Side-by-Side Comparison
| Spec | eufy Security Video Doorbell E340 (T8214) | Arlo Video Doorbell 2K (2nd Gen, AVD4001) |
|---|---|---|
| Price | $149.99 | $79.99 |
| Release Year | 2023 | 2023 |
| Resolution (actual pixels) | Sources conflict: eufy's own E340 specification article gives main camera 2048 x 1536 and second camera 1600 x 1200 (which eufy labels "1080p" although it is 4:3); B&H's listing for the same SKU claims 2560 x 1920 / 4MP. eufy markets both lenses simply as "2K" | 2K, 1944 x 1944 (3.8MP) with HDR, per Tom's Guide's spec table |
| Aspect Ratio | 4:3 on both cameras. There is no single head-to-toe frame — the second, downward-facing camera is what covers the doorstep | 1:1 square (head-to-toe) |
| Field of View | Not published by eufy in its E340 specification article, and absent from B&H's and eufy's own listings | 180° diagonal — the widest in this comparison |
| Power Source | Removable USB-C rechargeable battery, or hardwired. eufy requires the battery to stay installed even in wired mode | Built-in non-removable rechargeable lithium-ion battery, or hardwired to existing doorbell wiring |
| Wiring / Transformer Requirement | Sources conflict: eufy's product page says "8 to 24V and >10VA", while eufy's own E340 specification support article says "Existing Doorbell Wiring (16-24V, 10VA) or 19V-0.6A DC Power Adapter" | Optional. Arlo does not publish a voltage range on its US product page; the doorbell is designed to install on standard existing chime wiring |
| Battery Life (claimed) | eufy publishes no month figure for the E340. Linkd Home's 30-day heavy-use test ended at 74% and projected roughly 78 days to shutdown | Arlo claims up to 6 months, explicitly "dependent on usage", and publishes no event count. Tom's Guide frames that as light use only |
| Wi-Fi Bands | 2.4GHz only (802.11 b/g/n), plus a 433MHz radio for eufy chimes | 2.4GHz only, per Tom's Guide's specification table |
| Local Storage | 8GB eMMC inside the doorbell with no card slot — around 90 days at 30 twenty-second clips a day. Expanding it means buying a HomeBase S280 or S380 separately | None in the doorbell. Local backup exists only if you also buy an Arlo SmartHub or Base Station, sold separately |
| Works Without a Subscription | Everything. Recording, playback, human detection, Delivery Guard package detection and face recognition all run locally with no plan | 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" |
| Behind the Paywall | Nothing essential — eufy sells optional cloud backup only | 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 |
| Smart Home / HomeKit / Matter | Alexa and Google Assistant. No Apple HomeKit, no 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 |
| Indoor Chime | Not on this SKU. It drives an existing mechanical chime, a eufy HomeBase, or a smart speaker; the chime bundle is a separate purchase | No on the 1-cam SKU. It can drive an existing wired chime, or Arlo sells Chime 2 separately |
| Warranty | 12 months | 12 months |
| Colors | Black | White |

Pros & Cons
eufy Security Video Doorbell E340 (T8214)
Pros
- +The second, downward camera is the only genuinely different answer to the parcel problem here — everyone else stretches one lens into a tall frame
- +8GB on the doorbell itself means no hub, no card and no monthly fee, unlike Blink and Arlo whose local storage needs a base station
- +Works battery or wired, and the battery pops out on USB-C instead of coming off the wall
- +Face recognition and package detection run on the device — the same features Ring charges $19.99/mo for
Cons
- −eufy's own two sources disagree on the wiring requirement (8-24V vs 16-24V) and on the sensor resolution, which is careless for a $150 device
- −2.4GHz Wi-Fi only, and Linkd Home measured 13.6 seconds average notification latency with thumbnails
- −No field-of-view figure is published anywhere, so you cannot compare its coverage on paper
- −No Apple HomeKit and no Matter, so Apple households are locked out
- −eufy's history of cloud-privacy incidents is a real consideration for a camera pointed at your front door
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
