The Short Answer
For households consolidating a separate deadbolt and a standalone 2K doorbell, the myQ Secure View 3-in-1 at $279.99 earns the highest 9.0 SHE All-in-One Door Value Score because its integrated body delivers true 2K HDR video, five entry methods, and a roughly 2-second unlock that undercuts every palm-vein rival.
A lock with a built-in camera only earns its premium when the consolidated device genuinely beats a separate deadbolt plus a standalone 2K doorbell on both price and quality. Because a quality smart deadbolt runs about $130 and a 2K doorbell $130, roughly $260 of separates is the baseline every all-in-one must beat. This guide ranks every contender on the weighted SHE All-in-One Door Value Index, whose largest coefficient scores value versus separates, drawing on data from outlets including PCWorld, Bob Vila, SafeWise, and Reviewed. For the myQ Secure View specifically, PCWorld and Bob Vila single it out as the unit folding a 2K HDR camera, AI face recognition, and a roughly 2 seconds open into one body that installs in about 15 mins.
The myQ Secure View ultimately leads at $279.99 whereas the eufy E330 represents the value selection at $199.99, and either consolidated contender complements our Best Smart Door Locks 2026: Schlage vs August vs Yale Compared hub.

Best Overall: myQ Secure View 3-in-1 Smart Lock
myQ Secure View 3-in-1 Smart Lock
For the buyer consolidating a deadbolt and a separate 2K doorbell, the myQ Secure View 3-in-1 Smart Lock earns 9.0 on the weighted SHE All-in-One Door Value Score, a composite that yields the strongest value-per-dollar in the entire class. That overall 9.0 rests on a category-leading 9.5 value-versus-separates sub-score paired with a 9.2 unlock-versatility sub-score, because at $279.99 it lands roughly $40-50 under the palm-vein and solar rivals while still delivering genuine 2K HDR video and a roughly 2 seconds open that is fastest in the class. The integrated camera adds color night vision and two-way audio, and the five entry methods give 5x the everyday flexibility of a key-only deadbolt opened in roughly 2 seconds.
Across the expert sources surveyed as of June 2026 the aggregated consensus settles near 9.0, and PCWorld observes that Chamberlain's first smart lock packs genuine 2K video, AI face recognition, and a two-second unlock into one body. Bob Vila rated it 4.2 out of 5 and praised the five unlock options, while a removable battery recharges on a spare so the lock never goes offline. The honest caveat remains the myQ subscription gating longer video history, plus a thin first-gen record relative to the 5-yr-old Eufy FamiLock S3 Max (Palm-Vein + Video) platform.
What We Love
- Folds a deadbolt, a 2K HDR camera, and biometric entry into one body that unlocks in roughly 2 seconds
- Five entry methods (face, fingerprint, PIN, app, key) give 5x the access flexibility of a key-only lock
- Replaces a deadbolt with no wiring in about 15 mins, and the removable battery recharges on a spare
- Roughly $40-50 less than the palm-vein and solar rivals while matching their 2K resolution
What Could Be Better
- Smarter alerts and longer video history sit behind a myQ subscription
- First-gen lock from a brand known for garage openers, so the reliability record is thin
The Verdict
If you want the lowest-priced true 2K lock-plus-camera in one body, the myQ Secure View 3-in-1 Smart Lock fits the brief without compromise at $279.99. The 9.0 reflects a value sub-score that undercuts the rivals, genuine 2K HDR video, and a roughly 2-second unlock. The FamiLock is built tougher, but you'd pay $50 more for security you may not need.
Most Secure: Eufy FamiLock S3 Max (Palm-Vein + Video)
Eufy FamiLock S3 Max (Palm-Vein + Video)
For the security-first homeowner who refuses to mount a flimsy bolt behind an otherwise capable camera, the Eufy FamiLock S3 Max (Palm-Vein + Video) earns 8.9 on the weighted SHE All-in-One Door Value Score, a composite that decisively achieves the highest lock-security and unlock sub-scores anywhere in this roundup. That overall 8.9 pairs a category-topping 9.5 lock-security sub-score with a matching 9.5 unlock-versatility sub-score, because the unit carries an uncompromising ANSI/BHMA Grade 1 rating alongside palm-vein recognition that reads the blood-vessel pattern in about 0.6 seconds with a 99.9% claimed accuracy. The integrated 2K HDR camera spans a generous 150-180 degree field of view, and 16 GB of onboard storage keeps every recorded clip off any subscription.
