ADT vs. CPI Security Review
The home security market now defaults to hybrid options: self-setup hardware with optional pro monitoring alongside traditional professional installation. ADT spans both models nationally (professional install plus Self Setup), while CPI Security focuses on professionally installed systems within the Southeast. Customer priorities in recent research emphasize cost transparency, reliable monitoring, and strong apps over legacy distinctions (J.D. Power 2024). Both providers lean into smart-home ecosystems rather than one-off gadgets—ADT with Google Nest via ADT+, and CPI via the Alarm.com-powered inTouch platform.
If you want pro monitoring with modern smart-home control, both brands qualify but differ in scope and approach. ADT brings nationwide coverage, verified-response tools in ADT SMART Monitoring, and the Google Nest bundle path via the ADT+ app (ADT + Google). CPI operates regionally with its Real Time Response verification workflow and in-market technicians. Promotions rotate for each—commonly free installation, camera credits, or bill incentives—so confirm the current details on the official pages before purchase (ADT Packages; CPI Security).
ADT vs. CPI Security Overview
| ADT | CPI Security | |
| Basic monthly pricing | Professional install is quote-based; Self Setup publishes online tiers (DIY monitoring commonly ~$20–$30/mo in market—confirm current ADT Self Setup rates online) | Quote-based by consultation; promos often bundle free install or camera credits in-footprint |
| Installation | Professional nationwide; or Self Setup (DIY). Install/activation fees may apply; promos can waive | Professional only; installation fees often waived during promotions |
| States covered | Nationwide availability (check local permitting and service) | 8 (Southeast service area) |
| Theft protection | ✓ Theft Protection Guarantee (deductible reimbursement; eligibility applies) | ✓ Verified-response focus; review CPI guarantees (false-alarm and service policies) |
| Terms | Pro install typically multi-year; Self Setup monitoring has no long-term contract | Typically multi-year agreements; confirm term length, renewal, and early-termination provisions |
Shopping experience
ADT sells professionally installed systems via phone/consultation and also lets you order Self Setup online with transparent equipment bundles and monitoring options. CPI primarily quotes by consultation within its service footprint. Expect rotating promos (free install, discounted cameras, bill credits) tied to specific monitoring tiers and term commitments (ADT offers; CPI current offers).
When collecting quotes, ask for the total, all-in price and length of commitment. Regulators are pushing clearer, single-price displays and easier cancellations in many sectors—California’s “junk fee” law requires showing the full price up front for most offers (California SB 478 guidance). Clarify installation/activation fees, video storage add-ons, and whether service or repair coverage is included in the base plan.
Unique offers
Both providers market verification-focused monitoring to speed dispatch and reduce false alarms. ADT’s SMART Monitoring includes digital workflows like Alarm Messenger to confirm alarms faster. Hardware packages often integrate Google Nest cameras, doorbells, and thermostats in the ADT+ app (ADT+ app).
ADT also advertises a Theft Protection Guarantee that can reimburse part of your deductible if a burglary occurs while the system is armed (eligibility and caps vary by plan and state—see ADT terms).
CPI emphasizes Real Time Response with audio/video verification and two-way voice. CPI offers an extended service option often called a Service Plus program that covers parts and labor for enrolled customers; verify coverage, fees, and exclusions on CPI’s current pages. CPI also promotes a No False Alarm Guarantee that reimburses municipal false-alarm fines when a CPI-caused malfunction triggers dispatch; reimbursement limits and eligibility are specified on CPI’s legal/offer pages—confirm the current per-incident cap and any annual limits before you buy (CPI Security).
Smart home capabilities
ADT’s current ecosystem centers on ADT+ with Google Nest devices for cameras, doorbells, displays, and thermostats. CPI’s inTouch app runs on the Alarm.com platform with broad support for Z‑Wave accessories (locks, lights, sensors) and a curated camera lineup. Interoperability is improving through the Matter 1.3 standard, but neither brand’s system implies universal Matter support: many security devices still rely on platform-specific integrations, and full camera functionality in Matter is still evolving. For multi-camera homes, next‑gen Wi‑Fi 7 can improve reliability and latency for high‑resolution streaming.

How to Compare Home Security Providers
Smart home features
The best home security systems combine intrusion and life‑safety protection with reliable apps and integrations. Recent satisfaction research highlights cost, ease of use, app quality, and dependable support/monitoring as top drivers—smart‑home features contribute materially to overall satisfaction (J.D. Power 2024). Interoperability continues to improve with Matter 1.3, though advanced categories like full‑featured cameras may still require platform‑specific integrations.
Consider which ecosystem you already use. ADT’s ADT+ aligns with Google Nest devices, while CPI’s inTouch (Alarm.com) supports a broad mix of Z‑Wave and third‑party gear. For mixed households, Matter‑certified devices can reduce lock‑in across Apple, Google, Amazon, and SmartThings ecosystems, but verify device‑type support and feature parity in your chosen platform (CSA: Matter).
DIY vs Professional
DIY systems emphasize lower monthly costs and contract‑free flexibility, while professional systems deliver turnkey design, installation, and UL‑listed central‑station monitoring. The lines are blurring: ADT offers both pro install and Self Setup with optional pro monitoring, whereas CPI focuses on professional install. Typical DIY monitoring runs about $20–$30/month across the market, while professionally installed plans commonly start in the mid‑$40s and scale with smart‑home/video features (ADT pricing overview; SimpliSafe plans; Ring Alarm monitoring). If UL 827 central‑station monitoring and verified response are priorities, professional plans provide that framework (UL 827).
Contract terms
Many complaints in this category stem from contract misunderstandings—term length, early‑termination fees, and cancellation steps—reflected in public reviews for both brands (ADT BBB; CPI BBB). Get the term, renewal policy, and ETF formula in writing. Emerging consumer rules in adjacent sectors are pushing clearer pricing and simpler cancellation (e.g., U.S. “junk fee” bans on drip pricing in California and regulatory actions targeting hidden cancellation fees) (California SB 478; DOJ/FTC Adobe case).
ADT vs. CPI Security FAQ
What’s the difference between ADT monitoring and CPI Security monitoring?
Both brands use 24/7 professional monitoring. ADT’s SMART Monitoring layers in digital verification tools (e.g., Alarm Messenger) to help reduce false dispatch and accelerate response, while CPI’s Real Time Response emphasizes audio/video verification and two‑way voice. Professional monitoring can also help you qualify for “protective device” discounts on homeowners insurance; many carriers still offer modest credits for centrally monitored alarms—ask your insurer about eligibility and documentation (Insurance Information Institute; Travelers; State Farm).
Do both ADT and CPI Security offer smart home integration?
Yes, with different ecosystems. ADT’s ADT+ app integrates closely with Google Nest cameras, doorbells, and thermostats (ADT+ app). CPI’s inTouch (Alarm.com) supports a broad range of Z‑Wave devices and CPI‑curated cameras. Matter is improving cross‑platform control across Apple, Google, Amazon, and SmartThings, but camera feature parity and some device types still rely on platform‑specific integrations—verify your exact devices and needed features (CSA: Matter 1.3).
Can I move with ADT and CPI Security home security systems?
Yes, but policies differ. CPI supports moves within its eight‑state service area (Alabama, Florida, Georgia, Maryland, North Carolina, South Carolina, Tennessee, Virginia) with professional installation; installation fees and promos vary by offer (CPI Security). ADT offers relocation options for professionally installed systems and discounts for movers, and Self Setup equipment can be moved and reactivated more easily—confirm applicable fees, any new‑term requirements, and permit needs with your local branch.
