eufy Security S330 Dual Cam Wireless Video Doorbell | As New/Open Box
eufy Security S330
Dual Camera Video Doorbell
One camera looks ahead, one looks down at packages — no blind spots, no missed deliveries.
Open-box condition · Big savings · Same protection
HomeBase Required
This is an Add-on Unit and requires a HomeBase 2 or HomeBase 3 to operate. If you already have a eufy HomeBase, this doorbell will connect seamlessly. Don't have one yet? Check out our HomeBase listings. 🏠
What "Open Box · As New" actually means
This S330 is brand-new, unused open-box stock — it's been opened and checked, but never installed. Fully functional and ready to protect your front door for significantly less than a sealed retail unit. Same dual-camera tech, same eufy quality, just a smaller price tag.
Inspected
Opened and checked against original eufy spec.
Unused
Never installed or used — genuinely as-new.
Tested
Powered on and fully function-tested.
Repacked
Repackaged with all accessories for safe transit.
What to expect on arrival
Your S330 may arrive in its original box or in plain protective packaging — either way it's complete, with all essential accessories for installation included.
Cosmetically the unit is in as-new condition. It's open-box, not refurbished — so any marks, if present at all, are minor handling marks that won't affect function or looks once mounted. Functionally, it's a brand-new, unused unit. You're also covered by our free 30-day returns :)
Why the S330 is a game-changer 🚀
Two cameras really are better than one
Dual Camera Tech
One camera for faces, one for packages. See your visitors AND your deliveries — no blind spots.
Delivery Guard™
Get notified when packages arrive, auto-warn porch pirates, and set pickup reminders.
Crystal Clear 2K HDR
See every detail of your guests with 2K HDR on the main camera. No more squinting at blurry faces.
Dual Motion Detection
Radar + PIR sensors work together to reduce false alarms by up to 95%. No more alerts for leaves and shadows.
Two-Way Audio
Chat with visitors or give delivery instructions from anywhere. "Just leave it by the door, thanks!"
Motion-Activated Light
Built-in LED illuminates your porch at night — see packages clearly AND startle would-be thieves.
S330 vs E340 — what's the difference? 🤔
Both are dual-camera doorbells, but there's one key difference...
🎯 The Key Difference: Motion Detection
🔴 S330 (This One!)
PIR + Radar
When PIR detects movement, radar confirms it's real before alerting you.
Result: Up to 95% fewer false alerts. 🎉
🔵 E340 (Newer Model)
PIR Only
Still has AI person/package detection, but no radar double-check.
Trade-off: Colour night vision + detachable battery. 🌙
💡 What does PIR + Radar actually mean?
PIR = Detects heat-based movement (people, animals). It's good, but can trigger from sun/heat changes, passing cars, or shadows.
Radar = Scans for actual physical movement. When PIR triggers, radar confirms there's real movement before notifying you.
If you get annoyed by constant false alerts from leaves, shadows, or passing traffic — the S330's dual detection is why many people prefer it.
Tech specs for the nerds 🤓
Impressive dual-camera performance
S330 vs single-camera doorbells
Spoiler: two cameras win every time
What's in your package 📦
Everything you need to get started (HomeBase sold separately)
⚡ Installation Options
Install battery-powered for flexibility, or connect to your existing doorbell wires to extend battery life. Either way, setup takes about 5 minutes with a power drill and screwdriver. For best results, mount approximately 1.2 m (4 ft) above the ground. Easy.