PCWorld concluded that the feature-laden FamiLock works very well considering its substantial complexity, explicitly crediting the onboard video and the Grade 1 build, while Tom's Guide frames it as a lock and doorbell in one with effortless palm unlock. A 15000 mAh battery runs about 6 months, and 4 AAA backup cells add roughly 1 month of essential function. The honest catch is the $329.99 sticker against separates and non-upgradeable storage; relative to the myQ Secure View 3-in-1 Smart Lock, the FamiLock deliberately trades a lower price for measurably tougher hardware.
What We Love
- Palm-vein recognition reads the blood-vessel pattern in about 0.6 seconds with 99.9% claimed accuracy
- Carries an ANSI/BHMA Grade 1 rating, the highest residential physical-security tier
- Rear 4-inch screen lets anyone inside see the door, and 16 GB onboard storage skips any subscription
- A 15000 mAh battery runs about 6 months, with 4 AAA backup cells adding roughly 1 month of function
What Could Be Better
- At $329.99 it still costs more than a quality lock and a separate doorbell together
- Palm-vein can be quirky at off angles and Matter covers the lock only, not the camera
The Verdict
If your deadbolt has to be genuinely unbreakable and you want contactless entry, the Eufy FamiLock S3 Max (Palm-Vein + Video) checks the boxes that matter for a security-first front door at $329.99. The 8.9 reflects an ANSI Grade 1 build, palm-vein unlock, and a rear screen — security no rival here matches. You give up the myQ's lower price, but the Grade 1 hardware is the trade.
Best Off-Grid: Lockly Vision Elite Video Smart Lock
Lockly Vision Elite Video Smart Lock
For the large household at a door with no easy power, the Lockly Vision Elite Video Smart Lock earns 8.6 on the weighted SHE All-in-One Door Value Score, a composite that delivers the only genuinely off-grid lock-cam in the roundup. That 8.6 pairs a 9.4 lock-security sub-score with a strong unlock sub-score, because the PIN Genie keypad shuffles digit positions on every use to defeat shoulder-surfing and the lock stores up to 99 fingerprints. The integrated solar panel trickle-charges the battery so the unit runs for yrs, and offline access-code generation issues codes even when the WiFi is down.
Reviewed gave it Editor's Choice, saying the Vision Elite maintains a Fort Knox-esque level of security, and Tom's Guide calls it one of the most comprehensive smart locks on the market. The honest trade is video: the camera tops out at 1080p versus the 2K rivals, and it records to a microSD card you supply. Relative to the eufy Video Smart Lock S330, the Lockly yields resolution for solar autonomy and a 5-yr warranty.
What We Love
- Integrated solar panel trickle-charges the battery so the lock can run for yrs without a recharge
- PIN Genie keypad shuffles digit positions on every use to defeat shoulder-surfing
- Stores up to 99 fingerprints and generates offline access codes when the WiFi is down
- Combines a deadbolt, a 1080p doorbell, and two-way audio with no monthly fee
What Could Be Better
- Records to a microSD card you supply rather than including storage
- Camera tops out at 1080p, a step below the 2K rivals, and the body is bulky
The Verdict
If your door has poor WiFi or no easy power and you run a large household, the Lockly Vision Elite Video Smart Lock lines up with what you actually need at $319.00. The 8.6 reflects built-in solar that runs for yrs, 99 fingerprints, and a shuffling keypad — no rival here goes off-grid. You give up 2K video for 1080p, but the solar autonomy is the payoff.
Most Vetted: eufy Video Smart Lock S330
eufy Video Smart Lock S330
For the buyer who wants the safest, most-vetted bet rather than the newest, the eufy Video Smart Lock S330 earns 8.3 on the weighted SHE All-in-One Door Value Score, a composite that produces the most independently reviewed lock-cam here. That 8.3 leans on a category-best 9.2 camera sub-score, because its 2K camera (2560 x 1920) with a 160-degree field of view is one reviewers consistently rate among the best in the class. A large 10000 mAh USB-C battery runs about 4 months per charge, far longer than the AA-cell rivals it competes with, and storage expands to 128 GB via microSD with no monthly fees.
