Side-by-Side Comparison
| Spec | Arlo Video Doorbell 2K (2nd Gen, AVD4001) | Blink Wired Doorbell 2K+ (BDM00500U, 2026) |
|---|---|---|
| Price | $79.99 | $39.99 |
| Release Year | 2023 | 2026 |
| Resolution (actual pixels) | 2K, 1944 x 1944 (3.8MP) with HDR, per Tom's Guide's spec table | Blink markets "2K+"; its own technical specifications page says "1920p" — a 1920 x 1920 square frame, the same pixel count as Ring's $99.99 "Retinal 2K", at up to 25fps |
| Aspect Ratio | 1:1 square (head-to-toe) | 1:1 (head-to-toe), per Blink's spec page |
| Field of View | 180° diagonal — the widest in this comparison | 140° horizontal, 173° diagonal |
| Power Source | Built-in non-removable rechargeable lithium-ion battery, or hardwired to existing doorbell wiring | Wired only — Blink states "Wired only (no batteries)" |
| Wiring / Transformer Requirement | Optional. Arlo does not publish a voltage range on its US product page; the doorbell is designed to install on standard existing chime wiring | 12-24V AC in the US (8-24V AC in EU/UK), or Blink's optional plug-in adapter. Critically, Blink's FAQ says the doorbell "does not ring your existing in-home mechanical chime" and that a bypass cable must be fitted at the chime, which disables it |
| Battery Life (claimed) | Arlo claims up to 6 months, explicitly "dependent on usage", and publishes no event count. Tom's Guide frames that as light use only | Not applicable — wired only |
| Wi-Fi Bands | 2.4GHz only, per Tom's Guide's specification table | 2.4GHz only (802.11 b/g/n); Blink asks for 2-6 Mbps upload depending on quality |
| Local Storage | None in the doorbell. Local backup exists only if you also buy an Arlo SmartHub or Base Station, sold separately | Only via a Sync Module 2 (USB drive) or Sync Module XR (microSD), both sold separately. Nothing is stored in the doorbell itself |
| Works Without a Subscription | Live view and basic motion notification. Tom's Guide: without a plan it is "stripped to a grossly basic live view and motion detector functionality" | Live view, motion alerts and two-way audio, plus local saving if you own a Sync Module |
| Behind the Paywall | 30-day cloud history, custom activity zones, person/package/vehicle/animal recognition, lock-screen clip previews and emergency response all require Arlo Secure — raised twice, to $7.99/mo for one camera and $12.99/mo for unlimited | Cloud clips, Person Detection, Vehicle Detection and the AI Smart Video Descriptions all need a Blink plan: Basic $3.99/mo, Basic AI $6.99/mo, Plus $11.99/mo, Plus AI $19.99/mo |
| Smart Home / HomeKit / Matter | Alexa, Google Home and Apple Home. Arlo's community manager confirmed Apple Home integration for 2nd-generation devices in March 2025 after a long delay. No Matter video | Alexa only. No Google Home, no Apple Home, no Matter |
| Indoor Chime | No on the 1-cam SKU. It can drive an existing wired chime, or Arlo sells Chime 2 separately | No — and it will not drive your existing mechanical chime. Blink's FAQ requires "a Blink Mini, Blink Chime, or compatible Alexa device (each sold separately)" for an in-home alert |
| Warranty | 12 months | 12 months |
| Colors | White | Black, White |

Pros & Cons
Arlo Video Doorbell 2K (2nd Gen, AVD4001)
Pros
- +180° diagonal is the widest view here, and it is a square 1:1 frame rather than a letterbox
- +The only doorbell in this set with a built-in 80dB siren you can trigger from the app
- +Works with Alexa, Google Home and Apple Home — the broadest ecosystem coverage of any non-Aqara model here
- +$79.99 for a battery-or-wired 2K doorbell undercuts Ring's equivalent by $20
Cons
- −The harshest subscription cliff in this comparison — no plan means no zones, no person alerts and no saved clips at all
- −Arlo Secure has been raised twice, from $2.99 to $4.99 to $7.99 a month for a single camera
- −The battery is not removable: recharging means taking the whole doorbell off the wall
- −Local storage requires an Arlo SmartHub or Base Station that is not in the box
- −2.4GHz only, and Arlo publishes no wired voltage range on its US page
Blink Wired Doorbell 2K+ (BDM00500U, 2026)
Pros
- +$39.99 buys the same 1920 x 1920 square sensor Ring charges $99.99 for in the Battery Doorbell 2K
- +No Sync Module required to work — it joins your Wi-Fi directly, unlike older Blink doorbells
- +Local saving to a Sync Module needs no subscription, which Arlo cannot match at any price
- +25fps is the highest frame rate among the budget models here
Cons
- −It cannot ring your existing mechanical chime — Blink's own FAQ says a bypass cable must be installed, which disables the chime permanently. You then have to buy a Blink Chime or an Echo
- −Local storage means buying a Sync Module 2 or XR separately, so the real entry price is well above $39.99
- −Person and Vehicle Detection are subscription features; with no plan it only tells you "motion"
- −Alexa-only, wired-only, 2.4GHz-only — the narrowest capability set in this comparison
- −"2K+" describes a 1920-pixel-wide frame, which is 1080p's width made square
