Eufy S330 vs S340 – Check Which One Is Best & Why?

Why Do I Recommend The Eufy S330? 

• The Eufy S330 features a 4K resolution sensor for sharper video quality and clearer detail in identifying faces or license plates, whereas the Eufy S340 uses a 3K resolution sensor with lower overall clarity.
• Eufy S330 comes with HomeBase 3 integration for expandable storage and advanced AI features like facial recognition, while the Eufy S340 relies on limited onboard storage without BionicMind recognition.
• It supports centralized storage expansion through a connected hard drive for long-term video retention, whereas the Eufy S340 is restricted to fixed internal storage.
• The Eufy S330 includes triple PIR motion sensors to detect movement beyond the camera’s immediate field of view for better coverage, while the Eufy S340 uses a single PIR sensor limited to the camera’s viewing angle.
• Eufy S330 works seamlessly in multi-camera setups through HomeBase 3 for scalable security systems, whereas the Eufy S340 functions mainly as a standalone device without hub-based coordination.
• It has a built-in solar panel on the camera body for a seamless power supply without extra cabling, while the Eufy S340 uses a separate cabled solar panel that requires additional mounting.
• The Eufy S330 stores all AI processing and data on the HomeBase for enhanced privacy and reduced camera-side processing load, whereas the Eufy S340 processes everything on-camera.
• Eufy S330 integrates more tightly with advanced security automations via the HomeBase ecosystem for smart routines and centralized alerts, while the Eufy S340 operates independently with fewer system-wide automation features.

Maybe the Eufy S340 price can make you comfortable because it’s a little bit cheaper than the Eufy S330. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
