Reolink Altas PT Ultra vs Eufy SoloCam S340 Security Camera

The Eufy SoloCam S340 is the safer pick for most shoppers. It has a far larger track record: 4.4 out of 5 from about 1,100 ratings, with owners praising clear day and night video, easy setup and reliable solar charging. The Reolink Altas PT Ultra wins on raw resolution (4K versus a 3K wide plus 2K telephoto pair), a bigger 20,000mAh battery and a 512GB microSD ceiling, but its 3.8 from 17 ratings is thin and owners report more setup friction. Pick the Reolink for maximum detail and local storage; pick the Eufy for proven reliability and dual-view zoom.

  • Choose the Reolink Altas PT Ultra if you want the sharpest single-camera image, a huge battery and up to 512GB of local microSD storage.
  • Choose the Eufy SoloCam S340 if you want a proven, well-reviewed dual-camera with a built-in solar panel and a wide-plus-zoom view in one frame.

What reviewers say

Reolink Altas PT Ultra

  • 3.8 / 517 ratings

Owners like the sharp 4K picture, the wide pan-and-tilt range and the freedom from subscription fees. Complaints center on the app, Wi-Fi pairing and battery drain under heavy use.

What people mention
  • Video qualityPraisedOwners say the 4K picture is sharp and color night vision is a real step up from black-and-white.
  • Battery lifeMixedThe 500-day rating holds in PIR mode, but heavy panning and constant recording drain it much faster.
  • App and setupCriticisedSeveral buyers find the Reolink app clunky and Wi-Fi pairing unreliable during installation.
  • Pan and tiltPraisedThe 355° pan and 90° tilt let one camera watch a whole yard or driveway.

Eufy SoloCam S340 Security Camera

  • 4.4 / 51,100 ratings

Rated 4.4 out of 5 from about 1,100 ratings, the S340 is liked for its clear video, solar charging and easy setup. Complaints center on motion detection, clip loading lag and uneven connectivity and reliability over time.

What people mention

  • Solar chargingPraisedOwners report the removable solar panel keeps the camera charged without running wires.
  • SetupPraisedInstallation and app setup are described as quick and straightforward.

Questions and answers

Which has better picture quality?
The Reolink Altas PT Ultra has the higher resolution at 4K 8MP, so it captures more detail in a single frame. The Eufy S340 pairs a 3K wide lens with a 2K telephoto, which gives a zoomed view in the same frame but lower peak sharpness.
Which is better for seeing far away?
The Eufy S340 has a dedicated telephoto lens with 8x zoom and night vision rated to about 40 ft. The Reolink relies on 10x digital zoom from one lens, which softens the image as you zoom in.
Which lasts longer on a charge?
Reolink rates the Altas PT Ultra at up to 500 days on its 20,000mAh battery in PIR trigger mode, and includes a 16W solar panel. Eufy does not publish a day figure but ships a removable solar panel that owners say keeps it charged.
Do either need a subscription?
No. Both store footage locally, the Reolink on a microSD card up to 512GB and the Eufy in built-in storage, so neither requires a monthly plan.
Is the Eufy worth stepping up to over the Reolink?
If reliability and owner feedback matter most, yes. The Eufy has about 1,100 ratings at 4.4 versus 17 at 3.8 for the Reolink, and its dual-camera view covers more angles. Step to the Reolink instead if you want 4K detail and expandable storage.
Which is easier to install?
The Eufy S340 is the easier install. It is wire-free, compact and Eufy claims a 7-minute setup, and owners back that up. The Reolink is heavier at 853g and needs its bracket and solar panel mounted.
