Side-by-Side Comparison
| Spec | eufy Security Video Doorbell E340 (T8214) | Blink Wired Doorbell 2K+ (BDM00500U, 2026) |
|---|---|---|
| Price | $149.99 | $39.99 |
| Release Year | 2023 | 2026 |
| 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" | 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 | 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 (head-to-toe), per Blink's spec page |
| Field of View | Not published by eufy in its E340 specification article, and absent from B&H's and eufy's own listings | 140° horizontal, 173° diagonal |
| Power Source | Removable USB-C rechargeable battery, or hardwired. eufy requires the battery to stay installed even in wired mode | Wired only — Blink states "Wired only (no batteries)" |
| 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" | 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) | 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 | Not applicable — wired only |
| Wi-Fi Bands | 2.4GHz only (802.11 b/g/n), plus a 433MHz radio for eufy chimes | 2.4GHz only (802.11 b/g/n); Blink asks for 2-6 Mbps upload depending on quality |
| 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 | 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 | Everything. Recording, playback, human detection, Delivery Guard package detection and face recognition all run locally with no plan | Live view, motion alerts and two-way audio, plus local saving if you own a Sync Module |
| Behind the Paywall | Nothing essential — eufy sells optional cloud backup only | 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 and Google Assistant. No Apple HomeKit, no Matter | Alexa only. No Google Home, no Apple Home, no Matter |
| 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 — 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 | Black | 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
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
