How to Choose a Medical Alert System for Seniors

A medical alert system is a device that lets you call for emergency help quickly — often when you cannot reach a phone. These systems are especially valuable for older adults who live alone, have had falls in the past, or have health conditions that could lead to a sudden emergency.

The core of every medical alert system is a button connected to a 24/7 monitoring center staffed by trained operators. When you press the button, you are immediately connected to a live person who can assess the situation and dispatch emergency services — ambulance, fire, or police — to your location, even if you cannot speak clearly.

There are three main types to choose from.

Home-based systems include a base unit plugged into a wall outlet in your home, connected via a landline or cellular signal. You wear a small button on a lanyard around your neck or on a wristband. These buttons typically work within 600 to 1,500 feet of the base unit, which covers most homes and yards. Home-based systems are the most affordable, often $20–30 per month.

Mobile or GPS systems work anywhere, not just at home. A small device you carry or wear communicates over cellular networks and includes GPS so the monitoring center can pinpoint your location outdoors — at the grocery store, on a walk, or traveling. These run $30–45 per month.

Smartwatch-style systems look like a regular wristwatch and include cellular calling, GPS, and fall detection built in. These are the most discreet option.

Fall detection is an important feature to understand. With fall detection, the device can sense a hard fall automatically and alert the monitoring center — even if you are unable to press the button. This matters because falls often involve head injuries that leave the person disoriented or unconscious. Not all systems include fall detection, and it sometimes adds to the monthly cost.

All systems should be water resistant so they work in the shower — where a significant number of falls occur.

Leading providers include Life Alert (well-known brand, requires a contract), Medical Guardian (no contract, strong mobile options), Bay Alarm Medical (affordable, no contract), and Apple Watch Series 9 or later (fall detection built in, works with Emergency SOS). For people already comfortable with Apple Watch, this can be the most integrated solution.

Questions to ask before buying: Does it work in the shower? Is fall detection included? Is there a long-term contract? What is the battery life? Is there a trial period?
