Lockin’s new V7 Max smart lock is what happens when a door lock, a security camera, and a sci-fi biometric scanner all get crammed into one sleek handle and then told to live forever on a beam of light. It is pitched as the kind of device you install once and then forget about charging, swapping batteries, or explaining to your guests which app they need just to get into your house.​

The hook is the power system, something Lockin calls AuraCharge — essentially an optical power link between the lock and a small transmitter that sits inside your home. Instead of AA cells or a rechargeable pack inside the door, the V7 Max has a panel on the interior side that drinks in energy from a dedicated transmitter plugged into a wall outlet within roughly four meters (around 13 feet), as long as it has line of sight. The company describes the light as “eye-safe,” and says the system can deliver continuous, efficient power regardless of room lighting or weather conditions, which is how it can keep the lock alive without you ever thinking about battery level. If that transmitter goes down — power cut, someone unplugs it, the dog knocks it off a table — the lock falls back on its internal lithium battery and keeps running for several hours, so you’re not suddenly locked out just because someone tripped over a cable.​

That alone would make it a quirky CES story, but the V7 Max is also a statement about what a smart lock in 2026 is supposed to look like. Instead of the usual rectangular slab with a keypad, the exterior side looks more like a minimalist, curved door handle, the kind of thing you’d expect on a high-end designer front door rather than a piece of security gear. The industrial design is credited to Hartmut Esslinger, the former Apple design chief behind the original Snow White design language, and it shows — the tech is there, but it doesn’t shout at you. On both the inside and outside, the lock uses built-in five-inch touchscreens, which is overkill compared to the tiny numeric grids most smart locks live with, but it lets Lockin layer in controls, video feeds, and prompts without turning the hardware into a button salad.​

The biometrics are where things really veer into future-door territory. Lockin leans heavily into vein recognition, offering both finger vein and palm vein scanning alongside 3D facial recognition as unlocking options. Vein biometrics scan the pattern of blood vessels under the skin using infrared, which makes them harder to copy than a fingerprint and less fussy about dirt, moisture, or aging skin — a pitch Lockin already makes with its Venokey palm vein tech on the Veno Pro lock, rated to unlock in about 0.17 seconds with 99.9 percent accuracy. It’s also more privacy-friendly than a face template, at least in theory, because your vein pattern is not something cameras casually capture out in the world. In day‑to‑day use, it boils down to this: you walk up, wave your palm or rest your hand where the lock tells you, and the door just opens, no keys, no phones, no passcodes.​​

On top of all that, the V7 Max doubles as a full-blown video doorbell. The lock integrates outer cameras and uses an AI layer that Lockin calls LockinAI to do things like recognizing deliveries at your door, logging visitors, and potentially monitoring kids or older family members for safety issues. The company even talks about generating automatic highlight reels of family moments happening at your doorstep — think a montage of first‑day‑of‑school goodbyes or relatives arriving for the holidays stitched together by software. It’s very much the smart home pitch of the moment: a single, camera‑equipped device doesn’t just record, it “understands” what you’re doing and tries to turn that into stories and alerts.​

There is, however, an immediate question that comes with any device that claims AI‑powered monitoring: where exactly is it looking, and how far does that gaze go? Lockin’s public descriptions talk about “outer cameras” but also mention features that sound like they would require an inward‑facing view, such as monitoring for safety inside the home, yet early briefings have not clearly spelled out how many cameras there are or exactly what they see. For privacy‑conscious buyers, that ambiguity matters, especially when the same product is running continuous biometrics at the main entry point to your home and potentially piping that data into an app or cloud service. The company does lean on certifications — vein tech in its ecosystem has been tested by TÜV Rheinland for accuracy and safety — but that still leaves open the practical questions about how video and biometric data are stored, encrypted, and shared with other devices or services.​

