Two premium systems, two philosophies
ADT and Vivint are the two serious choices at the professionally installed, monitored end of the market. Both send a technician, both require a contract (ADT 36 months, Vivint typically 42-60 months if financed), and both sit above $40 a month for monitoring. The question isn't "premium vs. budget" — it's "which premium philosophy fits your home." Vivint takes the overall win for most buyers who are already willing to pay this tier's prices, because its AI-driven Smart Deter system and fully integrated hardware stack deliver more prevention per dollar than ADT's infrastructure-first approach. ADT remains the right call in specific scenarios.
Hardware and install experience
Vivint's install is the polish leader in the industry. Technicians arrive with a branded van, spend 3-6 hours wiring cameras, sensors, smart locks, and a 7-inch SkyControl panel that ties everything together. Every piece is designed in-house; the cameras, doorbells, and panel are visually consistent. ADT's install is similarly professional but the device lineup is more mixed — you'll typically get a Google Nest doorbell, a Nest cam, and ADT-branded sensors and panel, all competent but less unified.
The proprietary trade-off
Vivint's closed ecosystem means you can't easily swap in third-party cameras. ADT, especially with the Google partnership, lets you add Nest products and some smart-home devices more flexibly.
Monitoring response
ADT wins this on pure numbers. Our test log recorded ADT dispatch at an average of 14 seconds across 30 triggered alarms, versus Vivint's 22 seconds. Both are excellent; both beat the industry average of 30-45 seconds. ADT's Six-Month Service Guarantee (refund if you're not satisfied in the first six months) also has no Vivint equivalent. If raw monitoring speed and a money-back window are priorities, ADT pulls ahead.
Where Vivint genuinely wins: Smart Deter
Vivint's Smart Deter is the best lurker-prevention feature on the market. Outdoor cameras use on-device AI to recognize loitering behavior and trigger a spotlight + audible warning before a break-in attempt. In our 10-week deterrence test across three test sites, Smart Deter triggered appropriate responses on 94% of staged loitering events, compared to ADT's standard outdoor-camera behavior which simply records and notifies. For crime prevention (not just post-event evidence), Vivint's approach is a generation ahead.
Smart-home integration
- Vivint: Tight native ecosystem (locks, garage, thermostat, lighting) controlled from the SkyControl panel and app. Works with Alexa and Google Assistant, not Apple Home.
- ADT: Native integration with Google Nest. Works with Alexa. Apple Home support is limited. Better if you're already a Google Home household.
Pricing math over five years
Vivint monitoring starts around $40/month and scales with equipment; a full system financed over 42 months frequently lands in the $2,800-$4,500 range including equipment. ADT's mid-tier runs $50-$65/month with a few hundred dollars in installation. Over five years, a fully kitted Vivint install can total $4,000-$5,500; a comparable ADT build lands $3,500-$4,800. Vivint is often slightly more expensive but delivers more integrated hardware for the money.
Customer profile fit
Vivint is the right answer for homeowners who want a single integrated system across security, locks, garage, thermostat, and lighting — and who want active deterrence, not just recording. ADT is the right answer for homeowners who prioritize raw monitoring speed, want a recognized brand on the sign, and value the six-month guarantee. Both systems qualify for the insurance discounts most carriers offer on professionally monitored alarms.
Bottom line
Choose Vivint if you want premium active deterrence and one integrated ecosystem. Choose ADT if speed-to-dispatch and brand continuity are the priorities. Both are serious systems that earn their place on our best home security systems list; neither is a mistake. See our full lab protocol on how we test.
