Alexa, Google Home, HomeKit, Matter — routines break at platform boundaries. Compatibility is verified per platform from documentation, not assumed from a logo on the box.
What works with no internet decides whether a device is robust or fragile. Fallbacks — physical keys, local recording, manual switches — are documented, never implied.
Microphone state, video storage location, account requirements and voice-history controls are evaluated alongside performance. Privacy is part of the verdict, not an appendix.
Mortise versus deadbolt, wired versus battery, renter versus owner — a device that does not fit the door or the lease does not fit the recommendation.
Ecosystem matrix: which platforms each device genuinely works with, Matter support for future-proofing, and whether a hub is required for full features.
Privacy review: physical mute controls, local versus cloud storage options, voice-history management, and the scope of app permissions requested at setup.
Physical fallbacks: keys, keypads, manual switches and local recording — what keeps working when the cloud, the app or the internet does not.
Installation reality: door prep measurements, wiring needs, power placement and landlord constraints, checked before the recommendation rather than after the purchase.
Outage behavior: which features pause when connectivity drops, stated plainly so readers know what they are depending on before they depend on it.
Maker track record: firmware support longevity and whether account requirements or subscriptions have changed after purchase in the past.
Hands-on lab-test score: Used exclusively for products the editorial team has physically tested and measured under a documented setup.
Research-based editorial score: Editorial judgment from published review consensus, specification analysis and third-party hands-on reports. It is not a lab result: it follows the article’s relative ranking and cited pros, cons and verdict, and products without an honest differentiating basis are marked Not scored.
Trust in a review starts before the first product appears — it starts with knowing how the reviewer works. This page is versioned and dated so that standard is checkable, not just claimed.
We practice evidence honesty throughout: sources reviewed are reported, manufacturer claims are labeled, and nothing implies product access or measurements that did not happen. The article receipt is where that honesty becomes visible.
