Lockin Veno Pro Review: Palm Vein, Camera, and Doorbell in One

A Smart Deadbolt That Is Also a 2K Doorbell Camera

The Lockin Veno Pro is a video smart deadbolt: a front door lock that pairs palm vein recognition, fingerprint reading, a backlit keypad, a mechanical key, and a full 2K doorbell camera in one exterior unit. Amazon lists it as a smart deadbolt lock with a 2K 180-degree security camera and video doorbell, AI local storage, palm vein and fingerprint keyless entry, built-in WiFi, and app control. That long product name is basically the honest summary: most devices on the market do one of these jobs, and this lock does nearly all of them without a hub, a bridge, or a monthly fee attached.

Specs and Build: IP65, Grade 2, and a Tempered Glass Face

The Veno Pro carries the features that matter for a permanent outdoor install. The exterior assembly is rated IP65, meaning dust-tight and resistant to water splashes in rain and snow, with a frosted tempered glass front panel that shrugs off fingerprints and stays clean. It is BHMA/ANSI Grade 2 certified and Lockin rates the hardware for a 10-year lifespan, with a working temperature range of -22 F to 158 F (-30 C to 70 C).

The exterior escutcheon measures about 7.2 by 3.2 by 1.4 inches (HWD), which makes it one of the bulkier smart locks on the market, but that volume holds the palm vein sensor, camera, keypad, doorbell, keyhole, and 32GB of onboard storage. The bottom edge hides an emergency USB-C charging port, a useful detail we will come back to.

Venokey Palm Vein Recognition: Raise Your Hand, Welcome Home

The headline feature is Venokey, Lockin's palm vein recognition system. A 60GHz radar wakes the lock when you approach, and an infrared sensor reads the pattern of veins beneath your skin rather than scanning the surface of your palm. Because the veins are inside your hand, a photo, a fingerprint mold, or a 3D printed replica cannot fool it, which is the privacy argument that fingerprints and face unlock cannot quite match.

In use it is genuinely fast. Lockin claims a 0.17 second unlock time with 99.9% accuracy, TUV Rheinland certified, and live testing felt that fast: raise your hand flat, the lock reads up to 50,000 vein data points, and the door opens. It also handles the hands that break other biometrics: wet hands, dry hands, dirty hands from gardening, aging hands with weak prints, long nails, or skin that is peeling or injured. During testing, a wet palm from rain unlocked on the first try, and so did an abraded thumb that would have confused a reader that only looks at the surface.

Multiple Unlock Paths: Fingerprint, PIN, App, and Physical Key

A palm vein lock still needs backup routes, and the Veno Pro has plenty. There is a fingerprint sensor on the front of the unit, a backlit capacitive keypad for 6 to 10 digit PINs (plus one-time PINs generated in the app and temporary PINs you can set a schedule for), app unlock over WiFi, and two physical keys included in the box.

The keyhole is cleverly hidden behind the doorbell button, so the front of the lock stays clean. Press the doorbell and you both ring the chime and expose the keyhole cover; pull it open and the mechanical key goes in when you need a guaranteed no-power fallback. Between the palm vein, fingerprint, PIN, app, and key, it is hard to be locked out, which is exactly the comfort level a smart lock should aim for.

LockinCam: A True 180-Degree 2K Doorbell Camera

Built into the same unit is a 2K camera calling itself LockinCam, and it is not a token sensor bolted on for show. The lens claims a true 180 by 180 by 180 degree field of view, so you see from head to toe at the door, not just a face at head height. In practice that means you can tell whether a delivery person actually set the parcel down at your feet, which is the angle most doorbell cams miss.

Low light is handled with infrared fill, switching to clear black-and-white image when the porch lights go off, and the two-way audio works like a proper video doorbell: talk to a visitor, or use the app's quick reply and auto reply messages when you are not home. The camera also records when the doorbell is pressed and when motion is detected, which ties into the AI layer below.

LockinAI and 32GB Local Storage: No Hub, No Subscription

Where most video doorbells push you into a paid plan for clip storage, the Veno Pro keeps everything local. It bundles 32GB of onboard storage, and Lockin's AI, called LockinAI, runs on the device itself using a 60GHz radar plus PIR sensors and an on-device processing chip. It detects people, vehicles, and packages, without uploading footage to third-party servers. Biometric templates and videos stay on the lock, and peer-to-peer transmission is used for remote viewing.

That matters twice over. First, there is no cloud fee: keep 32GB of event clips locally instead of paying per month for the camera to save a handful of clips. Second, privacy: the featherweight daily footprint we have come to expect from doorbell subscriptions is gone, replaced by local processing. Detection is also fast, with alerts landing in the app within seconds of a package appearing or being picked up, which makes it a practical porch-pirate deterrent.

