Eufy S330 Video Lock Review (2026)
The ultimate 3-in-1 security guard for your door.
The Eufy S330 solves a common problem: clutter. Instead of mounting a doorbell camera and a smart lock, Eufy combines them. It features a 2K HD camera, a fingerprint scanner, and a keypad. Best of all, it stores video locally, making it a star in our No-Subscription Smart Locks list.
✅ The Pros
- No Monthly Fees: Local storage on the included Chime.
- Fast Entry: Fingerprint reader recognizes you in 0.3s.
- Video Quality: 2K resolution is sharp and clear.
- Rechargeable: Uses a swappable battery pack (no AA batteries).
❌ The Cons
- Size: It is physically large on the door.
- No HomeKit: Does not support Apple Home.
- Camera Angle: Cannot see packages directly on the floor (since it's at lock height).
🤔 Verdict: Buy or Skip?
BUY IT IF: You want maximum security with zero ongoing costs. It's perfect if you haven't bought a Ring doorbell yet.
SKIP IT IF: You are an Apple HomeKit user or if you have a storm door (the storm door frame will block the camera view).
❔ Frequently Asked Questions
How long does the battery last?
The rechargeable battery lasts about 3-4 months per charge depending on how often the camera records motion.
Is the video storage really free?
Yes. The lock comes with a "Wi-Fi Bridge Chime" that has a microSD card slot. All your videos are stored inside your house, not in the cloud.
