Lockin Veno Pro: Palm Vein Recognition Smart Lock

Wave your hand near the door and the deadbolt retracts in 0.17 seconds - no key, no phone, no fingerprint smudge. That contactless palm vein unlock is the headline trick of the Lockin Veno Pro, a full deadbolt replacement that also crams a 2K video doorbell camera, a fingerprint reader, and a PIN keypad into one exterior unit. Announced at CES 2025, it's among the first consumer locks to pair contactless biometrics with a full-body panoramic camera and built-in local AI storage. Is a lock that reads the veins under your skin overkill for a front door? Maybe. But the way it folds four gadgets into one is genuinely clever.

What Sets the Veno Pro Apart

The Veno Pro stands apart from standard smart locks because it bundles four functions that typically require separate hardware: a biometric keypad, a video doorbell camera, a security hub, and a smart lock. Everything runs locally through the built-in AI storage, so there is no monthly cloud subscription required for basic video logging and entry history. That is a real advantage at the $349.99 price point compared to cameras that charge $5-10 per month for cloud storage.

Palm vein recognition uses the Venokey system to scan over 50,000 invisible infrared vein patterns beneath the skin. The company claims a false acceptance rate below 0.00001%, which is several orders of magnitude stricter than consumer fingerprint sensors. TUV Rheinland, the German independent testing and certification body, has verified the biometric accuracy - a meaningful trust signal for a security product.

Specs That Matter

The Lockin Veno Pro packs a significant amount of hardware into its exterior unit:

Key Points

• Palm vein recognition: Venokey system, 50,000+ vein data points, 0.17s unlock, 99.9% accuracy
• Fingerprint reader: Capacitive sensor, secondary biometric option
• Camera: LockinCam 2K HDR, 180-degree x 180-degree panoramic full-body view
• AI detection: LockinAI 60GHz radar + PIR dual sensors (person, package, vehicle)
• Connectivity: Built-in Wi-Fi, Matter protocol
• Smart home platforms: Apple Home, Amazon Alexa, Google Home via Matter
• Additional unlock methods: PIN code, smartphone app, NFC card, physical key cylinder
• Storage: Built-in AI hub, on-device footage and entry log storage
• Certifications: TUV Rheinland (biometric), FCC, CE
• Optional accessory: Solar panel for continuous battery charging
• Price: $349.99 standard, $419.99 with solar panel

The interior mechanism is a standard deadbolt that installs in place of your existing hardware. The front unit replaces the exterior keyhole assembly with the full biometric and camera module.

Smart Connectivity and Voice Control

The Lockin Veno Pro connects via built-in Wi-Fi using the Matter protocol, which means no separate hub or bridge is needed. Matter enables native integration with Apple Home, Amazon Alexa, and Google Home without going through proprietary cloud services. In practice, setting up voice control through Alexa or Google took under ten minutes from initial pairing.

Once connected, the lock becomes part of your broader smart home automation. You can trigger routines when the door locks or unlocks - dimming lights when leaving for the day, for example - or set up auto-lock after a set time window. The LockinAI detection system sends push notifications to your smartphone when it identifies a person, package, or vehicle at the door, and it filters out motion from trees, cars passing the street, or animals to reduce false alerts.

The built-in two-way audio lets you speak with visitors through the Lockin app even when you are away from home. Night vision keeps the 2K camera image clear after dark, and the HDR mode handles high-contrast outdoor lighting like bright sun behind a shaded porch.

Unlock Methods

The Lockin Veno Pro offers six ways to enter your home:

• Palm vein recognition (contactless, 0.17s, primary method)
• Fingerprint (capacitive reader built into keypad)
• PIN code (numeric keypad, supports permanent and time-limited codes)
• Smartphone app (Wi-Fi remote unlock from anywhere)
• NFC card or sticker
• Physical key (standard cylinder as emergency backup)

The palm vein sensor works reliably across all hand conditions. Lockin tested recognition with wet hands, dirty hands, elderly skin, and children as young as three years old. Users who struggle with fingerprint sensors due to dry or cracked skin should find palm vein more consistent as it reads subcutaneous vein patterns rather than surface texture.

Where It Shines

The combination of camera, dual biometrics, and local storage makes the Veno Pro useful across several scenarios:

• Family access: Enroll each household member's palm vein so nobody needs a phone or physical key to enter.
• Delivery monitoring: The 180-degree camera captures full head-to-toe footage of couriers and sends an alert when a package is left.
• Short-term rentals: Create time-limited PIN codes for guests that expire automatically, with a complete entry log stored on the device.
• Remote locking: Check lock status and lock or unlock from anywhere via the Lockin app over Wi-Fi.

Setup and Installation

Installation replaces both the exterior keypad and the interior deadbolt, making this a full lock replacement rather than a retrofit clip-on. Standard door prep with a 60mm or 70mm backset is required. The Lockin app guides through motor calibration, palm vein enrollment for each user, and Wi-Fi pairing. Matter setup connects the lock to your chosen smart home platform during the initial configuration flow.

Palm vein enrollment takes about 30 seconds per person. The app walks through holding your palm over the sensor from several angles to build an accurate recognition template. Additional users can be added later without re-pairing the lock.

Who the Veno Pro Is For

Buy the Veno Pro if you want contactless biometric entry plus a video doorbell in one device, and you own the door outright. The palm vein recognition does what Lockin says it does, and the TUV Rheinland certification is independent proof of the accuracy numbers rather than a marketing badge. On-device storage with no monthly fee is the practical win here. Competing video doorbells often charge $5 to $10 a month just to hold onto your clips.

Skip it if you rent or can't modify the door. This isn't a retrofit that clips over your existing thumbturn the way a SwitchBot lock does. It swaps out the whole deadbolt assembly, so you'll likely need landlord sign-off and a 60mm or 70mm backset. At $349.99 it also costs more than a plain keypad lock, and the math only really works if you'd otherwise buy a separate doorbell camera and a biometric lock.

One honest limitation: palm vein is still young in consumer locks, and you're trusting a 1-year warranty on hardware that sits outdoors year-round. If contactless entry and local video matter to you more than a long warranty does, the Veno Pro earns its price.
