Reolink Argus 4 Pro vs eufy SoloCam S340
Which should you buy? Our verdict on both, pulled from our full The Best Outdoor Security Cameras: Wide Coverage Without the Monthly Trap comparison.
The Reolink Argus 4 Pro delivers the widest, sharpest coverage and the most honest ownership cost, recording locally with every smart feature unlocked at no monthly charge. The eufy SoloCam S340 runs it close for anyone who prefers an active pan-tilt view over a fixed panorama.
Reolink Argus 4 Pro
Buy itThe widest and sharpest no-subscription camera, provided you feed it enough storage and signal.
- Twin 4mm lenses produce a true 4K, 180-degree panorama with no blind-spot seam down the middle
- ColorX F1.0 sensor holds full color at night without a spotlight, and person/vehicle/animal detection plus microSD-to-512GB or Home Hub storage carry no monthly fee
- Panoramic 4K clips are large, so a high-capacity card or the separate Home Hub is close to mandatory for a useful history
- Even with dual-band Wi-Fi 6, the twin-lens stream leans on a strong signal and the 5000mAh battery drains faster in busy, always-triggering spots
eufy SoloCam S340
Buy itA dual-lens pan-tilt watcher that follows and zooms, with onboard storage and no fees.
- Pairs a 3K wide-angle lens with a 2K telephoto and 355-degree pan plus 60-degree tilt, so it tracks a subject and zooms in up to 8x
- Ships with 8GB of built-in local storage and on-device human/vehicle detection at no subscription cost, and the bundled solar panel keeps it self-charging
- Only 8GB of onboard storage without adding a HomeBase, so long or high-traffic histories overwrite quickly
- The pan-tilt motor and telephoto framing can lag behind fast movement, sometimes catching the tail end of an event rather than the start
