Summary

An outdoor pan/tilt floodlight camera with a dual-lens system and local storage that needs no subscription. Check your frame rate expectations before you buy: 15 fps can blur fast-moving subjects, and the camera requires wired power.

Strengths

  • The 2000-lumen dual-panel floodlight fully illuminates a backyard or driveway, with adjustable angle and brightness.
  • The telephoto lens captures faces and license plates up to 50 feet away in color when the floodlight is active.
  • Local recording on microSD or HomeBase 3 requires no subscription.
  • Onboard AI detects humans, pets, and vehicles without a plan, and tracks subjects automatically.
  • WIRED’s reviewer used it for over a year at his back door without reporting hardware failure.
  • The camera pans 360 degrees and tilts 120 degrees, with configurable patrol positions.

Weaknesses

  • The 15 fps frame rate can make fast-moving subjects appear blurry.
  • The camera requires wired power, so you need an outdoor outlet or an electrician.
  • The 8x zoom combines optical and digital, so the digital portion is not like-for-like quality.
  • The floodlight color temperature is fixed at 4000K and not adjustable.
  • Cloud storage starts at $3–4/month if you want event history beyond local recording.
  • The onboard AI sometimes flags a large cat as a human.

Floodlight and video quality

The E340’s core feature is its dual-lens system: a 3K wide-angle lens paired with a 2K telephoto lens offering up to 8x zoom. WIRED’s reviewer found the telephoto captures faces and license plates up to 50 feet away in color when the floodlight is active. The floodlight itself consists of two adjustable panels producing up to 2000 lumens of warm 4000K light, with brightness controllable in the app. WIRED’s testing found the panels bright enough to fully illuminate a backyard or driveway.

The primary weakness is the 15 fps frame rate, which can make fast-moving subjects appear blurry. This is a notable trade-off compared to competitors like the Arlo Wired Floodlight (30 fps) or Google Nest Cam With Floodlight (30 fps). The 8x zoom figure combines optical and digital zoom; the digital portion is not a like-for-like quality equivalent to optical zoom. The floodlight color temperature is fixed at 4000K and not adjustable, unlike some competitors that offer 3000K–6500K adjustment.

Alerts, tracking and smart home

Onboard AI detection covers humans, pets, and vehicles without a subscription. WIRED’s testing found alerts swift and mostly accurate, though the system sometimes flags a large cat as a human. AI tracking automatically follows detected subjects and returns to a preferred position when they leave the frame. The camera supports configurable patrol positions, activity zones, and privacy zones. It works with Amazon Alexa and Google Home, and the floodlight supports light scheduling and intensity adjustment in the app. Two-way audio and a 95 dB siren are built in.

Storage and running costs

Local storage via microSD card up to 128 GB or Eufy HomeBase 3 (sold separately at $150) requires no subscription, and continuous recording is supported. Optional cloud storage starts at $3/month for a single camera with 30-day event history, or $4/month depending on the plan. WIRED’s July 2025 review reported the E340 at $142–150 on sale from a $220 reference price. WIRED’s June 2026 guide lists it at $150 on sale (32% off) from $220 MSRP, with Best Buy at $160 (27% off) and eufy direct at $220. The camera occasionally drops in price.

Is it worth it?

At $150 or below, the E340 is strong value for an outdoor floodlight camera: 2000-lumen adjustable floodlight, dual-lens 3K/2K system with 8x zoom, AI tracking, local recording with no subscription, and IP65 rating. The 15 fps frame rate is the main compromise. At $150–$180 it is still reasonable, especially if you prioritize floodlight brightness and local storage over frame rate. At $180–$220 it is fair; compare alternatives with higher frame rates. Above $220 (MSRP) it is weak value unless the specific feature set is uniquely required.