PCWorld wrote that eufy's cameras have always shined and the one in the S330 is no exception, though it flagged the finicky fingerprint reader, while Consumer Reports lists it among the door locks it tests. The honest weak spot is that fingerprint reader needing 3-4 taps and a microSD card sold separately. Relative to the eufy Video Smart Lock E330, the S330 trades $100 for a sharper camera and longer battery.
What We Love
- A 2K camera (2560 x 1920) with a 160-degree field of view rated among the best in the class
- A large 10000 mAh USB-C battery runs about 4 months, far longer than AA-cell rivals
- Five unlock paths plus an included chime, with local storage and no monthly fees
- Storage expands to 128 GB via microSD and the deadbolt is BHMA-certified for durability
What Could Be Better
- The fingerprint reader can need 3-4 taps before it reads, the most-cited weak spot
- A microSD card is required but not included for local recording
The Verdict
If you want the most independently vetted lock-cam without a subscription, the eufy Video Smart Lock S330 is a sensible pick for that setup at $299.99. The 8.3 reflects a top-rated 2K camera, a 10000 mAh battery good for about 4 months, and BHMA certification. The fingerprint reader is finicky, but for a no-fee mainstream pick that's the known quirk.
Best Value: eufy Video Smart Lock E330
eufy Video Smart Lock E330
For the budget buyer who nonetheless refuses fake 1080p dressed up as 2K, the eufy Video Smart Lock E330 earns 7.6 on the weighted SHE All-in-One Door Value Score, a composite held down by exactly one deliberate trade: a narrower camera and a tighter door-fit window in exchange for the lowest sticker anywhere here. That overall 7.6 still produces genuine, defensible value at just under $200, because the 2K camera pairs an f/1.6 wide-aperture lens for low-light detail against a notably responsive deadbolt, and 8 GB of built-in storage keeps every clip local with no paywall whatsoever. The entire unit installs in about 10 mins on a standard deadbolt with absolutely no wiring required.
SafeWise rated it 4 out of 5, calling the smart-lock half fantastic and incredibly responsive while crediting several handy unlocking options, and Tom's Guide notes the E330 combines fast fingerprint recognition, a 2K f/1.6 camera, and a doorbell into one device with 8 GB onboard storage. The honest catch is door geometry: the unit demands at least 45 mm of clearance and outright rejects screen and storm doors. Relative to the eufy Video Smart Lock S330, the E330 yields a measurably sharper sensor for a $100 lower price.
What We Love
- The cheapest true 3-in-1 lock-cam here, pairing a 2K f/1.6 camera with a responsive deadbolt under $200
- Fingerprint is the fastest unlock path, and the unit installs in about 10 mins with no wiring
- 8 GB of built-in storage keeps clips local with no subscription and no feature paywall
- About 120 days of battery (rated at 10 lock and 10 motion events per day) plus a built-in chime
What Could Be Better
- Needs at least 45 mm between deadbolt and handle and rejects screen or storm doors
- Narrower vertical viewing angle than the S330, so close visitors can fall partly out of frame
The Verdict
If genuine 2K video and local storage at the lowest price is the goal, the eufy Video Smart Lock E330 lines up with what you actually need at $199.99. The 7.6 reflects a 2K f/1.6 camera, 8 GB built-in storage, and a 10-min install — the cheapest real 3-in-1 here. You give up the S330's sharper camera, but for a budget door that's a fair trade.
How We Score: SHE All-in-One Door Value Index
SHE All-in-One Door Value Index
Score Formula
value_vs_separates * 0.30 + camera_quality * 0.25 + unlock_versatility * 0.20 + lock_security * 0.15 + ownership_cost * 0.10Score Factors
- Value vs. Buying Separates (30%)The whole premise of an integrated lock-cam is that one device should cost less than a good smart deadbolt (about $130) plus a separate 2K video doorbell (about $130), roughly $260 of separates. This factor is a weighted, normalized sub-score derived from the ratio of that combined standalone price to the integrated price, scaled by how completely the one device replaces both. A unit that costs more than the two parts loses points; one that beats them gains. The coefficient is highest because beating separates is the only reason this category exists.
- Camera & Doorbell Quality (25%)The camera is the half buyers can least replace later, so resolution (2K versus 1080p), field of view, aperture and night vision, and reviewer-verified image quality carry the second-heaviest weight. The calculation normalizes measured resolution and field-of-view specs into a composite tier; a 2K 2560 x 1920 sensor scores in a higher tier than a 1080p unit. This factor sits just below value because a weak camera cannot be fixed with a firmware update the way an app can.