The Lockin Smart App: Modes, Access, and Notifications

Setup runs through the Lockin Smart app, which is straightforward on both Android and iOS. The activity feed is the hub of daily life: doorbell ring, door open, door unlock, door lock, and unusual activity each generate a notification, and the lock works as a door sensor so you know the door was actually closed after someone came in.

Access management is flexible. You can create multiple users, and give each one multiple palm vein profiles, fingerprints, passwords, and even temporary or one-time codes. Visitors can get a code that only works tonight, seasonal help gets a schedule, and the administrator can revoke anything at any time.

There are also convenience modes that make the lock feel less like a gadget and more like a doorman:

• Auto-lock, configured from immediately after closing up to 180 seconds, so the door secures itself every time, and one-touch locking on the keypad when you want it sooner.
• Wrong-try protection with configurable lockouts after 5, 10, or 15 failed attempts, plus anti-peep PIN protection and anti-tamper alerts.
• Home, away, geofencing, and party modes that change notification and locking behavior based on where you are.
• Power profiles: optimal battery, balance, surveillance, optimal surveillance, and custom, so you can trade camera activity against battery life.
• A recorded welcome-home voice message and voice masking, plus vacation security mode that restricts the door to the administrator only.

Power: Three Months of Battery, USB-C Fallback, and an Optional Solar Panel

The Veno Pro runs on a removable rechargeable lithium-ion battery pack that Lockin rates for up to three months per charge, and the app warns you at 10% long before you need to worry. In real use that means most households charge roughly four times a year, and a second battery, sold separately, can be swapped in instantly so there is no downtime.

If the battery ever dies completely, the emergency USB-C port on the bottom edge lets you power the lock from a portable power bank with enough juice to unlock, and of course the hidden mechanical key still works. An optional 2.3-watt solar panel, sold separately and also IP65, plugs into the same port for trickle charging, so homes with a sunny entryway can stretch a charge considerably and skip most charging entirely.

Installation and Door Compatibility

Installation is designed for one person with one screwdriver in about 15 minutes: remove your old deadbolt, slot in the new latch, mount the exterior and interior escutcheons around your door, and connect the small ribbon cable between them. The manual's wiring diagram is clear, and the included quick start guide runs through each step. We had the old lock off and the Veno Pro set up in the app within about 20 minutes without calling for help.

Compatibility is the one thing to check before you buy. The lock fits wooden doors 1-3/8 to 2-1/8 inches thick (35 to 55 mm) with a 2-1/8 inch crossbore and a 1 inch latch hole, and it works with both 2-3/8 and 2-3/4 inch backsets. It is not compatible with storm doors, which block the camera, nor with mortise locks or round latch faceplate cutouts, so a quick measurement of your door saves a possible return.

Smart Home: Matter, Apple Home, Alexa, Google Home, and SmartThings

The Veno Pro speaks Matter over Thread, which makes it one of the more platform-neutral smart locks you can hang on a door. It works with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings when paired through a Matter-compatible hub, so you can say "Hey Siri, lock the front door" or fold the door into an evening routine that also dims the lights. Built-in WiFi handles the direct app control and push notifications without needing a proprietary bridge.

Who Should Buy the Lockin Veno Pro, and Who Should Pass

This is an easy recommendation for:

• Anyone who wants to replace two devices (a smart lock and a doorbell camera) with one unit that stores its recordings locally for free.
• Households where some members have hard-to-read fingerprints: aging parents, kids, gardeners, swimmers, or anyone whose hands are wet, dry, or worn. Venokey was visibly built for exactly these cases.
• People who want Matter smart home integration across Apple, Google, and Alexa without committing to a single ecosystem.
• Homes with package delivery issues, since person, vehicle, and package alerts with head-to-toe footage deter and document porch theft.

Skip it if you have a storm door or a mortise lock, if the bidirectional view feels like more than your entryway needs, or if you expect every video doorbell feature at a slim-line footprint; the Veno Pro is a big, dense unit and it does not hide it.

The Bottom Line: Our Pick As the Best Palm Vein Video Smart Lock

The Lockin Veno Pro earns the "best palm vein video smart lock" label in our testing because it wins on every axis a front door cares about: instant touchless unlock, a true 180-degree 2K camera, sharp on-device AI detection, and 32GB of local storage that never asks for a subscription. The generous battery life, USB-C emergency charging, and optional solar panel close the power gap that plagues other camera locks, and the Matter support keeps it welcome in any smart home.

If you want one device on your front door that locks it, watches it, answers it, and stores the evidence locally, the Lockin Veno Pro is the palm vein smart lock to beat.
