Cove vs ADT compared — both CSAA Five Diamond certified, but $19.99/month no-contract DIY vs $28–$60/month with a 2–3 year commitment. Our 2026 verdict.
Quick Answer
Choose Cove if you want CSAA Five Diamond certified professional monitoring without a long-term contract — starting at $19.99/month with DIY installation. Choose ADT if you need professional installation, the largest monitoring network in the US (200+ centers), or an insurance certificate your insurer will recognize without question.
Cove and ADT share something most buyers don't expect: both use CSAA Five Diamond certified monitoring — the highest certification in the industry. That means the core monitoring quality difference between them is smaller than the price and contract difference would suggest. Cove delivers that same certification from $19.99/month with no contract and a 30-minute DIY install. ADT Professional delivers it from $28–$60/month with a 2–3 year commitment and a licensed technician. If monitoring quality per dollar is your question, Cove wins clearly. If professional installation, insurer recognition, and the largest monitoring network in the US matter more than cost and flexibility, ADT is the right call. ADT Self Setup ($24.99/month, no contract, DIY) is a middle path worth knowing about.

Contract commitment — the defining difference
Cove Security
ADT (professional install)
This is the maximum Contract Risk Index spread on the site: Cove at 1/5, ADT Professional at 5/5. Both use CSAA Five Diamond certified monitoring — the price and exit risk gap is not driven by monitoring quality differences. ADT Self Setup ($24.99/mo, no contract) closes this gap significantly.

Is Cove's monitoring as good as ADT's?
At the certification level — yes. Both Cove and ADT professional plans use CSAA Five Diamond certified monitoring, which is the highest standard in the alarm industry. This certification requires strict redundancy, response time, and operational standards. The practical difference is scale: ADT has 200+ monitoring centers, meaning more redundancy if one center goes offline. For most homes, this redundancy difference is not operationally meaningful. For buyers who want the absolute maximum monitoring infrastructure, ADT's network size is a genuine advantage.
Can I get ADT without a long-term contract?
Yes — ADT Self Setup is a no-contract DIY option starting at $24.99/month. You install the equipment yourself, monitoring is month-to-month, and there's no early termination fee. This path removes ADT's biggest disadvantage (the 2–3 year commitment) while retaining ADT's monitoring network. The trade-off: ADT Self Setup equipment is a different hardware lineup from the professionally installed packages, and you lose the professional installation assessment.
What is Cove's Contract Risk Index vs ADT's?
Cove scores 1/5 — the lowest possible score, the same as SimpliSafe and Ring Alarm. ADT Professional plans score 5/5 — the highest possible score, reflecting the 2–3 year contract and ~75% early termination fee. This is the maximum spread in our 2026 Contract Risk Index. ADT Self Setup scores 1/5, the same as Cove. See the full methodology in our Contract Risk Index report.
Is Cove worth considering for a large home?
For homes under roughly 3,000 sq ft with a standard layout, Cove's DIY installation is practical and its CSAA Five Diamond monitoring provides full professional coverage. Above that threshold — or with multiple buildings, complex floor plans, or commercial-grade entry points — ADT's professional installation provides a real advantage. ADT's technician assesses sensor placement for your specific layout, which matters more as home size and complexity increase. See our best systems for large homes guide for a full breakdown.
Does Cove include cellular backup?
Yes — Cove includes AT&T LTE cellular backup on all plans at no extra cost. This means the alarm system can reach the monitoring center even if your internet or power is disrupted. ADT professional systems also include cellular backup. Both meet the standard required for reliable professional monitoring regardless of internet connectivity — cellular backup is non-negotiable for any serious monitoring setup.
