Eufy S340 vs S3 Pro: Feature Comparison
Design and Build Quality
Both cameras feature durable weather-resistant construction suitable for year-round outdoor use. The SoloCam S340 is slightly larger because it houses two lenses and a rotating motor, while the S3 Pro has a cleaner, more compact design that blends easily into most homes. Both are easy to install without complicated wiring.
Video Quality
This is where the S3 Pro clearly leads. Its 4K Ultra HD resolution captures finer details, making faces, packages, and license plates easier to identify. The SoloCam S340 records excellent 3K footage, but its biggest strength is combining two cameras for wider coverage instead of maximizing resolution.
If image clarity is your highest priority, the S3 Pro is the better option.
Coverage
Coverage is the SoloCam S340’s biggest advantage. Its motorized camera rotates horizontally and vertically, covering nearly every angle around your property. It can also automatically follow moving people or vehicles.
The S3 Pro uses a fixed viewing angle. While its image quality is superior, you’ll need multiple cameras to monitor large areas effectively.
Zoom Performance
The SoloCam S340 uses a dual-camera system to provide up to 8× hybrid zoom while maintaining good image quality. This makes it useful for monitoring driveways, gates, or distant entrances.
The S3 Pro relies mainly on digital zoom. Although the higher 4K resolution helps preserve detail, it cannot match the flexible zoom system of the S340.
Night Vision
Night performance is one of the biggest improvements in the S3 Pro. Its MaxColor Vision technology produces bright, colorful nighttime footage even in very low light.
The SoloCam S340 also delivers color night vision but depends more on its spotlight in darker conditions. For users concerned about nighttime security, the S3 Pro provides more consistent results.
AI Detection
Both cameras recognize people, vehicles, and pets while reducing unnecessary alerts.
However, the S3 Pro adds radar-assisted detection alongside passive infrared sensors, improving motion accuracy and reducing false notifications caused by rain, shadows, or moving trees.
If reliable alerts are important, the S3 Pro has the advantage.
Battery and Solar Charging
Neither camera requires frequent charging.
The SoloCam S340 includes an integrated solar panel that keeps the battery topped up with daily sunlight.
The S3 Pro introduces SolarPlus 2.0, offering even more efficient charging and longer battery endurance during cloudy weather. Both cameras require very little maintenance once installed.
Storage and Smart Features
Both cameras store recordings locally without mandatory subscription fees.
The SoloCam S340 provides onboard storage suitable for most homeowners.
The S3 Pro works seamlessly with HomeBase 3, allowing expandable storage and advanced AI features such as facial recognition and cross-camera event management. This makes it a better choice for larger home security systems.
Smart Home Compatibility
Both cameras support Amazon Alexa and Google Assistant, allowing voice control and live viewing on compatible smart displays.
The Eufy Security app is user-friendly on both models, providing live streaming, event playback, customizable activity zones, and notification settings.
Eufy S340 vs S3 Pro: Which Should You Buy?
Choose the Eufy SoloCam S340 if you need maximum coverage with fewer cameras. Its rotating design, motion tracking, and dual-camera zoom make it an excellent choice for large yards, driveways, and open outdoor spaces.
Choose the EufyCam S3 Pro if image quality is your top priority. Its 4K resolution, exceptional night vision, advanced AI, and HomeBase 3 integration make it ideal for homeowners who want premium security performance.
Frequently Asked Questions
Is the Eufy S340 better than the S3 Pro?
It depends on your needs. The Eufy SoloCam S340 is better for covering large outdoor areas thanks to its 360° pan-and-tilt capability and motion tracking.

Which camera is better for large backyards?
The Eufy SoloCam S340 is the better option for large backyards and wide outdoor spaces. Its 360° pan-and-tilt function, dual-camera design, and automatic motion tracking allow it to monitor a much larger area than the fixed-view S3 Pro.
Final Verdict
The Eufy SoloCam S340 and EufyCam S3 Pro are both outstanding wireless security cameras, but they serve different purposes.
