Side-by-Side Comparison
| Spec | eufy Security Video Doorbell E340 (T8214) | Lorex 4K Wired Video Doorbell (B862AJD-E, 32GB) |
|---|---|---|
| Price | $149.99 | $186.99 |
| Release Year | 2023 | 2024 |
| 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" | 8MP, 2160 x 3840 — a true 4K-class pixel count, but rotated: 2160 across and 3840 tall |
| 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 | 9:16 vertical portrait — the tallest frame in this comparison. Best in the group for seeing a parcel on the mat, worst for seeing across a wide porch |
| Field of View | Not published by eufy in its E340 specification article, and absent from B&H's and eufy's own listings | 150° diagonal — the narrowest here, against 180° on the Arlo and Reolink |
| Power Source | Removable USB-C rechargeable battery, or hardwired. eufy requires the battery to stay installed even in wired mode | Hardwired only — no battery and no battery backup |
| 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" | 16-24VAC required, so an older 8-10VAC transformer will not run 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 | Dual-band 2.4/5GHz, 802.11 b/g/n/ac |
| 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 | 32GB microSD card pre-installed in the doorbell, upgradable to 256GB. No cloud subscription of any kind is offered or needed |
| Works Without a Subscription | Everything. Recording, playback, human detection, Delivery Guard package detection and face recognition all run locally with no plan | Everything: recording, playback and person, vehicle, animal and package detection are all local and free |
| Behind the Paywall | Nothing essential — eufy sells optional cloud backup only | Nothing — Lorex charges no monthly fee for this model |
| Smart Home / HomeKit / Matter | Alexa and Google Assistant. No Apple HomeKit, no Matter | Alexa and Google Assistant, through the older Lorex Classic app. 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 | Yes — a chime kit ships in the box along with mounting wedges and connecting wires |
| Warranty | 12 months | 12 months |
| Colors | Black | White, Black |

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
Lorex 4K Wired Video Doorbell (B862AJD-E, 32GB)
Pros
- +8MP is the highest pixel count in this comparison and it costs $63 less than Ring's 4K Pro — with no subscription at all
- +A 32GB card is already fitted, so it records out of the box with nothing else to buy
- +Package, person, vehicle and animal detection are free, where Ring and Arlo both charge monthly for the same list
- +Chime kit, wedges and wiring included, and dual-band Wi-Fi at a price where most rivals are 2.4GHz only
Cons
- −150° diagonal is the narrowest view here — the tall 9:16 frame trades width for height
- −16-24VAC hardwired only, with no battery option and no battery backup
- −The Lorex Classic app is dated next to Ring's or Google's, and there is no Apple Home or Matter support
- −Lorex's own product page has listed the doorbell as available only through direct contact with its sales team, so retail stock can be patchy
- −32GB fills quickly at 4K, so most buyers will want to swap the card immediately
