SimpliSafe vs ADT 2026: Budget DIY Alarm vs America’s Oldest Security Brand
SimpliSafe is a no-contract DIY security system with equipment starting at $250, free self-monitoring, and professional monitoring from $19.99/month. ADT is the largest home security company in America with 150+ years of history, Google Nest integration, and plans from $28.99/month.
Both companies target mainstream homeowners, but they take different approaches to price, installation, and smart home integration. Here’s how they compare in 2026.
Quick Comparison
| Feature | SimpliSafe | ADT |
|---|---|---|
| Monthly Cost | $0 (self) to $29.99/mo | $28.99 to $59.99/mo |
| Contract | None | None (Self Setup) or 36 months |
| Installation | DIY (20–30 min) | DIY or professional ($100+) |
| Equipment | $250–$734 (kits) | $99–$500+ |
| Self-Monitoring | Free (limited) | Not available |
| Pro Monitoring | $19.99–$29.99/mo | $28.99–$59.99/mo |
| Cameras | 3 models (indoor, outdoor, doorbell) | Nest cameras (indoor, outdoor, doorbell) |
| Cellular Backup | Yes (all monitored plans) | Yes (all plans) |
| Apple HomeKit | No | No |
| Smart Home | Alexa, Google (limited) | Alexa, Google (deep Nest) |
| 3-Year Cost | $250–$1,330 | $1,142–$2,359 |
Where SimpliSafe Wins
1. No Contracts
Every SimpliSafe plan is month-to-month. Cancel anytime, no early termination fees. ADT’s traditional plans require 36-month contracts — cancel early and you owe 75% of the remaining balance.
2. Lower Cost Across the Board
SimpliSafe’s professional monitoring starts at $19.99/month vs ADT’s $28.99. Over 3 years with monitoring, SimpliSafe costs $970–$1,330 vs ADT’s $1,142–$2,359. That’s $170–$1,000 in savings depending on tier.
3. Free Self-Monitoring
SimpliSafe offers a free tier with app alerts and basic system control. ADT requires a paid plan for any functionality. If you just want alerts when a door opens, SimpliSafe costs $0/month.
4. Retail Availability
SimpliSafe sells through Amazon, Best Buy, Target, and its own website. You can buy a system today and set it up tonight. ADT’s traditional path requires scheduling a consultation and installation appointment.
5. Better Camera Lineup (vs ADT Self Setup)
SimpliSafe’s own cameras (indoor, outdoor, Video Doorbell Pro) work natively with the system. ADT Self Setup has limited first-party camera options. ADT’s traditional tier uses Nest cameras, which are better — but cost more.
Where ADT Wins
1. Google Nest Camera Ecosystem
ADT’s partnership with Google gives you Nest cameras, Nest Doorbell, and Nest thermostats in one unified system. SimpliSafe’s cameras are decent but can’t match Nest’s AI-powered features, 4K resolution, or familiar interface.
2. Brand Recognition for Insurance
ADT’s 150+ year history and market dominance mean some insurers offer the highest discounts (10–20%) specifically for ADT systems. SimpliSafe qualifies for discounts too, but ADT’s name carries more weight.
3. Professional Installation
ADT technicians assess your home, choose optimal sensor placement, and handle all wiring and setup. SimpliSafe is DIY only. For complex homes or less tech-savvy buyers, this matters.
4. Larger Monitoring Network
ADT operates the largest monitoring center network in the US with multiple redundant facilities. SimpliSafe uses COPS Monitoring — reputable, but not as extensive.
3-Year Cost Breakdown
| Setup | Equipment | Monthly | 3-Year Total |
|---|---|---|---|
| SimpliSafe Free | $250 | $0 | $250 |
| SimpliSafe Standard | $250 | $19.99 | $970 |
| SimpliSafe Fast Protect | $250 | $29.99 | $1,330 |
| ADT Self Setup | $99 | $28.99 | $1,143 |
| ADT Smart | $199 | $45.99 | $1,855 |
| ADT Complete | $199 | $59.99 | $2,359 |
SimpliSafe’s most expensive plan ($1,330/3yr) still costs less than ADT’s cheapest ($1,143/3yr). For budget-conscious buyers, SimpliSafe wins on math alone.
The Third Option: Abode
Neither SimpliSafe nor ADT supports Apple HomeKit, Z-Wave, Zigbee, or Matter. If smart home integration matters, Abode covers all four protocols plus Alexa and Google — with free self-monitoring, no contract, and pro monitoring from $6/month. A 3-year Abode setup costs $199–$919.
Who Should Buy SimpliSafe
- Budget-conscious buyers — cheaper than ADT on every tier
- No-contract shoppers — cancel anytime without penalty
- DIY installers — quick setup from retail shelves
- Camera-focused buyers — 3 native camera models vs ADT Self Setup’s limited options
Who Should Buy ADT
- Insurance discount maximizers — ADT’s brand gets the highest rates
- Google Nest households — unified camera + alarm + thermostat
- Professional installation wanted — technicians handle everything
- Brand trust matters — 150+ years, largest US monitoring network
The Bottom Line
SimpliSafe is the better value for most DIY buyers — no contract, lower cost, free self-monitoring, and retail availability. ADT is the pick if you want professional installation, Google Nest cameras, or maximum insurance discounts. And if neither offers the smart home depth you need, Abode bridges the gap with HomeKit, Z-Wave, Zigbee, and Matter support at an even lower price point.

FAQs
Is SimpliSafe as good as ADT?
For monitoring reliability, both are solid — SimpliSafe uses COPS Monitoring, ADT has its own centers. SimpliSafe’s equipment is less premium than ADT’s Nest-powered setup, but costs significantly less. For DIY buyers, SimpliSafe offers better value. For hands-off buyers who want pro install and Nest cameras, ADT has the edge.
Does SimpliSafe or ADT work with HomeKit?
Neither supports Apple HomeKit. The only major security system with HomeKit is Abode.
Can I cancel SimpliSafe anytime?
Yes — all SimpliSafe plans are month-to-month with zero cancellation fees. ADT Self Setup is also no-contract. ADT’s traditional plans require 36 months.
Which gives better insurance discounts?
Both qualify when using professional monitoring. ADT may get slightly higher discounts from insurers that specifically list the ADT brand. The difference is usually small — and SimpliSafe’s lower monthly cost often offsets any insurance gap.
Is ADT Self Setup worth it over SimpliSafe?
ADT Self Setup ($28.99/mo) and SimpliSafe Standard ($19.99/mo) are comparable DIY products. SimpliSafe is $9/month cheaper with better native cameras. ADT Self Setup’s main draw is the ADT name for insurance purposes. Over 3 years, that’s a $324 premium for the brand.