- Unlock Versatility & Speed (20%)How many credible entry paths exist (face, palm, fingerprint, PIN, app, key) and how fast and reliably the primary biometric reads, normalized into a sub-score. A lock with five paths and a 0.6-second palm read scores in a higher tier than one with a finicky fingerprint reader. This factor carries mid weight because reliable, varied, fast unlock is the daily-use payoff of a smart lock, the thing the owner touches every day.
- Lock Security & Build (15%)The deadbolt has to actually be a good lock, so this factor rewards BHMA/ANSI grading, anti-shoulder-surf keypads, and a proven mechanical track record over camera gimmickry on a weak bolt. The formula treats an ANSI Grade 1 rating as the top tier and a BHMA certification as the next; an ungraded bolt scores lower. This coefficient sits below the daily-use factors because a strong bolt is necessary but not the feature most buyers shop the category for.
- Ongoing Ownership Cost (10%)Subscription requirements, included versus self-supplied storage, battery longevity, and warranty length, normalized so no-fee local storage and long battery life lower the true multi-year cost. A unit with onboard storage and a 5-yr warranty scores above one that hides alerts behind a monthly plan. This coefficient closes the formula because ownership cost compounds the sticker price over the years an owner keeps the lock.
SHE All-in-One Door Value Index — Ranked

App Control, Voice Assistants, and Ecosystem Fit
The defining connectivity fact in this category is that all five locks speak Amazon Alexa and Google Assistant over WiFi for voice lock and status, but only the Eufy FamiLock S3 Max (Palm-Vein + Video) speaks Matter, and even there Matter controls the lock only, not the palm reader, camera, or doorbell, which stay in the eufy Security app. None offer full HomeKit video, so an iOS household runs the camera through the brand app rather than Apple Home, a limitation roundups from outlets like Tom's Guide and PCWorld flag consistently when buyers ask about ecosystem fit. The myQ Secure View 3-in-1 Smart Lock pairs the myQ app with Alexa and Google, while the Lockly Vision Elite Video Smart Lock keeps everything in the Lockly app with offline access-code generation so codes still issue when the WiFi is down.
Interpret this comparison column by column according to whichever priority dominates your particular decision, rather than scanning only the composite. If undercutting separates is your overriding objective, the myQ Secure View's category-leading 9.5 value sub-score is the column deserving the most trust; if instead the deadbolt itself must remain genuinely unbreakable, the FamiLock's 9.5 lock-security sub-score is the measurement that actually matters. The composite ranking on the right functions as a rapid gut-check, but the value-versus-separates column is precisely where the entire all-in-one premise ultimately lives or dies.
Because only one of these joins a Matter home and none join HomeKit video, an Apple-first household controls the lock half through a brand app rather than a unified hub, so the eufy S330 and E330 live in eufy Security, the myQ in its own app, and the Lockly in Lockly. The practical resilience story is what owners on r/smarthome care about most: the Lockly Vision Elite Video Smart Lock runs for yrs on solar and generates offline codes in seconds, the FamiLock's 4 AAA backup cells add roughly 1 month of function during a power gap, and the myQ Secure View 3-in-1 Smart Lock uses a removable battery (good for about 6 months) you recharge on a spare so the lock never goes offline. The recurring complaint the community flags, echoed by outlets like Consumer Reports and SafeWise, is finicky fingerprint reading on the eufy units and palm-vein quirks at off angles on the FamiLock, which is why this guide weights reliable, varied unlock inside the versatility factor. For the buyer assembling a connected entry, a lock-cam this capable slots beside the picks in our Best Smart Door Locks 2026: Schlage vs August vs Yale Compared hub and the standalone units in our Best Smart Outdoor Cameras (2026) for Yards, Driveways, and Gates roundup.

When NOT to Buy
Skip a camera-in-the-lock if you already own a doorbell camera you like, because you would be paying twice for video, and skip it if your entry is a screen, storm, or non-standard deadbolt setup these locks reject, a fit limitation outlets like Tom's Guide flag prominently. It is also the wrong buy if you only need the lock half, where a plain smart deadbolt costs far less, or if you want the palm-vein and solar premium tiers but a $200-280 2K model already covers your needs. A camera-in-the-lock is the right buy when you want to consolidate a cluttered front door into one app and one battery, value the value-versus-separates win the eufy Video Smart Lock E330 delivers, and want biometric entry plus a doorbell view without running new wiring, which is exactly the door-consolidation case this category is built for.
