When my neighbor’s package was stolen from her porch last month—captured on doorbell camera but too late to prevent—I realized my basic keyed deadbolt was woefully inadequate for modern home security. After researching smart locks and doorbell cameras separately, I discovered the Lockin smart lock with integrated 2K 180° camera and palm vein recognition, combining three essential devices into one revolutionary system. Two months after installation, it’s transformed not just my security but my entire entry experience.
If you’re searching for a smart lock with camera doorbell that eliminates keys, provides touchless access, and records everything without monthly fees, this Lockin Veno Plus with palm vein smart lock technology deserves serious attention. After daily use securing my front door, here’s my honest assessment of whether this 3-in-1 smart deadbolt lives up to its game-changing promises.

What Makes the Lockin Smart Lock Different from Traditional Smart Locks?
Unlike basic smart locks requiring phones or fingerprint scanning, or separate doorbell cameras needing additional hubs, the Lockin smart lock integrates palm vein recognition, fingerprint scanning, 2K 180° video camera, and video doorbell into one cohesive system. According to smart home security research from Security.org, integrated camera-lock systems prevent the installation complexity and aesthetic mismatch of separate devices.
The Lockin Veno Plus smart lock addresses fundamental home security challenges: keyless convenience, visual verification before opening doors, local video storage without subscriptions, and touchless access that works when hands are full, wet, or dirty.
The Palm Vein Recognition Revolution
Traditional biometric locks use fingerprints—easily affected by moisture, cuts, or dirt. The palm vein smart lock technology scans internal vein patterns beneath your skin, providing:
When my Lockin smart lock arrived, I expected complicated installation requiring professional help. The reality surprised me—I completed installation in approximately 45 minutes using just a screwdriver. The package includes:
Exterior assembly with camera and biometric sensors
Interior assembly with battery and controls
Rechargeable lithium-ion battery
Deadbolt lock body and strike box
All necessary hardware and mounting screws
Detailed quick-start guide
The lock fits standard doors (thickness 1⅜”–2¹¹/₆₄”, crossbore 2⅛”, backset 2⅜” or 2¾”)—covering 95% of residential doors. I replaced my existing deadbolt with zero modifications to my door.
Setting Up Palm Vein and Fingerprint Access
The Lockin Smart App guided me through registering biometric profiles. For palm vein recognition, I:
Downloaded the Lockin Smart App (iOS/Android)
Connected the lock to my 2.4GHz WiFi network
Held my palm 6-8 inches from the camera
Slowly moved closer while the system scanned
The app captured my palm vein pattern in about 30 seconds per hand. I registered both palms plus my wife’s palms (4 total). Fingerprint registration took even less time—about 10 seconds per finger. The system stores up to 50 palm profiles and 100 fingerprints.
Two Months Later: Real-World Performance
After 60+ days of multiple daily entries, here’s the unfiltered reality:
What’s Exceeded Expectations:
Palm vein unlocking works flawlessly 95% of the time—even holding groceries
2K camera provides crystal-clear visitor footage day and night
8GB local storage means zero monthly fees (records 30+ days)
Battery life remains strong (still at 60% after 2 months)
Smart motion alerts distinguish between people, vehicles, and packages
What Required Adjustment:
Palm recognition sweet spot is 6-8″ away (too close or far reduces accuracy)
2.4GHz WiFi only (my 5GHz network didn’t work initially)
Slightly bulkier than traditional deadbolts (extends 1.5″ from door)
The touchless door lock convenience proved genuinely transformative. Arriving home with arms full of packages, I simply wave my palm—door unlocks instantly. No fumbling for phones, keys, or touching anything.
The 2K 180° Camera: Security Beyond Just Unlocking
The integrated LockinCam provides genuine security camera functionality rivaling standalone doorbell systems:
Camera Specifications:
2K resolution (significantly clearer than 1080p doorbell cameras)
True 180°×180°×180° panoramic view (eliminates 75% more blind spots than standard 150° cameras)
Head-to-toe coverage even when visitors stand close to door
IR night vision for clear footage in complete darkness
Two-way audio for conversing with visitors or delivery personnel
Smart motion detection with AI-powered alerts
8GB local storage (approximately 30 days of recordings)
According to smart doorbell comparison research from CNET, the 180° panoramic view captures 40% more area than Ring or Nest doorbells, reducing porch blind spots where package thieves operate.
I’ve reviewed dozens of recorded events—package deliveries, neighbor visits, even a curious raccoon—and the 2K clarity exceeds my previous standalone Ring doorbell. The wider angle means I see visitors’ entire bodies, not just torsos.
Six Ways to Unlock: Ultimate Flexibility
The Lockin smart lock provides six distinct access methods:
1. Palm Vein Recognition (Primary): Wave palm 6-8″ from camera—instant touchless access. My preferred method 80% of the time.
