Lockin Veno Smart Locks: Palm Vein, Face and Solar

Best for
Solar fingerprint lock with a handle

Best for
Hands-free entry with solar power

The Lockin Veno Solar Face Smart Lock is the most futuristic lock in the range. Lockin describes an integrated perovskite solar panel feeding a 37Wh battery, with the panel said to capture light across 11 hours a day and keep charging in cloudy or rainy conditions as long as there is at least 1000 lux and the battery sits below 90 percent. A USB-C port covers emergencies, and no external panel is needed.

Entry is handled by 3D facial recognition that stores up to 50 users and unlocks in under a second. The listing gives the recognition distance as “23. inches”, which looks like a typo, so treat the exact range as unclear. Lockin says the sensor resists photo, video and mask spoofing. Built-in WiFi connects to the Lockin app for remote control, alerts and temporary passcodes, and Matter support brings in Alexa, Google Home and Apple Home. One oddity: the specification list mentions palm vein recognition, while the title and feature bullets only describe face unlock, and the included components list only names the exterior assembly. Confirm both before ordering.

This model suits households that want to walk up with full hands and never think about batteries. If you prefer a touch-based sensor, the solar fingerprint model later in this list is the closer match.

• 3D face recognition for up to 50 users
• Perovskite solar panel with 37Wh battery and USB-C backup
• Five unlock methods including voice and mechanical key
• Matter support for Alexa, Google Home and Apple Home

Biometric flexibility on a main entry

The Lockin Veno Smart Lock is the all-rounder of the family. It combines palm vein and fingerprint recognition, and Lockin quotes a 0.17-second unlock with 99 percent accuracy even with wet or worn hands. That makes it the lockin palm vein lock with the widest set of options: palm vein, fingerprint, PIN code, app, voice assistant and mechanical key, six methods in total.

Power comes from a rechargeable battery rated for up to seven months, with a USB-C emergency port. This is also the most rugged lock in the listings, carrying a BHMA Grade 2 rating and IP65 weather resistance. Built-in WiFi connects to major smart home systems without a hub, and the box includes the interior and exterior assemblies, an accessory kit, the rechargeable battery and a manual. If you are weighing it against a fingerprint door lock with a single sensor, the second biometric method is the main gain.

Choose the Veno if your main entry faces rough weather or if family members differ on which sensor works best for them. It gives way to the solar models only if recharging every few months bothers you.

Best for
Palm vein entry on secondary doors

The Lockin Veno Go keeps the same palm vein sensor and the same quoted 0.17-second unlock as the standard Veno, but drops the fingerprint reader. That leaves five unlock methods: palm vein, PIN code, app, voice assistant and mechanical key.

Battery life is the same up to seven months with USB-C emergency charging, and built-in WiFi still skips the hub. The difference is protection: the Veno Go is rated BHMA Grade 3 and IP53, a step below the Veno’s Grade 2 and IP65. The listing names only the exterior assembly under included components, so check what arrives in the box.

The lockin veno go makes sense for a garage entry, a back door, or a rental where palm vein alone is enough. For a primary door exposed to heavy rain, the full Veno is the stronger choice.

Best for
Solar palm vein with no subscription

Lockin provides only a listing title for the LockinSolar Powered Deadbolt, so our notes are short. The title describes it as the Veno Solar Palm Smart Lock: a solar powered deadbolt with palm vein keyless entry, five unlock methods, built-in WiFi and no subscription, working with Apple Home, Alexa and Google Home.

The listing does not specify the battery capacity, unlock speed, security grade, weather rating or which five methods are included. Based on the title alone, it sits between the Veno Go and the solar face model: palm vein recognition with solar power. If those missing details matter to you, the standard Veno and Veno Go publish far more.

Best for
Front doors needing a camera doorbell

The Lockin Veno Plus Smart Lock is a 4-in-1 device: keyless deadbolt, camera, doorbell and built-in WiFi gateway. It uses palm vein and fingerprint recognition with the same quoted 0.17-second unlock and 99 percent accuracy as the standard Veno.

The camera is a 2K ultra-wide unit with a 180-degree view, IR night vision and smart motion alerts. Video goes to 8GB of local storage with no monthly subscription. The listing names Alexa, Apple HomeKit, Google Assistant and SmartThings as supported controllers. It does not specify battery life or a security grade, so ask before buying if those matter. Readers comparing it with a smart door lock tied to a garage system will find the built-in camera is what sets the lockin veno plus camera model apart.

This suits families and rental hosts who want to see who is at the door without mounting a separate doorbell camera. If you already have a doorbell camera, the standard Veno gives you the same biometric options.

• 2K ultra-wide camera with 180-degree view and IR night vision
• Palm vein and fingerprint recognition
• 8GB local storage with no subscription
• Integrated doorbell and WiFi gateway

The Lockin Veno Solar Fingerprint Smart Lock shares the perovskite solar panel and 37Wh battery of the face model, and Lockin says it can charge from indoor or outdoor light. It adds a handle and uses a fingerprint reader rated at 97 percent or better recognition success, with a false rejection rate below 3 percent and a door-unlock time of 1.5 seconds or less.

The five unlock methods are fingerprint, PIN, app, voice via Alexa, Google or Siri, and mechanical key. Built-in WiFi and native Matter connect it to Apple Home, Alexa and Google Home, and the app handles access logs and temporary passcodes for guests or cleaners. A countdown auto-lock timer locks the door after a delay you choose. It is BHMA Grade 3 and IP53 rated, and the body is aluminum measuring 11.42 x 3.86 x 4.77 inches.

This is the lockin veno solar pick for anyone who wants solar power with a familiar touch sensor. It gives way to the standard Veno if you want Grade 2 security, and to the face model if you want hands-free entry.
