A smart door lock with camera is a keyless deadbolt with a video doorbell and intercom built in — see who’s there, talk to them, unlock from your phone. The best all-rounder right now: eufy FamiLock S3 Max at ~$330–$400 — 2K camera, palm-vein unlock, Matter support in one package.
What Is a Smart Door Lock With Camera?
Think of it as three gadgets merged into your front door. The lock itself replaces your key with a keypad, fingerprint reader, or — on the fancy models — a palm-vein scanner. The camera works like a video doorbell — motion wakes it, it records 2K or 1080p, your phone pings. The intercom lets you talk to the delivery driver from the office.
Why does the combo matter? A separate lock plus doorbell means two apps, two batteries, two mounts. A smart door lock with camera puts it all behind one app and one power system. The trade-off: one device doing two jobs drains its battery faster than either would alone.
3 Top Picks for 2026
Three models keep coming up whenever anyone asks which smart door lock with camera to buy — prices approximate, checked October 2026.
1. eufy FamiLock S3 Max — Best Overall
This is the one I’d buy with my own money. The headline is palm-vein unlocking: wave your hand and the door opens in ~0.6 seconds — no touch, so it works with dirty, sweaty, or gloved hands where fingerprint readers give up. Up to 50 palm profiles stored locally on the lock — not in a cloud — a genuine privacy win.
Camera side is equally serious: 2K HDR, 150° wide-angle, night vision, dual motion sensors, and human detection that ignores the neighbor’s cat. A 4-inch indoor screen lets kids and grandparents see who’s outside without a phone. Battery is a 15,000mAh rechargeable pack plus 4 AAA backups — eufy rates it around 5 months. Around $329.99 on sale (list $399.99), with Matter, Apple Home, Alexa, and Google Home supported — rare breadth for a smart door lock with camera. Check the official eufy FamiLock S3 Max page for the full spec sheet.
2. Lockly Vision Zeno — Best for Apple Households
If your home runs on Apple, this one deserves a long look. The Vision Zeno supports Apple Home Keys — your iPhone or Apple Watch becomes the key. Hold it near the lock and you’re in, no app-opening ritual. A 3D fingerprint sensor plus Lockly’s PIN Genie keypad — which shuffles digits every time so nobody reads your code from smudges — handles unlocking.
Video is 2K with two-way audio, roughly in line with the eufy. Pricing sits around $339–$429 depending on sales. As a smart door lock with camera for Apple homes, the fingerprint-plus-Home-Key combo is the smoothest daily experience here — though palm-vein fans will find the eufy more forgiving on rough hands.
3. myQ Secure View 3-in-1 — Best Budget
Not everyone needs palm scanning. The myQ Secure View 3-in-1 lands around $155–$235 (often near $199.99) with the essentials: 2K wide-angle night vision, biometric unlock, and a rechargeable battery myQ rates up to 6 months. It’s the sensible pick if you want the core experience — see, talk, unlock remotely — without paying for the bleeding edge.

What to Compare Before Buying
Unlock methods. Fingerprint is fast until your hands are wet or worn — then it’s infuriating. Palm-vein scanning sidesteps that entirely. Whatever you choose, make sure there’s a physical key backup. Electronics fail; a dead lock with no key is a locksmith bill.
Video and storage. 2K is the sweet spot — sharp enough to read a face, not so heavy it chokes your Wi-Fi. Then ask where footage goes: local storage (eufy’s HomeBase or built-in memory) means no monthly fee; cloud-only models nickel-and-dime you forever — often mattering more than the sticker price.
Battery reality. Video streaming is hungry — the biggest battery tax on any smart door lock with camera. The 10,000–15,000mAh packs in these locks last roughly 3–6 months depending on how busy your door is — a quiet side door sips power, a main entrance with fifty motion events a day does not. Check whether the battery is removable or the whole lock comes off the door to charge.
Ecosystem fit. A smart door lock with camera is only as smart as its integrations. Matter support — the standard our Matter support guide breaks down — means the lock talks to Apple Home, Google Home, and Alexa without vendor lock-in. All-in on Apple? Our Apple Home explainer covers what Home Keys needs. Google household? Pairing works much like our Google Home device walkthrough.
Detection smarts. The camera shouldn’t record 24/7 — a motion sensor wakes it only when someone approaches. That’s what makes multi-month battery life possible. If sensor tech is new to you, our plain-English sensor explainer covers how PIR motion and person detection work — same principles, different device.
The Honest Downsides
Let’s not pretend these are perfect. Battery anxiety is real — an all-in-one lock drains faster than a dumb deadbolt, and plenty of folks on Reddit’s home automation communities argue a separate lock and doorbell beats a smart door lock with camera for reliability. Fair point, honestly.
They’re hackable in theory, like everything with Wi-Fi. In practice, attacks target weak passwords and unpatched firmware, not Hollywood lock-picking. Strong unique password, two-factor on the app, prompt firmware updates — that closes nearly every real-world attack path.
Installation isn’t always 20 minutes. Standard doors: genuinely quick. Older doors with odd backsets may need an adapter or chisel. Measure twice.
FAQs
What is the best smart door lock with camera?
For most buyers in 2026: eufy FamiLock S3 Max (~$330–$400) — 2K camera, palm-vein unlock that works with dirty hands, 4-inch indoor screen, Matter support. Apple-first households should look at the Lockly Vision Zeno for Home Keys; budget buyers get the essentials from the myQ Secure View 3-in-1 (~$155–$235).
What is the best smart lock with camera for a main door?
A main door means heavy traffic, so prioritize battery capacity and detection smarts in your smart door lock with camera. The eufy FamiLock S3 Max’s 15,000mAh pack and human detection handle busy entrances best. Whatever you pick, confirm the IP weather rating (IP65 handles rain) and keep the physical backup key somewhere sensible.
What are the disadvantages of a smart door lock?
Four honest ones: battery dependence, higher upfront cost, Wi-Fi outages dropping you to keypad-only mode, and the small risk of software bugs. A physical key backup neutralizes the scariest scenario.
How hackable are smart door locks?
About as hackable as your email — the weak link is usually the password, not the lock. Reputable brands encrypt connections and store biometrics locally. Strong unique password, two-factor authentication, prompt firmware updates: practical risk drops to near zero.
Do I need a monthly subscription?
Not necessarily. Locks with local storage (built-in memory or a hub like eufy’s HomeBase) record with no fee. Cloud-only models may charge for video history beyond a few days. Check storage options before buying — subscriptions are the hidden cost that turns a $200 lock into a $400 lock over two years.
How long does the battery actually last?
Typically 3–6 months on 10,000–15,000mAh packs — every motion event and live view costs power, and cold shortens it further. Most apps warn you weeks ahead, so you’re rarely caught by surprise.
The Bottom Line
A smart door lock with camera earns its place when you’d otherwise buy a lock and a doorbell separately — one app, one install, one device to maintain. The eufy FamiLock S3 Max is the safest all-round bet, the Lockly Vision Zeno is the Apple-home pick, and the myQ Secure View proves you don’t need $400 for the core experience. Match the lock to your ecosystem, keep a physical key as backup, and you’ll wonder why you ever fumbled for keys in the rain.
Note: prices and specs shift often — verify against the manufacturer before buying. Install on doors meeting the lock’s thickness and backset requirements, keep firmware updated, and never rely solely on electronic access where a lockout would be a disaster.