2. Fingerprint Scanning: Touch sensor for quick unlock. 100% accuracy rate for me—never failed once.
3. PIN Code Entry: Keypad on exterior allows code entry (supports anti-peep codes for privacy). Perfect for kids or temporary guests.
4. App Control: Unlock remotely via Lockin Smart App. Used when letting in contractors while away.
5. Voice Assistant: “Alexa, unlock front door” works with Alexa, Google Home, Apple Home, Samsung SmartThings (requires Matter over Thread hub).
6. Mechanical Key Backup: Hidden key slot beneath doorbell button provides traditional key access if battery dies.
This redundancy means you’ll never get locked out. Even if technology fails, mechanical backup works.
Privacy-First Local Storage: No Monthly Fees
Unlike Ring or Nest requiring cloud subscriptions ($4-10 monthly), the Lockin smart lock processes everything locally. All facial recognition, biometric data, and video recordings remain on-device with:
Triple-layer encryption protecting stored data
Local AI processing (no cloud transmission for recognition)
P2P secure transmission when viewing remotely
8GB onboard storage (expandable via microSD—check specific model)
Zero subscription fees ever
According to privacy research from Electronic Frontier Foundation, local processing dramatically reduces hacking risks compared to cloud-dependent systems transmitting biometric data externally.
Over two months, my 8GB storage has maintained approximately 30 days of motion-triggered recordings. When full, the oldest footage automatically deletes, maintaining continuous recording.
Who Should Buy This Lockin Smart Lock?
Based on two months securing my home, this fingerprint keyless entry door lock excels for:
Tech-Forward Homeowners If you embrace smart home technology and want cutting-edge palm vein recognition, this represents the current pinnacle of residential security.
Families with Multiple Members The system stores 50 palm profiles and 100 fingerprints—accommodating large families, frequent guests, or Airbnb hosts managing property access.
Anyone Tired of Keys If you’ve locked yourself out, lost keys, or juggle too many keyrings, the touchless door lock eliminates these frustrations permanently.
Privacy-Conscious Users No cloud subscriptions mean your biometric data and security footage remain under your control, not stored on corporate servers.
Package Theft Victims The integrated camera with smart alerts notifies you instantly when activity occurs, deterring porch pirates through visible security presence.
Premium Pricing At $300-400, the Lockin smart lock costs 3-5x more than basic smart locks. However, you’re replacing both smart lock ($150-200) AND video doorbell ($150-250), making the combined value reasonable.
WiFi Dependency for Remote Features While palm vein and fingerprint work without internet, remote app access, notifications, and voice control require stable 2.4GHz WiFi.
Door Compatibility Not suitable for doors with storm doors blocking camera view or uncommon dimensions. Measure carefully before purchasing.
Palm Recognition Learning Curve The first week, I occasionally needed 2-3 palm wave attempts. By week two, muscle memory developed and success rate exceeded 95%.
Bulkier Profile The integrated camera adds depth—the exterior assembly protrudes approximately 1.5″ from your door. Not ideal for tight hallway installations.
How the Lockin Smart Lock Compares to Alternatives
Lockin vs. Ring Video Doorbell + August Smart Lock
Buying separately:
Ring Video Doorbell Pro 2: $250
August Wi-Fi Smart Lock: $200
Total: $450 + installation complexity + two separate apps + Ring subscription ($4/month = $48/year)
Lockin advantages:
Single integrated system ($300-400)
No subscription fees
Palm vein recognition (Ring/August lack)
Unified app experience
Lockin vs. Eufy or TCL Competitors
Eufy FamiLock S3 Max and TCL D2 Pro offer similar palm vein + camera combinations. According to smart lock comparison reviews, Lockin leads in:
180° true panoramic camera (vs 150-160° competitors)
Faster 0.17s palm recognition
TÜV Rheinland certification
Better app interface reviews
However, Eufy offers slightly longer battery life (8-10 months vs 6-7 months).
Lockin vs. Traditional Deadbolt + Separate Doorbell
The rechargeable lithium-ion battery provides 6-7 months per charge based on typical use (10-15 unlocks daily). The Lockin Smart App displays battery percentage, warning you 2-3 weeks before depletion.
Charging Options:
Remove battery, charge via USB-C port (takes 3-4 hours)
Optional solar panel accessory (sold separately) for continuous outdoor charging
Emergency: If battery dies, connect power bank to exterior USB-C port, then unlock via PIN code
The emergency charging port is genius—you’ll never get locked out even with dead battery.
Maintenance and Long-Term Care
After two months, here’s my maintenance routine:
Monthly:
Clean camera lens with microfiber cloth
Wipe palm vein sensor and fingerprint reader
Check battery level in app
Quarterly:
Review stored video footage, delete unnecessary clips
Test all six access methods
Inspect exterior for weather damage
