The short version, stated honestly: Ring is a DIY camera and doorbell brand with one of the deepest owner-review histories in this entire category. ADT is primarily a professionally installed, monitored alarm company whose retail Amazon presence — the ADT Blu line — is new and carries only a few dozen verified ratings per product. Comparing star ratings between the two is comparing a mature, high-volume Amazon retail brand against a company whose real business largely happens outside Amazon entirely.

Note: this compares Ring’s flagship doorbell against one ADT Blu retail product — ADT’s traditional professionally installed alarm and monitoring service is a separate, larger purchase this page does not have comparable Amazon review data for.
Where the Real Differences Are
Business model. Ring sells hardware direct-to-consumer with optional cloud subscriptions, no professional installer required. ADT’s traditional model is professional installation plus a monitored alarm contract — its retail camera and doorbell products are a newer, smaller part of that business.
Review evidence. Ring’s flagship devices carry tens of thousands of verified Amazon ratings. ADT’s retail products carry a few dozen each — nowhere near enough to draw a confident conclusion, and this page has no comparable review data at all for ADT’s core professionally installed service.
What you are actually buying. A Ring device is a camera or doorbell, full stop, with cloud recording as an optional add-on. ADT’s core value proposition is the monitoring relationship and emergency dispatch infrastructure behind the hardware, which a camera-review comparison like this one cannot fully capture.
Contract and cost structure. Ring’s subscriptions are month-to-month with no long-term commitment. ADT’s traditional monitored service has historically involved contracts, a frequently cited difference between the two kinds of companies.
Winner by Use Case
Best single camera or doorbell with a deep, trustworthy review base: Ring, by a wide margin on evidence.
Best for no long-term contract: Ring, on month-to-month plans.
Best if you specifically want a national monitored-alarm company with professional installation: ADT’s traditional service — outside what this Amazon-review-based comparison can properly evaluate.
Best low-commitment way to try the ADT name: ADT Blu, with the caveat that its review base is thin.

Verdict
Choose Ring for a well-evidenced, no-contract camera or doorbell you install yourself. Choose ADT specifically if a professionally installed, monitored alarm system with an established national dispatch relationship is what you actually want — a different category of product this comparison, built on Amazon review data, could not fully evaluate on ADT’s side.
