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.

Specifications
Chime
An 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
Siren
The 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 view
180 degrees with a complete head-to-toe image, as on the unbundled doorbell — the only field of view figure on this shelf
Power
Wire-free with a rechargeable battery, or hardwired to existing wiring for trickle charging — stated. The chime itself is wire-free over Wi-Fi
Subscription
Arlo 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
Detection
Person, package, pet and vehicle, with custom activity zones and privacy zones — the same four classes and two zone types as the unbundled model
Ratings
IP65 on the doorbell, stated. No rating is given for the chime, which is an indoor device
Resolution
2K, stated
Price
Fifty-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.

Arlo AVDK4001-100CNS Video Doorbell 2K (2nd Gen) with Arlo Chime 2
$56
Wire-free with a rechargeable battery, or hardwired to existing wiring for trickle charging — stated. The chime itself is wire-free over Wi-Fi
Arlo 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
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 that
Scrolling back in time and AI-powered or intelligent alerts require a compatible Ring Protect subscription, sold separately. Nothing states what works without one
Retinal 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
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 products
Arlo 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 survives
2K, stated. Two doorbells on this shelf claim 4K and three claim 2K
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 included
Scrolling back in time and intelligent alerts require a compatible Ring Protect subscription. Nothing states what works without one
NOT 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
What separates the models, in security devices
If price decides: Arlo AVD4001-100NAS Video Doorbell 2K (2nd Gen), wireless or wired, at $29.

2.5K 5MP · 166° wide · night vision · two-way audio with voice change · chime included
A 5 MP doorbell on a 166° lens with a chime in the box and a voice changer on the two-way audio. BOIFUN states human detection and Alexa compatibility through its own skill.
Best for: A house where the doorbell must be audible indoors without buying a separate chime.
2K 4MP · 150°×150°×180° 1:1 view · HDR · local person, vehicle, pet and parcel detection · dual-band
The second-generation battery doorbell: the same square head-to-toe frame with HDR added, and detection that Reolink states runs locally on the device rather than in a cloud service.
Best for: A bright doorway where a caller is backlit, and an owner who wants nothing leaving the house.
2K 4MP · 1:1 head-to-toe aspect · dual-band Wi-Fi · card to 256 GB · two charging methods
Reolink uses a square 1:1 sensor rather than a widescreen one, so the frame is as tall as it is wide and shows a caller head to toe with the step included. Local storage to 256 GB, with no subscription required.
Best for: A doorstep where the parcel matters as much as the caller.
