ADT packages run $349 to $1,594, and its professionally installed systems typically carry a 36-month agreement.

SimpliSafe vs ADT on monitoring
Both brands offer 24/7 professional monitoring with cellular backup, and both score 9.8/10 with Security.org — so alarm response quality is not the deciding factor. The difference is the network and the flexibility. ADT operates six redundant monitoring centers and more than 150 years of history, the deepest infrastructure in the category. SimpliSafe delivers professional monitoring without any contract and with a free self-monitoring tier, which ADT only matches on its Blu line. For hands-off buyers who want the most established name, ADT edges it; for buyers who want to start monitoring with zero commitment, SimpliSafe leads.
SimpliSafe vs ADT on equipment and installation
SimpliSafe is DIY-first: you self-install a wireless system in under an hour, with optional professional installation available. ADT gives you both paths — self-install ADT Blu or a technician-installed Pro system. Hardware-wise, SimpliSafe covers the essentials (entry sensors from $15.99, cameras $149.99–$199.99) at a lower price, while ADT adds deeper smart-home integration, including Google Nest cameras inside the ADT+ app. If you value a polished smart-home ecosystem and professional setup, ADT is stronger; if you want simple, affordable, renter-friendly gear you can take with you, SimpliSafe fits better.
Definition — DIY vs professional install: with DIY (SimpliSafe) you mount and activate the system yourself; with professional install (ADT Pro) a technician designs, mounts, and tests it. DIY saves money and moves easily; professional install saves effort and guarantees placement.
SimpliSafe vs ADT: 3-year cost of ownership
Monthly price alone hides the real gap. Because ADT Pro Install usually spans 36 months, comparing SimpliSafe vs ADT over three years shows the true cost. Here is a representative example using entry-level equipment and professional monitoring:
| Cost over 3 years | SimpliSafe | ADT |
|---|---|---|
| Monitoring (36 months) | $22.99 × 36 = $827.64 | $24.99 × 36 = $899.64 |
| Starter equipment | ~$250 (often less on promo) | ~$349 |
| Installation | $0 (DIY) | $100–$200 |
| Approximate 3-year total | ~$1,078 | ~$1,349–$1,449 |
Over three years, SimpliSafe typically runs a few hundred dollars cheaper — and even more when its promotions cut equipment prices. ADT’s higher total buys professional installation, a longer guarantee, and its established monitoring network. That trade-off is the heart of SimpliSafe vs ADT.
SimpliSafe vs ADT pros and cons
