Arlo AVDK4001-100CNS Video Doorbell 2K (2nd Gen) with Arlo Chime 2 review

The doorbell plus the thing a battery doorbell has no way of doing: making a noise inside the house.

The conclusion The same excellent twenty-eight dollar doorbell with the one thing a battery doorbell cannot do for itself: ring inside the house. Twenty-seven dollars buys a wire-free chime with selectable melodies, adjustable volume, no base station and an 80 decibel siren that doubles as a door alarm — the only decibel figure on this shelf. If the door is already wired to a working chime, buy the doorbell alone; if it is not, this is the complete product rather than a bundle.

What the maker puts in writing

  • The same 2K doorbell: 180-degree head-to-toe view, IP65, person/package/pet/vehicle detection, activity and privacy zones
  • “Arlo Chime 2 Smart Doorbell Accessory Included: Hear every doorbell ring and motion alert anywhere at home, deter intruders with the 80+ decibel siren or door alarm, and pick your melodies and volume, with wire-free Wi-Fi setup and no base station needed.”
  • Wire-free or hardwired for trickle charging
  • “Live streaming and basic alerts work without a subscription.”
  • Nine of ten bullets are the unbundled listing’s, word for word

A battery doorbell has no chime

Which is the whole reason this bundle exists.

Press the button on an unwired battery doorbell and one thing happens: a notification on a phone.

Fine when the phone is in a pocket. Useless when it is charging upstairs, on silent, or in a coat in the hall.

This shelf’s introduction puts this inside the power question: a wired doorbell can ring your existing chime, and a battery one cannot.

Twenty-seven dollars for a chime that plugs in anywhere and needs no base station is the cheapest fix on this shelf. Nobody else here bundles one.

Eighty decibels, twice over

As a chime, and as an alarm.

Eighty decibels is about a vacuum cleaner — it carries through a closed door, which is what a chime has to do.

And it can be triggered as a door alarm, so the doorbell’s motion detection gets a sounder: somebody on the step at two in the morning sets off eighty decibels indoors rather than a silent phone alert.

It is the only decibel figure anywhere on this shelf.

When not to buy it

If the door is already wired to a working chime.

A hardwired installation rings the existing bell for nothing, and this bundle becomes twenty-seven dollars for a second sounder — which some houses want and most do not.

An apartment, a rental, or any door with no cable has no chime and no way to make one.

Then this is not a bundle. It is the product.

One bullet of difference

Out of ten.

Nine are the plain listing’s, unchanged — the 2K, the 180 degrees, the IP65, the zones, the detection classes, the subscription line.

The chime bullet is the whole decision.

  • An 80+ dB siren in the chime, the only decibel figure here
  • Melodies and volume both selectable

  • No transformer voltage for the wired mode
  • 2K rather than 4K

Specifications

ChimeAn Arlo Chime 2 included: it rings every doorbell press and motion alert anywhere in the home, with selectable melodies and volume, wire-free Wi-Fi setup and NO base station needed — stated. This shelf's introduction compares compatibility with an existing transformer and chime; this is the answer for a door that has neither, because a battery doorbell on an unwired door has no chime at all and the phone is the only alert
SirenThe chime carries an 80+ decibel siren that also works as a door alarm, stated to deter intruders. It is the only decibel figure on this shelf, and it turns the chime into a second device: a doorbell accessory that can be triggered as an alarm
Field of view180 degrees with a complete head-to-toe image, as on the unbundled doorbell — the only field of view figure on this shelf
PowerWire-free with a rechargeable battery, or hardwired to existing wiring for trickle charging — stated. The chime itself is wire-free over Wi-Fi
SubscriptionArlo Secure gives 60-day history, AI detection and emergency response on a paid plan after a trial, and live streaming and basic alerts are stated to work without a subscription. The chime works regardless: it is paired to the doorbell, not to the plan
DetectionPerson, package, pet and vehicle, with custom activity zones and privacy zones — the same four classes and two zone types as the unbundled model
RatingsIP65 on the doorbell, stated. No rating is given for the chime, which is an indoor device
Resolution2K, stated
PriceFifty-six dollars against twenty-eight fifty for the doorbell alone — so the chime costs about twenty-seven dollars bundled. Nine of its ten bullets are the unbundled listing's, word for word

The questions we are asked

Do I need a chime at all?

