though we didn’t say, “emergency.” Conversation, television, and other audio may also activate the Hub. On average, it only took about 17 seconds to connect to the monitoring center.

Unfortunately, fall detection is not available with the Essentials package. 

Aloe Care Health Third-Party Customer ReviewsAloe Care Health doesn’t have a Better Business Bureau listing or Trustpilot page. The brand has 4.7/5 stars on Google Reviews based on 13 positive reviews as of writing. Reviewers mentioned the company’s helpful customer service and large, “elderly-friendly” buttons. Aloe Care Health responded to all reviews.

Older Adults Have a Higher Risk of Falling

Adults over 60 years old have the largest number of fatal falls, according to the World Health Organization. The National Institute on Aging cites low vision, impaired hearing, and slower reflexes as common causes of falls in older adults. Certain health conditions, such as complications from diabetes and medications used to treat heart disease, can also increase the likelihood of falling. 

While personal emergency response systems can’t prevent falls, they can reduce the “lie time” and complications that can arise from prolonged immobility after a fall by connecting you to emergency responders, so you can get medical attention as soon as possible.

Benefits of a Personal Emergency Response System

Personal emergency response systems connect you or your loved one to a 24/7 monitoring center during any emergency. You’ll be able to speak directly with a trained agent who can dispatch emergency services and contact your loved ones. If you’re unable to speak or are unresponsive, the agent will immediately send emergency responders to your location. 

“An important conversation is getting a feel for approximate wait times for emergency personnel to arrive. Rural and urban areas are often going to have differences in response/arrival time,” said Christopher Norman, a geriatric nurse practitioner, gerontologist, and advanced practice holistic nurse at PACE CNY. “It’s an important distinction, because signaling help and help actually arriving are two different things—and big considerations when talking about safety and aging in place.”

Other benefits of PERS systems include fall detection, medication reminders, home temperature monitoring, location tracking, activity monitoring, and more.

PERS Are More Affordable Than In-Person Monitoring

Some caregivers may view assisted living facilities or in-home care as the only options for their loved ones, especially if they have mobility or cognitive challenges. While everyone’s situation is unique, PERS monitoring can be an affordable caregiving solution for many older adults. 

The Department of Health and Human Services reported the average cost for the following long-term care: 

  • $253 per day for a private room in a nursing home
  • $119 per day for care in an assisted living facility
  • $68 per day for adult day health care services
  • $20.50 per hour for a home health aide

The average monthly cost of our best PERS monitoring devices is $33.17 per month, which breaks down to only $1.10 per day for 24/7 monitoring and additional caregiver tools.

Older Adults Retain Greater Independence 

Staying in your home brings a sense of independence, comfort, and familiarity. An AARP survey found that 76% of older adults in the U.S. want to age in their homes. A PERS device offers safety monitoring that allows older adults to stay in their homes without significantly altering their lifestyle or their caregivers’ routines. 

Immediate Response, Anytime

Personal emergency response devices are constantly connected to a monitoring center with agents on-call 24 hours a day, every day of the year. No matter what time of day you have an emergency, you will get help when you contact the monitoring center with your PERS.

Greater Peace of Mind

Personal emergency response systems can give both older adults and caregivers peace of mind and navigate the challenges of aging at home. According to an AgingInPlace.org survey, 90.8% of people feel more confident performing daily activities knowing their PERS device will provide them with immediate assistance.

Simple to Use 

Generally, personal emergency response systems are straightforward: You push a button and connect to the monitoring center. If your PERS device has fall detection, the fall detection device, often attached to a lanyard, will contact the monitoring center if it senses a fall. 

Most of the models featured here are “plug and play” devices, meaning we were able to use the system after plugging it in and following only three to four steps. Additional features such as medication reminders, home temperature monitoring, and location tracking are often monitored in the online dashboard or app. If you or your loved one is the primary PERS user and isn’t comfortable handling the online account, designate a family member or friend to handle the online dashboard or app. “After every health care appointment, hospitalization, and at least once a month, I advise people to cover changes that may occur in medications or other health routines,” added Norman.

Customer service representatives are also available to help with any issues over the phone or even through online chat.

Help at Home or On the Go 

Choose from at-home or mobile PERS devices. A home emergency response system plugs into your wall and connects to the monitoring center via an active landline or cellular connection. While you can still connect to the monitoring center with a wearable help button up to hundreds or over 1,000 feet from your base station, your connection to the monitoring center is limited to your home.

At-home PERS units are excellent if you have limited mobility, stay in your home the majority of the time, or are always with a companion when you’re outside your home. 

Mobile systems work anywhere with cellular service. If you’re more independent and enjoy driving, running errands, and other activities on your own, you can take a mobile personal emergency response system with you anywhere and stay connected to the monitoring center. 

Mini Guardian is the only mobile PERS listed in our review, but all brands featured here have a mobile system option.

Why Cellphones Aren’t the Best Option for Personal Emergency Responses

Some may argue that personal emergency systems are unnecessary if you have a cell phone. While cell phones are convenient to keep in touch with loved ones or call 911 during an emergency, they have limitations compared to PERS monitoring devices. 

