ADT is the most trusted name in home security in America. The company has been operating for 150 years. Their home alarm systems protect millions of households. Their monitoring centres are established, US-based, and professionally staffed.
Their medical alert system inherits all of that brand trust — and adds something no competitor offers: a ForeveRate Price Lock Guarantee that ensures your monthly rate will never increase for as long as you are a customer.
That is a genuinely unusual offer in a category where providers quietly raise rates after the first year. It is also the single strongest reason to choose ADT Medical Alert over comparable alternatives in 2026.
The single thing it is missing is worth knowing upfront: ADT Medical Alert has no caregiver companion app. No GPS tracking for family members. No emergency notifications to a second person’s phone. For families where that connectivity matters, it is a dealbreaker.

ADT Medical Alert Systems — Three Plans
ADT offers three distinct systems. All three share core features: waterproof help buttons, 24/7 two-way monitoring, the ForeveRate Price Lock Guarantee, and ADT’s Premium Protection Plan which covers replacement for normal wear and tear at no cost.
Medical Alert Basic — $31.99 per month
The Basic plan is ADT’s in-home landline system. It includes a base station and a waterproof wearable device — available as a pendant or wristband. The pendant can be submerged to three feet for up to 30 minutes.
When the help button is pressed, the call connects through the base station’s speaker to one of ADT’s six US-based monitoring centres. If you press the button and cannot speak, ADT dispatches 911 immediately without waiting for a voice confirmation.
The Basic plan is the right choice for seniors who are primarily home-based and have a working landline.
Medical Alert Plus — $37.99 per month
The Plus plan adds cellular connectivity — no landline required — and a distinctive feature: temperature monitoring. The base station monitors ambient room temperature and alerts the monitoring centre if the temperature rises or falls outside a safe range. For seniors living alone in climates with extreme summer heat or winter cold, this is a potentially life-saving feature that ADT is the only major provider to offer.
For most families, the Plus plan at $37.99 per month represents the strongest value point in ADT’s lineup — the cellular connectivity alone justifies the $6 per month premium over the Basic plan.
On-The-Go — $46.99 per month
ADT’s mobile system works anywhere with AT&T cellular coverage. It is approximately the size of a tea bag — one of the smallest mobile medical alert devices available. Built-in GPS tracks location in real time and shares it with the monitoring centre during an emergency.
The On-The-Go plan is appropriate for active seniors who travel, drive, or spend significant time outside the home. For primarily home-bound seniors, the Medical Alert Plus provides better value.
The Price Lock Guarantee — Why It Matters
ADT calls it ForeveRate. The commitment is simple: your monthly rate will never increase for the life of your subscription.
This is rare. Most medical alert providers reserve the right to adjust pricing with notice — typically 30 days. Rate increases after the first or second year are common in subscription services. ADT’s Price Lock removes that uncertainty entirely.
For seniors on a fixed income or families managing a tight monthly budget, the ability to plan around a guaranteed monthly figure — with no possibility of an unexpected rate increase — has real financial value. A $31.99 plan is $31.99 in year one, year three, and year seven.
No other major medical alert provider in 2026 offers an equivalent guarantee. Bay Alarm Medical explicitly notes that its rates are subject to change. Medical Guardian and LifeFone do not guarantee fixed pricing.
The fine print: the Price Lock applies to the base plan rate. Add-on services such as fall detection and the wall button add-on are not covered by the guarantee. Price changes to add-ons are theoretically possible.
ADT Medical Alert Pricing — All Costs Explained
Monthly billing rates are $31.99 for Medical Alert Basic, $37.99 for Medical Alert Plus, and $46.99 for On-The-Go.
Quarterly billing reduces each plan by $2 per month. Annual billing reduces each by $5 per month and adds free shipping and a free lockbox.
The $99 activation fee applies to all three plans and is charged at the time of purchase. This is a notable upfront cost — LifeFone, Bay Alarm Medical, and Medical Guardian all waive activation fees.
Fall detection is available as an add-on for $11 per month — $1 more than the $10 charged by both Medical Guardian and Bay Alarm Medical. The fall detection pendant is a separate wearable device, not a software feature of the existing help button.
An emergency wall button can be added for $2.99 per month — useful for mounting in the bathroom as a fixed backup to the wearable device.
ADT leases its equipment rather than selling it. The base station and devices remain ADT’s property. When you cancel service, equipment must be returned. There is no equipment purchase option.
First-year total on Medical Alert Plus with fall detection and monthly billing: $37.99 multiplied by 12 months equals $455.88, plus $99 activation, plus $11 per month fall detection multiplied by 12 months equals $132. Total first year: approximately $687.
ADT’s Premium Protection Plan is included at no cost with every subscription. It covers 100% replacement cost for damage from normal wear and tear, power surges, and manufacturing defects. Accidental damage is covered with a one-time deductible of an unspecified amount — check your subscriber agreement for the specific figure.
What We Like About ADT Medical Alert
Price Lock Guarantee — Industry Unique
No other major medical alert provider guarantees a fixed monthly rate. For families managing a fixed budget, this certainty is genuinely valuable and differentiates ADT from every alternative in this review series.
14-Second Average Response Time
ADT’s monitoring centres responded in an average of 14 seconds in independent 2026 testing. This is not as fast as Medical Guardian’s 8 seconds or Bay Alarm Medical’s 16 seconds, but it is dramatically faster than Life Alert’s 120 seconds and entirely appropriate for emergency response.
Six US-Based Monitoring Centres — Maximum Redundancy
ADT operates six monitoring centres across the United States. This redundancy means that if one centre is overwhelmed or experiences a technical issue, calls automatically route to another. No other medical alert provider in this review series matches this level of operational redundancy.
Premium Protection Plan — Free Replacement Coverage
The included Premium Protection Plan covers replacement for normal wear and tear without charge. Battery replacements are covered. Power surge damage is covered. This removes the anxiety of “what happens if the device breaks” that some families feel with other providers.
Temperature Monitoring on the Plus Plan
The Medical Alert Plus plan includes temperature monitoring as a standard feature — not an add-on. For seniors living alone in climates with extreme temperatures, this passive safety net has genuine value. No other provider in this review series includes temperature monitoring as standard.
150 Years of Brand Trust
For families where the senior is resistant to the concept of a medical alert system, ADT’s name recognition can lower that resistance. The brand is associated with home safety in a way no purpose-built medical alert company can replicate. This is not a technical feature, but it is a real factor in adoption.
What We Do Not Like
No Caregiver App on Any Plan
This is ADT Medical Alert’s most significant gap in 2026. Medical Guardian, Bay Alarm Medical, and Lively all include free caregiver apps that provide GPS tracking, battery monitoring, and emergency notifications to family members. ADT offers no equivalent at any price tier.
For families where an adult child wants to be notified when an emergency call is placed, track their parent’s location, or monitor device battery status, ADT cannot deliver this. This alone rules ADT out for a large portion of the market in 2026.
$99 Activation Fee
The upfront $99 fee is a meaningful cost that competitors have eliminated. When comparing monthly rates, factor in the first-year total including activation — ADT’s effective first-year cost is $99 higher than Bay Alarm Medical or Medical Guardian on equivalent plans.
Equipment Is Leased, Not Owned
ADT retains ownership of the base station and devices. On cancellation, equipment must be returned. For families who prefer to own the device outright, this is not the right model. For most families, leasing is a practical non-issue — the equipment is returned when service ends.
No Smartwatch Option
ADT does not offer a smartwatch-format medical alert device. Medical Guardian’s MGMove and Lively’s smartwatch plan serve seniors who prefer a wrist-worn device that looks like a consumer product. ADT has no equivalent.
Starting Price $4 Higher Than Bay Alarm Medical
At $31.99 per month, ADT costs $4 more per month than Bay Alarm Medical’s $27.95 entry point. Over a year, that is $48 more for comparable in-home monitoring — before factoring in ADT’s $99 activation fee versus Bay Alarm Medical’s zero activation fee.
ADT Medical Alert vs Medical Guardian
Monthly price: ADT $31.99 vs Medical Guardian $31.95. Essentially identical.
Activation fee: ADT $99 vs Medical Guardian $0. Medical Guardian wins.
Fall detection: ADT $11/mo vs Medical Guardian $10/mo. Medical Guardian wins.
Response time: ADT 14 seconds vs Medical Guardian 8 seconds. Medical Guardian wins.
Caregiver app: ADT none vs Medical Guardian free. Medical Guardian wins significantly.
Price lock: ADT guaranteed vs Medical Guardian no guarantee. ADT wins.
Redundant monitoring: ADT 6 centres vs Medical Guardian not specified. ADT wins.
Temperature monitoring: ADT Plus plan includes it vs Medical Guardian not offered. ADT wins.
For most families, Medical Guardian is the stronger technical choice. For families who specifically value the Price Lock Guarantee and temperature monitoring, ADT is defensible.

