I tested the ANNKE Palm Vein Smart Door Lock with 2K Camera — a 5-in-1 keyless entry deadbolt with palm vein recognition, AI human detection, infrared night vision, two-way audio, and a 10,000mAh rechargeable battery. Here’s what it actually delivers, where it falls short, and who should buy it.
Smart locks with cameras are not new. What’s new is palm vein recognition making it into a deadbolt you can actually buy for $199.99. That’s the position ANNKE is in with this device, and it’s either a smart move or a very crowded space they’re entering late. I spent time with the ANNKE Palm Vein Smart Door Lock with 2K Camera to find out which.
Palm vein technology reads the unique vein patterns beneath your skin using infrared light. No physical contact required. The lock claims 99.9% recognition accuracy and a 0.6-second response time. Those numbers sound good on paper, and the video review I put together below walks through how it holds up in practice.
According to the National Institute of Standards and Technology’s biometric testing research, vein-pattern recognition systems consistently outperform fingerprint readers in rejection error rates, particularly for users whose skin condition, temperature, or dryness affects fingerprint readability. That’s one reason this category is growing.
This is not a roundup. This article is built around my video review of the ANNKE lock, with full specs, real buyer feedback, honest pros and cons, and a detailed FAQ section for anyone still deciding.

Review Summary
ANNKE Palm Vein Smart Door Lock with 2K Camera
At $129.99, this is the most affordable way to put palm vein biometrics on your front door, and ANNKE doesn’t obviously cut corners to get there. The recognition is reliable, the camera delivers genuine 2K clarity with two-way audio, and the 10,000mAh battery means you’ll charge it a few times a year rather than swapping AAA batteries monthly.
The app needs work. And people who want Apple HomeKit or Matter compatibility will need to look elsewhere. But for Alexa/Google households who want keyless entry that works for every member of the family regardless of fingerprint quality — this is a strong buy.
Best for: Families, rental hosts, small offices, anyone who has struggled with fingerprint locks.
Skip if: You need Apple HomeKit, you want color night vision, or you want a more polished app experience right now.
The Palm Vein Technology: Does It Actually Work?
This is the part most reviews gloss over. Palm vein scanning uses near-infrared light to map the unique vein patterns beneath your skin. The lock never touches you — you hold your palm a few centimeters away from the scanner, and the infrared picks up the subcutaneous structure.
Why is this better than fingerprints? A few reasons. Veins are internal, so they’re not affected by cuts, dry skin, dirt, or age-related ridge wear. For households with elderly members or young kids with shallow fingerprint ridges, this is actually a meaningful improvement over traditional biometric locks. The recognition in testing was consistent — once enrolled correctly, the hand wave just works.
The enrollment process took about 3 minutes per user. You scan the same palm four to five times, and the lock builds a local template from the averaged result. Biometric data stays on the device. ANNKE doesn’t send it to a server.
Note on accuracy claims: ANNKE states 99.9% accuracy. This aligns with published figures for infrared palm vein systems generally, but real-world accuracy depends on enrollment quality and consistent hand position. The 0.6-second response is accurate in testing — it’s noticeably faster than fingerprint locks most people are used to.
2K Camera and Video Features
The camera is not an afterthought. It sits at the top of the exterior unit, angled to cover the entry area, and the 2K resolution gives genuinely clear footage. Night vision uses infrared, which means color disappears in total darkness — the image goes monochrome — but the detail holds up well enough to identify faces at a normal door distance.
AI human detection fires push notifications when a person approaches, not just on any motion. In testing, the detection was accurate and quick. There were occasional false positives from strong shadows, but fewer than I expected from a lock at this price.
Two-way audio works well through the app. The microphone picks up clearly, and the speaker on the exterior unit is loud enough to be heard from several feet back. Latency was acceptable — not a video call, but not frustrating either.
Live view is accessible through the app at any time, not just on alerts. That’s standard for this category but worth confirming — it’s here.

FAQ
Does the ANNKE palm vein lock work in the dark?
Yes. The palm vein scanner uses near-infrared light to read beneath the skin, so it operates independently of visible light. You can use it in complete darkness without any issue. The camera also has infrared night vision, which gives clear black-and-white footage in low-light conditions.
Can palm vein recognition be fooled or spoofed?
