Eufy sells more door lock models than almost any other brand in this category — S330, E31, E330, C220, C33, C210, C30, and others, with genuinely different feature sets rather than just cosmetic variations. This guide maps the confusing lineup clearly and picks the right eufy lock for your specific situation.
The Eufy Lock Lineup, Grouped by What They Actually Are
Video Smart Locks (S330, E330): These combine a fingerprint deadbolt with a built-in 2K camera and video doorbell in one device — genuinely three products in one, not just a lock with a camera bolted on as an afterthought. The S330 is the flagship, with a chime included, 128GB expandable storage, and 10% longer battery life than the E330.
Matter/Apple-focused locks (E31, C34): Built specifically around deep smart home ecosystem integration — native Matter support connects to Apple Home, Google Home, Alexa, and SmartThings without app-switching. The E31 is the flagship of this tier with the fastest unlock time in eufy’s lineup.
Budget fingerprint locks (C220, C33, C210): No camera, no premium ecosystem integration — just reliable fingerprint and keypad entry at accessible prices. C220 and C33 both include fingerprint entry; C210 drops fingerprint for keypad-only at an even lower price point.
Full Lineup Comparison
| Model | Camera/Doorbell | Fingerprint | Matter/Apple Home | Battery | Best For |

| S330 | Yes — 2K + doorbell | Yes | No | 10,000mAh rechargeable, ~6 months | All-in-one front door security |
| E31 | No | Yes | Yes — native | 10,000mAh rechargeable, up to 14 months | Apple/Matter smart home households |
| C220 | No | Yes | No | 8 AA, ~8 months | Budget-conscious buyers |
Best Eufy Locks — Verified Picks
Flagship: eufy Video Smart Lock S330
The S330 packs a genuinely rare combination into one device: rapid fingerprint recognition, a 2K HD camera, and a full video doorbell — three separate purchases most households would otherwise make combined into a single unit with one app, one battery, and one mounting point. Five unlock methods (fingerprint, app, voice assistant, keypad, physical key) cover every household member’s preference, and the included chime with 128GB expandable storage rounds out the doorbell side of the equation.
BHMA certified and IP65 weatherproof, rated for operation from -22°F to 158°F, the S330 is built to handle genuinely harsh climates without functional compromise. The 10,000mAh battery lasts roughly 6 months, with a swappable design that lets you charge a spare rather than taking the whole unit down while it recharges. Advanced detection features — departure detection, loitering alerts, and auto-lock confirmation once the door is securely closed — add real practical value beyond the basic lock-and-camera combination.
Best for Apple/Matter Households: eufy Smart Lock E31
The E31 is eufy’s answer for households deep in the Apple ecosystem — native Matter support means it works directly with Apple Home, Google Home, Alexa, and SmartThings without juggling multiple apps, and independent comparisons consistently rank it as the fastest fingerprint lock in eufy’s entire lineup at under 0.3 seconds to unlock. The 10,000mAh rechargeable battery is rated for up to 14 months per charge — genuinely long for this category, and longer than the S330’s roughly 6-month rating, since the E31 skips the camera and doorbell functions that draw additional power.
For households that already have security cameras covered separately and specifically want the fastest, most ecosystem-integrated lock available, the E31 is the clear pick over the camera-equipped S330.
Best Budget Pick: eufy Smart Lock C220
The C220 proves eufy’s fingerprint technology doesn’t require a premium price tag — sub-1-second fingerprint unlock, self-learning AI that improves accuracy with every use, and six total unlock methods including Apple Watch and voice assistant commands, all at the most accessible price point in the lineup. Built-in Wi-Fi means no bridge or hub purchase required for remote app control.
The honest trade-off: the C220 is explicitly not compatible with Apple HomeKit, IFTTT, or Matter, and doesn’t work with eufy’s HomeBase or any Wi-Fi bridge — a real limitation if ecosystem integration matters to you. It’s also BHMA Grade 3 rather than the higher Grade 1 certification found on premium models. For buyers who just want reliable fingerprint entry without deep smart home ambitions, none of this matters much in daily use.
Which Eufy Lock Should You Buy?
| Your Situation | Best Pick |
|---|---|
| Want lock, camera, and doorbell in one device | S330 |
| Apple Home or Matter ecosystem household | E31 |
| Tightest budget, still want fingerprint entry | C220 |
| Want a handle-based combo with fingerprint knob | C33 |
| Simplest possible setup, keypad only, no fingerprint needed | C210 |
Frequently Asked Questions
What’s the difference between the eufy S330 and E330?
Both are 3-in-1 video smart locks combining fingerprint entry, a 2K camera, and a video doorbell. The S330 is the newer flagship, including a chime, supporting up to 128GB of expandable storage, and offering roughly 10% longer battery life than the E330.
Does the eufy E31 have a camera?
No — the E31 is a fingerprint-only smart lock without any built-in camera or doorbell function. For camera-integrated options, look at the S330 or E330 instead.
Which eufy lock has the best battery life?
The E31 leads at up to 14 months per charge, longer than the camera-equipped S330’s roughly 6 months, since the E31 doesn’t power a camera and doorbell continuously. The budget C220 runs on 8 AA batteries for approximately 8 months.
Does the eufy C220 work with Apple HomeKit?
No — the C220 is explicitly not compatible with Apple HomeKit, Matter, or IFTTT, and doesn’t work with eufy’s HomeBase hub. For Apple ecosystem integration, the E31 is the right choice instead.
Do eufy locks require a subscription?
No — core lock functionality, fingerprint entry, and app-based remote control all work without any subscription across the entire lineup. The S330 and E330’s camera and doorbell features similarly work on local storage without a required subscription.
Final Verdict
| Your Situation | Best Pick |
|---|---|
| All-in-one lock, camera, and doorbell | eufy Video Smart Lock S330 |
| Apple/Matter ecosystem, fastest unlock | eufy Smart Lock E31 |
| Budget-conscious, reliable fingerprint entry | eufy Smart Lock C220 |
The Bottom Line
For most households wanting the most complete front-door security in one purchase, the S330 delivers genuine 3-in-1 value that would otherwise mean separate lock, camera, and doorbell purchases. Apple and Matter-focused households should go straight to the E31 for its native ecosystem integration and class-leading battery life. And for buyers who just want dependable fingerprint entry without the premium price, the C220 delivers real value with only modest smart-home trade-offs.