Your location may be harder to track when calling 911 compared to PERS GPS tracking. The Federal Communications Commission (FCC) is improving the location accuracy of 911 calls, but the FCC still encourages callers to give operators their exact location. This may not be possible if you’re unaware of your surroundings or are having trouble speaking with the operator during an emergency. Most PERS devices have built-in GPS tracking, so monitoring center agents can see your exact location coordinates during a call. 

Cell phone buttons or a touchscreen may be difficult to push and navigate during an emergency. PERS devices have large, central buttons that are designed to be pushed easily. Almost all personal emergency systems have a wearable option, such as a bracelet or necklace, so the help button is within reach at all times. If your cell phone is buried in your purse or pocket, it may be difficult to reach during a medical emergency.

Some devices advertised as personal emergency response systems are not monitored by a 24/7 monitoring center. Instead, the device is programmed to dial 911 or emergency contacts. 

The AgingInPlace.org team recommends purchasing a PERS that is connected to a 24/7 monitoring center. All our best personal emergency response system choices and top medical alert systems feature 24/7 monitoring. 

The right personal emergency response system is different for everyone and should be based on activity level, caregiving needs, and personal preferences. Keep the following in mind when shopping for a PERS device.

Fall Detection

Fall detection is an optional safety feature available for most at-home and mobile PERS devices. A system with fall detection has built-in motion sensors for detecting falls. If the motion sensors are triggered by a fall or fall-like movement, the system automatically connects to the monitoring center.

Smoke, Fire, and Carbon Dioxide Detection

PERS devices are commonly used for medical emergencies and falls, but some systems also detect extreme indoor temperatures and poor air quality. 

Usually, only extreme temperatures, such as from smoke or fire, trigger the system’s sensors. If your indoor temperature goes below or above the system’s “safe” range, the device will either automatically contact the monitoring center or send an app notification to the user and caregivers. 

ADT and Aloe Care Health offer PERS units with indoor temperature monitoring, but Aloe Care Health systems also monitor indoor air quality. The Smart Hub measures carbon dioxide (CO2) and volatile organic compounds (VOC) levels and alerts caregivers via the Aloe Care app if indoor CO2 and VOC levels are too high.

Most VOCs are human-made chemicals commonly found in paint, cleaning products, aerosols, and more, according to the Environmental Protection Agency. VOC exposure can be dangerous depending on the level and length of exposure.

Medication Compliance

Medication reminders are becoming a more common PERS feature since they can be set by caregivers in an app instead of pre-programmed in the device. Depending on the PERS unit, you’ll either receive an alert from the system or from the app letting you know it’s time to take your medication. 

Fitness and Activity Monitoring 

Fitness tracking and activity monitoring are two different features, although they sound similar. Select mobile PERS systems (especially smartwatch personal emergency systems) have built-in step trackers to help wearers monitor daily physical activity goals. 

Activity monitoring allows caregivers to make sure their loved one is comfortably moving around throughout the day. Movement is tracked either with motion sensors, like Aloe Care Health’s Smart Hub, or with a standard push-button check-in from the base station. Caregivers will receive an alert if your loved one’s movement patterns change or stop. 

GPS Monitoring 

For older adults using an on-the-go system, GPS monitoring is a crucial safety feature. Caregivers can check their loved one’s location with a mobile system’s built-in GPS location tracking. We like that Medical Guardian’s app integrates with Google Maps, allowing us to see the location of our Mini Guardian device on Google Maps at all times.

If you or your loved one contacts the monitoring center outside the home, the agent will be able to dispatch emergency services to your exact location coordinates using GPS technology. GPS monitoring is also helpful if your loved one is prone to wandering or if the device is frequently misplaced outside the home.

A personal emergency response system costs $20–$55 per month on average. This cost varies by brand, model, and additional features. Generally, in-home systems are less expensive than mobile systems. You’re usually charged a one-time equipment fee for mobile systems, such as the $149.95 fee for the Mini Guardian. Fall detection is almost always an optional monthly fee. 

PERS systems aren’t covered by Traditional Medicare (Part A and B) or Medicaid, but Medicare Advantage (Part C) may cover some costs. Check with your insurance provider for details, since Medicare coverage varies by state. 

Some companies offer discounts on monitoring fees, fall detection, or even waive additional fees for a limited promotional period.

How to Choose the Best Emergency Response System for You

The best emergency response system for you depends on your caregiving needs, personal preferences, activity level, and more.

Consider the following when choosing the best PERS alert system for you or your loved one: 

  • At-home or mobile system
  • Connection type and response time 
  • Cost
  • Warranty and trial periods
  • Company reputation 
  • Key features: battery life, water resistance, help button accessibility, style, and comfort 
  • Optional features: fall detection, voice activation, medication reminders, temperature monitoring, wellness checks, and more

The right personal emergency response system will vary for everyone. If you’re a caregiver and your loved one is hesitant to use a PERS, empower them by including them in the shopping process—and consider including a qualified health care professional, like a nurse, physical therapist, or occupational therapist, noted Norman.

Many PERS devices have a 30-day money-back guarantee policy. Encourage your loved one to test the device during this period and discuss their concerns, preferences, and other feedback before fully committing to a personal emergency response system subscription.