ADT Medical Alert vs Life Alert
Monthly price: ADT $31.99 vs Life Alert $69.95. ADT wins by $38/month.
Contract: ADT month-to-month vs Life Alert 36-month mandatory. ADT wins decisively.
Fall detection: ADT $11/mo add-on vs Life Alert not offered. ADT wins.
Response time: ADT 14 seconds vs Life Alert 120 seconds. ADT wins dramatically.
Activation fee: ADT $99 vs Life Alert $197. ADT wins.
Price lock: ADT guaranteed vs Life Alert not guaranteed. ADT wins.
3-year total: ADT approximately $1,250 vs Life Alert $2,715. ADT wins.
ADT outperforms Life Alert on every metric that matters. For a full Life Alert cost breakdown, see our Life Alert cost guide.
Is ADT Medical Alert Worth It in 2026?
For families where the senior values ADT’s brand trust, or where the Price Lock Guarantee provides meaningful budget certainty, ADT is a solid choice. The 14-second response time, six monitoring centres, temperature monitoring, and Premium Protection Plan are all genuine strengths.
For families where a caregiver app is a priority, ADT is eliminated — there is no workaround for the absence of this feature. Medical Guardian or Bay Alarm Medical are the alternatives in that case.
For families where budget is the priority, LifeFone at $24.95 per month on an annual plan provides equivalent core monitoring at significantly lower cost with no activation fee.
Best Alternative if ADT Is Too Expensive
LifeFone at LifeFone starts at $24.95 per month on an annual plan ($29.95/mo month-to-month) — $7 less per month than ADT — with no activation fee, no contract, a free caregiver app, and fall detection from $5/mo. The 30-day money-back guarantee makes it low-risk to try.

Our Recommendation