Under the hood, the V7 Max is very much built for the current smart home ecosystem. The lock supports the Matter protocol, meaning that, in theory, it can plug directly into Google Home, Apple Home, Amazon Alexa, and Samsung SmartThings without brand‑specific bridges. For a category that has historically been fragmented by hubs and proprietary apps, that matters: your door lock becomes just another device you can automate with routines, triggers, and scenes — lock when you arm the security system, unlock when your phone arrives in geofenced range, ping you if it opens at odd hours. It is also a mortise‑style lock, which is more common in certain regions and buildings and usually requires professional installation; Lockin plans to bundle or offer pro install because swapping a mortise lock is more involved than just replacing a deadbolt.​

The AuraCharge system itself sits in a small but fast‑moving wave of “wireless power at a distance” experiments. The Alfred DB2S lock, for instance, can be continuously charged via Wi‑Charge’s infrared laser transmitter, which beams power from a ceiling or wall unit up to 10 meters away to a receiver on the lock. Those systems share the same promise — never dealing with a dead battery again — but come with different trade‑offs around installation, cost, and that gut‑level reaction to the idea of invisible beams filling your hallway. Lockin pitches AuraCharge as a “fourth generation” approach, claiming high efficiency, TÜV Rheinland and SGS safety certifications, and reliability across a variety of layouts and weather conditions, which is key if you’re trying to convince people that their front door should depend on light waves instead of lithium AAs.​

What Lockin is doing with vein biometrics also fits into a broader trend of pushing beyond fingerprints and PIN codes at the front door. The company already ships the Veno Pro, a deadbolt smart lock that combines palm vein recognition with a 2K video doorbell, app control, passcodes, and traditional key backup. The new Veno Pro Wireless that Lockin announced alongside the V7 Max takes that existing product and simply swaps its power source for the same optical AuraCharge system, giving buyers a more traditional form factor if the mortise handle look doesn’t fit their door or building. In other words, AuraCharge is not just a one‑off CES gimmick; Lockin clearly wants this to be a signature platform across its lineup.​

All of this tech ambition does raise a more grounded question: is this over‑engineering the humble front door? For many households, a good mechanical deadbolt and a simple keypad are still more than enough, and they come without the risk of firmware bugs, downtime, or suddenly discovering that a software update has changed how your family gets inside. Smart locks, in general, have had to win people over on reliability and security, and while wireless optical power solves the “my lock is dead” problem, it introduces the new concept of a small, line‑of‑sight transmitter as a single point of failure in your security chain. Even with a few hours of battery fallback, it is still another component that has to be placed correctly, kept plugged in, and not blocked by furniture or clutter.​

Then there is the question of cost and positioning. Lockin has not yet announced pricing for the V7 Max, only saying that preorders will open this month with shipping expected early in the year, which practically guarantees it will land in the premium tier of smart locks. Mortise‑style locks with integrated video, biometrics, and pro installation tend to run significantly higher than standard deadbolts, and adding cutting‑edge wireless power hardware and CES “Best of Innovation” status rarely leads to a budget‑friendly sticker. For tech‑forward homeowners and early adopters, that might be part of the appeal — this is one of those products that announces itself as much to you as to anyone standing on your doorstep.​

Still, there is a real problem being solved here, beyond the flash. Dead batteries are one of the most common and annoying friction points with smart locks; they can turn a smart home into an unexpectedly dumb one at exactly the wrong moment. By making the lock effectively self‑tending — as long as the transmitter is in place — Lockin is gunning for the kind of appliance‑like reliability people expect from light switches or thermostats, not from gadgets they constantly have to babysit. Combine that with a genuinely interesting approach to biometrics and a design that tries not to look like a piece of IT equipment glued to your door, and the V7 Max ends up feeling less like a CES stunt and more like a credible glimpse of where high‑end smart locks are heading.​

Of course, the usual caveats apply: real‑world reliability, software polish, Matter integration behaviour, and long‑term support will matter far more than the stage pitch once these locks are on actual doors. But if you step back and look at the broader pattern — optical power at a distance, vein biometrics, AI‑assisted doorbell cameras — the front door is quickly becoming one of the most technologically dense surfaces in the home, and Lockin’s V7 Max is very much a signpost of that shift.
