Eufy S340 Solar Camera

Verdict

The Eufy S340 Solar Camera is best if you do not have existing wiring and want an easy wire-free install with a solar panel that keeps the battery topped up and the same sharp dual-lens 3K/2K imaging as the floodlight model. It provides strong AI detection, 360 degree tracking, and convenient solar power, but the light is dimmer and motion-activated only, and it cannot record continuously, focusing instead on motion-triggered clips.

Pros

  • Articulation range 1 review 5.0
    A 360 degree pan mechanism lets the camera scan from the house wall out across the street, maintaining coverage as people walk through the front yard or along the sidewalk.
  • Optical zoom performance 1 review 5.0
    The S340’s 3X optical telephoto lens adds useful detail on people, vehicles, and license plates at the far end of a typical driveway before digital zoom is needed.
  • Installation ease 2 reviews 4.8
    Installation is simple thanks to the wire-free design, typically requiring only mounting the bracket and panel, which makes it accessible for homeowners who want to avoid electrical work.
  • Video resolution & detail 3 reviews 4.7
    Dual-lens 3K wide and 2K tele footage offers detailed results suitable for ID, with digital zoom limited by crop at higher levels.
  • Power options (solar panel) 3 reviews 4.5
    Included solar panel keeps the battery topped up; around two hours of direct sun can fully recharge, with an extension cable available for better panel placement.
  • Local storage option convenience 2 reviews 4.5
    Supports local recording on internal storage or via HomeBase, letting you keep clips in-house without a subscription if desired.
  • App controls & settings 1 review 4.5
    Using the Eufy app, owners can adjust solar cam light behavior, motion sensitivity, AI detection targets, and privacy zones, tailoring notifications and recording to their driveway or yard.
  • Battery life 1 review 4.5
    When positioned for a few hours of daily sun, the S340’s battery can stay fully charged for weeks, even with a partially shaded panel, minimizing the need for manual recharging.
  • On-device processing (AI) 1 review 4.5
    AI processing can run locally on the camera or be offloaded to HomeBase 3, which improves classification of people, pets, and vehicles while keeping analysis inside the home.
  • PTZ (pan/tilt/zoom) control responsiveness 3 reviews 4.3
    PTZ follows subjects across a wide arc and returns to presets quickly, now also swinging through a full 360 degrees and moving between user-defined zones to aid review of motion clips.
  • Detection features 3 reviews 4.2
    On-device AI detects people and vehicles and improves further with HomeBase 3, and now also recognizes pets while infrared-assisted tracking and fine-tuned rules help cut false alerts.
  • Digital zoom clarity 1 review 4.0
    Digital zoom beyond the 3X optical range still produces legible license plates and recognizable faces at roughly 60–70 feet, though sharpness drops compared with the base 3K/2K view.
  • False alert filter effectiveness 1 review 4.0
    Person detection generally ignores background movement, but in Wi-Fi only mode it can occasionally tag yard lights or trash cans as people until privacy zones and HomeBase 3 tuning reduce those false alerts.
  • Field of view 1 review 3.5
  • Floodlight brightness 1 review 3.5
    The integrated light is bright enough to illuminate a driveway and deter intruders when motion is detected, but it is dimmer than wired floodlight cams and cannot be left on continuously.

Cons

  • Audio recording quality 1 review 3.0
  • Notification speed 1 review 3.0
    During testing, push notifications arrived a few seconds after someone crossed into the detection zone, providing timely awareness without feeling sluggish.
  • Frame rate 1 review 2.5
  • Recording start-time lag 1 review 2.0
  • Continuous recording capability 1 review 1.5
    As a battery powered solar cam, the S340 focuses on motion triggered clips and does not support full-time loop recording, trading continuous coverage for battery life.
