What Is the Major Difference Between Eufy S330 vs E340
- Night Vision Performance: S330 uses standard night vision and PIR/radar motion sensors — it gets the job done for basic nighttime visibility. E340’s dual camera + color night vision with two built-in lights gives you clearer, richer low-light footage, making it easier to identify faces, packages, and movements at night.
- Porch & Package Coverage: S330 captures faces well but can leave the doorstep lower down less clear. E340’s downward-angled secondary camera fills that gap — capturing packages and floor activity that often matter most in real life.
- Smart Alerts & Detection: S330 includes radar + PIR detection with human and general motion alerts. E340 builds on this with enhanced AI motion detection and package alerts, which helps you focus on what matters (people, parcels) with fewer false triggers.
- Storage & Local Use: S330 typically uses HomeBase storage or microSD expansion through a hub. E340 stores clips locally with built-in 8 GB and can be expanded or integrated into a broader Eufy security ecosystem.
