Arlo Video Doorbell (2nd Gen)

Compiled by SmartHomeWorkflow Research · Arlo · Cameras & Doorbells · ~$49.99 (us.arlo.com listed the doorbell-only SKU (AVD4001-100NAS) at $49.99 on 2026-08-14, read from the storefront's structured product endpoint. ⚠ A DISCOUNTED figure: the same endpoint carries a compare-at price of $79.99 and the page renders 'Original price $79.99 / Sale price $49.99 / Save 38%'. The doorbell-plus-chime SKU (AVDK4001-100CNS) was $69.99 against a $99.99 compare-at. Never treated as a live price.)

⚠ Similar names, different products: Arlo's storefront sells this simply as 'Video Doorbell', which collides with the older Arlo Essential Video Doorbell and Arlo Essential Video Doorbell Wire-Free that Arlo's own support articles still cover. The product type field is what disambiguates it: '2nd Generation · Wired or Wireless Setup'. Two SKUs exist under the one name — AVD4001-100NAS is the doorbell alone, AVDK4001-100CNS adds a chime.

Compatibility

? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.

Protocols: WIFI^[2]

What it can do^[10]

Some of these may need a paid plan — see Subscription reality below.

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[3][6]

◐ Works without a subscription: Yes, but material features need a plan.

• Free: Live video feed, Motion-detection notifications
• Behind a plan: Video Cloud Storage, Interactive Notifications, Video Object Detection, 60-Day Video History, Smart Activity Zones, 24/7 Emergency Response (from $9.99/mo)
• 5-year cost if you add the plan: ~$599 at $9.99/mo — price verified 2026-08-14

Vendor account required: Inconclusive — we read the vendor's own setup material and it does not say either way. Treat it as unanswered rather than as a no.^[9]

Arlo's own FAQ on the product page: 'Is a subscription required for my Arlo Video Doorbell (2nd Generation) to work after the 1-month trial ends? No. A subscription is not required for your Video Doorbell to work after the 1-month trial period. Without a subscription, you will continue to receive notifications when motion is detected and be able to view your doorbell's live video feed. However, a subscription is required to maintain premium features...' ⚠ READ THAT AGAINST THE SPEC SHEET: Arlo lists 'Storage Type: Cloud' for this doorbell and no local storage of any kind. On the Ultra camera the same subscription wording still leaves a hub that can hold video; here there is no local fallback at all, so an unsubscribed doorbell notifies and streams but retains nothing. Same plan ladder as the rest of the range — $9.99 billed monthly or $7.99/mo billed annually for a single camera, $19.99 monthly or $17.99/mo annually for unlimited, higher unlimited tiers at $29.99 monthly and $24.99/mo annually. annualUSD is null because Arlo advertises a per-month-billed-annually rate and states no annual total; a yearly figure would be our arithmetic, not Arlo's price.

Maintenance reality^[2]

• Batteries: built-in rechargeable (wire-free setup) or existing doorbell wiring
• Works without the internet: No — the core function depends on the vendor's servers, so an outage takes it with them.^[3]
• Arlo sells one doorbell for both installations — the product type reads 'Wired or Wireless Setup' and the box carries both a USB charging cable and a wire extension kit, plus flat and angled mounting plates. Chime behaviour is stated as working with an 'existing traditional chime, or Arlo Chime V2'. Arlo gives a minimum home upload speed of 2 Mbps, which is the kind of requirement that decides whether this works on a weak connection. No battery-life figure is published for the wire-free mode on this page, so none is recorded.

Security updates^[9]

Arlo publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.

The catch

The headline is the price, and the price is a sale: $49.99 against Arlo's own $79.99 compare-at figure. Underneath it, the thing worth knowing is what 'no subscription required' means on a device Arlo lists as cloud-storage-only. Without a plan you get live view and motion alerts — you do not get a recording of what happened, and unlike Arlo's hub-based cameras there is no local storage to fall back on. The square 1944x1944 sensor is a genuine advantage for a doorbell, showing a full head-to-toe view of a visitor and packages on the step, and it is why the resolution number does not compare directly with 2K widescreen rivals.

Who it's for

Households that want a cheap, well-shaped view of the front door and are either content with alerts-plus-live-view or have already decided to pay for a plan. It is the better Arlo choice for an Apple Home household — it is the one Arlo product here that names Apple — and the worse one for a SmartThings household, which is the reverse of Arlo's own Ultra camera.

Arlo makes no statement of non-support for either, so both are recorded unknown.

Install effort is not characterised by the vendor; the page's four-step setup and the inclusion of both a wire extension kit and mounting plates were judged insufficient to grade it, since the wired path involves mains doorbell wiring and the wire-free path does not. — gap record — no primary source obtained, verified 2026-08-14
