Cameras, doorbells, and sensors: what they can cover, and what they cannot.
Comparisons and buying guides.
Whether the bell still rings inside depends on the model: the battery doorbells keep a compatible existing chime, two wired models replace it and the cheapest bypasses it. All eight current US models compared on chime, Wi-Fi band, charging, upload and subscription, with a pick per kind of house.
What the gear does, and where it falls short.
A Ring camera films in short clips unless you pay for more. What the subscription keeps, what Snapshot Capture fills in, which cameras can take the 24/7 add-on and what it switches off, and how long each kind of footage is kept.
An offline Ring camera leaves a gap: no live view, no alert, no clip, and nothing uploaded later. The four ways to lose the connection, what an Alarm Pro, Power over Ethernet and a phone hotspot each change, and why local storage is not offline recording.
Ring's 30 feet (9 m) of motion range says nothing about whether you could recognize the person it recorded. Field of view per model, the distance where a face stops being identifiable, what changes after dark, and what shrinks all of it.
Someone is often home, deliveries arrive during the day, and a doorbell or camera that alerts on every passing car is a nuisance rather than protection. We look at video doorbells, indoor and outdoor cameras, smart locks, and sensors: what they can cover, and what they cannot.
Each guide rests on what can be checked: what a device records and for how long, how far it sees, what it needs from your Wi-Fi and power, what the subscription adds, and which platforms it talks to. Where a manufacturer publishes a number, we use that number and say where it came from.
Start with the buying guides if you are choosing, or with the explainers if you already own a device and want to know what it is doing.
