Eufy SoloCam S340 Challenges PTZ Solar Standards

June 23, 2026 — The release of the eufy SoloCam S340 has shifted the conversation toward dual-lens solar surveillance. This review examines how the S340 stacks up against the standard Outdoor Solar Security Camera for homeowners needing reliable property coverage without wiring.

I’ve spent plenty of time testing these setups, and the reality is that most solar gear fails when the clouds roll in. According to iPhone in Canada, the eufy SoloCam S340 retails for $259.99 CAD and is designed as a set-it-and-forget-it solution. While that price point is squarely in the mid-range, the dual-lens system offers a different perspective than the single-lens Outdoor Solar Security Camera often used for residential driveways.

Between these two, I’d go with the standard Outdoor Solar Security Camera if you prioritize a wider pan-tilt-zoom range for a business or large office lot. The eufy model is better for those who want localized AI tracking on a porch. iPhone in Canada notes that the S340 is frequently on sale for as low as $189.99, making it a strong contender for homeowners on a strict budget. However, the Outdoor Solar Security Camera provides color night vision and two-way audio that feels more robust for active monitoring.

Expert tip: When mounting any solar unit, ensure the panel faces south at a 45-degree angle. Even a high-end PTZ motor will drain the battery in forty-eight hours if the panel is shaded by a gutter or tree limb for half the day.

If you're on a budget, the single-lens units are usually more efficient because they have fewer moving parts to power. Skip this if you already have power outlets under your eaves; hardwired will always be faster than solar-plus-WiFi.

Here’s what I’d actually buy: the Outdoor Solar Security Camera. It handles the basics of PTZ movement and cloud backup without the software bloat that sometimes slows down proprietary dual-lens systems.