It’s significantly harder to spoof than fingerprints. The infrared scanner reads the vein structure beneath the skin, which is a living, internal feature — not a surface one that can be lifted from a glass or copied with a silicone mold. ANNKE claims 99.9% accuracy and 0% false acceptance in their spec sheet. In real-world use, the main way recognition fails is inconsistent hand position during enrollment, not external spoofing attempts.
Does the ANNKE lock store biometric data in the cloud?
No. All palm vein data is stored locally on the lock itself. ANNKE does not transmit your biometric templates to any cloud server. This is consistent with how most current palm vein locks are designed, following growing industry preference for on-device biometric storage.
How long does the battery last?
ANNKE equips this lock with a detachable 10,000mAh rechargeable battery pack. Actual battery life depends heavily on how often the camera triggers and how frequently the lock is used. In average household use, expect somewhere between two and four months per charge. The battery is detachable, so you can charge it separately without removing the lock from the door.
What happens if the battery dies completely?
There are two fallback options: the two physical backup keys that come with the lock, and an emergency power input on the exterior unit that accepts a USB power bank. Hold the power bank against the port, supply enough charge to wake the lock, and use any electronic unlock method. It’s not as elegant as some competitors’ solutions, but it works.
Does it work with Apple HomeKit?
No. The ANNKE Palm Vein lock supports Amazon Alexa and Google Assistant, but not Apple HomeKit or the Matter smart home protocol. If HomeKit integration is important to you, the eufy FamiLock S3 is the main palm vein alternative with Matter support, though it costs considerably more.
How many people can enroll their palm?
Up to 50 palm vein profiles. That’s enough for a large household, a small rental property, or a small office with multiple staff members. You can also set up to 16 PIN codes with scheduling and temporary access options — useful for cleaners, contractors, or Airbnb guests.
Is the ANNKE palm vein lock difficult to install?
Not if you’re replacing an existing single-cylinder deadbolt. The full process typically takes 25–35 minutes with basic tools. The installation guide is illustrated and clear. The main thing to check first is door prep — standard US backset dimensions (2-3/8″ or 2-3/4″) fit without modification. Thicker doors, European-spec doors, or unusual bored hole dimensions may require extra hardware.
Does the 2K camera record continuously or only on motion?
Motion-triggered recording is the default. The camera activates when the AI human detection senses a person approaching. You can also access live view at any time through the app. Cloud storage is available as an option; local storage uses onboard memory. Continuous recording is not the standard mode for this type of battery-powered lock camera.
How does palm vein recognition compare to fingerprint locks?
Palm vein recognition is more reliable for people whose fingerprints scan poorly — elderly users, people with dry or calloused hands, young children, or anyone who works with their hands. Fingerprint scanners can fail on dirty, wet, or worn fingertips. Vein patterns are internal and consistent regardless of surface skin condition. The trade-off is that vein scanners need a slightly correct hand position to read reliably; they’re not quite as forgiving of random hand angles as a flat fingerprint sensor.
What is the warranty on the ANNKE palm vein lock?
ANNKE’s standard product warranty covers manufacturing defects. Check the ANNKE website or your purchase confirmation for current warranty terms, as these can vary by region and sales channel. ANNKE does provide customer support and has been responsive to hardware issues in reported experiences, though app-related support has received more mixed feedback from users.
Does the lock auto-lock after the door closes?
Yes. The auto-lock function detects when the door is closed and automatically throws the deadbolt. You can configure the auto-lock timing through the app. This is one of the genuinely useful smart features here — it removes the “did I lock the door?” anxiety without requiring any active step from users.
Is the ANNKE palm vein lock suitable for a rental property?
It works well for this use case. The temporary PIN code feature lets you generate time-limited codes for guests without adding them as permanent palm vein users. You can schedule access windows, delete codes remotely, and review the access log to see who entered and when. The remote unlock via app also means you can let a guest in if their code isn’t working without traveling to the property.
If you’re building a broader home security stack, this lock pairs naturally with a dedicated camera system. Our review of the best wired PoE security camera systems and the best NVR camera systems cover the recording side of a complete setup.
Palm vein locks are still a new enough category that you’re not choosing between dozens of proven options. The ANNKE lock occupies a real position: the most accessible entry point into the technology, with hardware quality that justifies the investment. The app will likely improve. The biometrics work now.