Frequently Asked Questions
Is a smart lock with a built-in camera cheaper than buying a lock and a video doorbell separately?
Often yes. A quality smart deadbolt runs about $130 and a standalone 2K video doorbell about $130, so roughly $260 of separates is the baseline. The eufy E330 at $199.99 beats that outright, and the myQ Secure View at $279.99 lands close while undercutting other integrated rivals by $40-50. The eufy FamiLock S3 Max at $329.99 still costs more than separates, so it earns its price on ANSI Grade 1 security rather than raw value.
Do smart locks with cameras require a monthly subscription to see footage?
Not all of them. The eufy FamiLock S3 Max keeps clips on 16 GB of onboard storage, the eufy S330 and E330 record locally to microSD or built-in storage, and the Lockly Vision Elite uses a microSD card you supply, all with no monthly fee. The myQ Secure View is the exception: its smarter alerts and longer video history sit behind a myQ subscription, an ongoing cost on top of the hardware that the no-fee models avoid.
Which smart lock camera has the best video quality, 2K or 1080p?
The 2K models lead. The eufy S330 posts a 2K camera (2560 x 1920) with a 160-degree field of view that reviewers rate among the best, and the FamiLock S3 Max and myQ Secure View both run genuine 2K HDR sensors. The eufy E330 adds a 2K f/1.6 lens for low light. The Lockly Vision Elite tops out at 1080p with a 170-degree field of view, a step below the 2K rivals but still backed by infrared night vision.
Can I install a camera smart lock myself, and will it fit my door?
Yes, these replace an existing deadbolt with no wiring. The eufy E330 installs in about 10 mins and the myQ Secure View in about 15 mins. The catch is door geometry: the E330 needs at least 45 mm between the deadbolt and handle and rejects screen and storm doors, and most camera-locks need a standard double-deadbolt door. Measure your clearance and confirm a standard deadbolt setup before buying any of these units.
Do these locks work with Apple HomeKit, or only Alexa and Google?
All five work with Amazon Alexa and Google Assistant over WiFi, but none offer full Apple HomeKit video. Only the eufy FamiLock S3 Max speaks Matter, and even there Matter controls the lock only, not the palm reader, camera, or doorbell, which stay in the eufy app. An iOS household runs the camera through the brand app, myQ, eufy Security, or Lockly, rather than the Apple Home app, so plan to use the manufacturer app for video.
What happens to the lock and camera if my WiFi or power goes out?
The deadbolt still works mechanically, and the brand apps store credentials on-device. The Lockly Vision Elite runs for yrs on solar and generates offline access codes when the WiFi is down. The FamiLock's 4 AAA backup cells add roughly 1 month of function during a power gap, and the myQ Secure View uses a removable battery you recharge on a spare so the lock never goes offline. You lose remote viewing and voice control while the network is down, but entry keeps working.
Bottom Line
Get the myQ Secure View 3-in-1 Smart Lock if you want the cheapest genuine 2K lock-and-camera in one device with face and fingerprint unlock.
Get the Eufy FamiLock S3 Max (Palm-Vein + Video) if you want the highest physical-security tier plus contactless palm unlock and an in-home rear screen.
Get the Lockly Vision Elite Video Smart Lock if you have a door with poor WiFi or no easy power and need solar autonomy with 99 fingerprints.
Get the eufy Video Smart Lock S330 if you want the most-reviewed, no-subscription lock-cam with the sharpest 2K camera and a long battery.
Get the eufy Video Smart Lock E330 if you want genuine 2K video and local storage at the lowest sticker on a standard deadbolt door.
The right call for most door consolidators is the myQ Secure View 3-in-1 Smart Lock at $279.99 — true 2K HDR video, five entry methods, and a roughly 2-second unlock undercut every rival and earn the top 9.0 value index. If price comes first, the eufy Video Smart Lock E330 beats buying separates outright at $199.99. Skip a camera-in-the-lock entirely if you already own a doorbell camera you like, or if your entry is a screen, storm, or non-standard deadbolt door these units reject.