If the doorbell is on battery and the door has no wiring, yes — or the only thing that happens when somebody presses it is a notification on a phone. That is fine when the phone is in a pocket and useless when it is charging upstairs, on silent, or in a coat in the hall. This shelf's introduction frames this as part of the power question: a wired doorbell can ring your existing chime and a battery one cannot. Twenty-seven dollars for a wire-free chime that plugs in anywhere is the cheapest fix on this shelf, and no other maker here bundles one.

What is the 80 dB siren for?

Two things, and the second is the interesting one. As a chime it is simply loud enough to be heard across a house — eighty decibels is about a vacuum cleaner, which carries through a closed door. As a door alarm it can be triggered deliberately, so the chime becomes a sounder for the doorbell's motion detection: somebody on the step at two in the morning sets off eighty decibels indoors rather than a silent phone alert. It is the only decibel figure anywhere on this shelf.

Is the bundle worth twenty-seven dollars?

Compared with buying the chime separately, almost certainly — accessory chimes are rarely cheaper alone. Compared with doing without, it depends on the door: a house with an existing wired chime and a hardwired installation gets the ring for nothing, and this bundle is then twenty-seven dollars for a second sounder. An apartment, a rental or a door with no cable has no chime and no way to make one, and then the bundle is not an upsell but the complete product. Nine of the ten bullets are identical to the plain listing, so the chime bullet is the whole decision.

Ring 53-102272 Wired Doorbell 2K, Retinal 2K, 6x zoom $40 Hardwired: connect right into the same electricity that powers your home, stated. This shelf's introduction makes this the second axis — a wired doorbell never needs charging and can ring your existing chime, a battery one goes on a door with no cable and needs taking down to charge. This is the cheapest way on this shelf to be on the wired side of thatScrolling back in time and AI-powered or intelligent alerts require a compatible Ring Protect subscription, sold separately. Nothing states what works without oneRetinal 2K with up to 6x Enhanced Zoom, stated. Three doorbells on this shelf are 2K and two are 4K; the 4K models cost a hundred and ten dollars more and add 10x zoom
Arlo AVD4001-100NAS Video Doorbell 2K (2nd Gen), wireless or wired $29 Wire-free with a rechargeable battery, OR hardwired to existing wiring for TRICKLE CHARGING and uninterrupted operation — stated. That hybrid is the best of both: the battery means it goes on a door with no cable, and the wiring means it never needs taking down. One other maker on this shelf does the same; Ring sells wired and battery as separate productsArlo Secure gives 60-day video history, AI detection and emergency response on a paid plan after a trial — AND STATES THAT LIVE STREAMING AND BASIC ALERTS WORK WITHOUT A SUBSCRIPTION. That sentence is the clearest commercial statement on this shelf: three doorbells here put history and intelligent alerts behind a plan without saying what survives2K, stated. Two doorbells on this shelf claim 4K and three claim 2K
Ring 53-033551 Battery Doorbell, Head-to-Toe video $100 A built-in battery charging through a USB-C port, with the CHARGING CABLE INCLUDED — stated. Detach the doorbell from the wall and connect the supplied cable. Including the cable is worth noting, since Ring's newer battery model states the cable is not includedScrolling back in time and intelligent alerts require a compatible Ring Protect subscription. Nothing states what works without oneNOT PUBLISHED. No megapixel figure, no 2K, no 4K, no pixel dimensions anywhere in the seven bullets. Every other doorbell on this shelf states 2K or 4K, and the maker's own Retinal 2K wired model costs forty dollars against ninety-nine here
