In today's rapidly popular smart home era, electronic door locks have evolved from simple "door opening and closing tools" into the first line of defense for home security, and even smart assistants for family life. At CES 2026, Lockin officially launched its flagship product – the V7 Max True AI Smart Electronic Door Lock (Deep Space Gray). With "wireless charging," triple biometric recognition (palm vein, finger vein, 3D facial recognition), and a built-in LockinAI True AI intelligent system, it brings an unprecedented experience of security and convenience to Hong Kong families.
This article will delve into the core technologies, security features, AI application scenarios of the Lockin V7 Max, and explain why it is considered one of the most forward-thinking smart electronic door locks currently available in the Hong Kong market.
World's First "Wireless Charging" Smart Lock: Bid Farewell to Battery Anxiety
One of the biggest pain points of traditional smart locks is battery life and replacement. The Lockin V7 Max introduces the innovative AuraCharge wireless charging technology, which uses infrared light of specific wavelengths to provide long-distance wireless power from an indoor transmitter to the door lock, supporting an energy transmission distance of up to approximately 4 meters.
This means:
- No need for frequent battery replacement: In a normal home environment, the V7 Max can achieve a near "infinite battery life" user experience.
- Stable power supply, unaffected by weather: Even if the entryway is dimly lit or the weather is changeable, the indoor transmitter can still provide stable power to the door lock.
- Reduced maintenance costs: For residents in high-rise buildings, commercial buildings, or those who travel frequently, it significantly reduces the risk of being unable to open the door due to a dead battery.
For Hong Kong's living environment, it is particularly suitable for high-frequency use families, families with elderly or children, and users who want to "install and forget."
Triple Biometric Recognition: Safer and More Personal than Fingerprints
The Lockin V7 Max features a multi-eye 3D precision recognition solution, simultaneously supporting three biometric identification methods:
- Palm vein recognition
- Finger vein recognition
- 3D structured light facial recognition
1. Palm Vein Recognition: 0.17 Second Lightning-Fast Unlock
The V7 Max's palm vein recognition response time is only about 0.17 seconds, with a false acceptance rate of less than 0.001%. Its security protection is reportedly 15 times stronger than traditional fingerprint locks.
Palm vein technology verifies identity by scanning the internal vein distribution of the palm. Compared to surface fingerprints:
- It is less affected by sweat, grease, dryness, or abrasion.
- It is more suitable for the elderly and children with fainter fingerprints.
- It is extremely difficult to forge, greatly enhancing anti-theft capabilities.
Users simply need to bring their palm close to the door lock to complete unlocking in the blink of an eye, experiencing almost "contactless entry."
2. Finger Vein Recognition: A More Precise Alternative
If users prefer to unlock with their fingers, the V7 Max also offers a finger vein recognition option, which also verifies based on vein distribution, balancing speed and security, suitable for family members with different usage habits.
3. 3D Facial Recognition: Unlock Upon Approach
The V7 Max uses structured light 3D facial recognition technology, which compares facial contours through depth mapping, similar to Face ID on mobile phones, but optimized for door lock scenarios.
Features include:
- Supports different heights (including children and the elderly).
- Accurate recognition even in dim environments.
- Can be set to "automatic unlock upon approach" or "unlock after confirmation," balancing convenience and security.
The triple biometric recognition can record multiple sets of data simultaneously (up to 50 sets each for palm, finger, and face), sufficient for large families or multi-tenant scenarios. hktvmall+1
LockinAI True AI Intelligent System: From "Passive Recording" to "Active Protection"
The V7 Max is not just a "door that can be unlocked," but a home security system equipped with an edge AI brain. The built-in LockinAI intelligent system can understand voice, image, and video data, and provides over 10 core AI application scenarios.
1. AI Video Understanding and Event Indexing
The V7 Max features the LockinCam Sentinel Triple Camera System outdoors:
- Top: 4-megapixel, 16° wide-angle lens
- Bottom: 2-megapixel, 89° wide-angle lens
- Paired with a 24GHz millimeter-wave radar to sense movement in front of the door.
When the system detects abnormal lingering, loitering, or suspicious behavior, the dual cat-eye lenses will link up instantly to capture images and activate the advanced pre-recording function, automatically saving approximately 3 seconds of footage from before the event occurred, ensuring complete preservation of critical evidence.
Thanks to AI video understanding technology, the V7 Max can automatically identify people, objects, and behaviors in the footage (e.g., "delivery person dropped off a package," "someone is loitering at the door"), and generate concise event descriptions, allowing users to quickly search and review them in the App.
2. 10+ True AI Smart Scenarios
According to official data, LockinAI offers over 10 core scenarios, including but not limited to:
- Delivery Detection and Management: Automatically identifies delivery personnel, records package placement location and time.
- Anti-theft Warning: Issues alerts for prolonged loitering, camera obstruction, and other behaviors.
- Elderly/Child Anti-loss Alarm: Can send notifications to family members when specific members go out alone or are absent for a long time.
- Visitor Management: Records visitor entry and exit times, and can set temporary permissions.
- Leaving/Returning Home Mode Linkage: Coordinates with other smart home devices to automatically turn on lights, air conditioning, etc.
These features allow the V7 Max to evolve from "passive recording" to "active guardianship," particularly suitable for dual-income families, and families with elderly or young children.
Dual 5-inch Touchscreens: Indoor and Outdoor Interaction
Unlike typical smart locks that only have a small screen indoors, the Lockin V7 Max is equipped with dual 5-inch high-definition touchscreens (resolution 720×1280) on both the indoor and outdoor panels.
Outdoor Touchscreen Uses
- Enter passwords, view door lock status.
- Video calls with indoor residents or mobile app users.
- Acts as a video doorbell, allowing visitors to ring and speak directly with those inside.pcworld+1
Indoor Touchscreen Uses
- View real-time outdoor footage and recorded videos.
- Manage user permissions (add/delete palm veins, finger veins, faces, passwords, etc.).
- Set AI scenarios and notification preferences.
The dual-screen design allows all family members, including elderly individuals unfamiliar with mobile phone operations, to intuitively use and manage the door lock.
Multiple Unlocking Methods, Balancing Convenience and Backup
In addition to triple biometric recognition, the Lockin V7 Max also offers various traditional and smart unlocking methods to handle different situations:
- Password Unlock: Supports fixed passwords, temporary passwords, and periodic passwords.
- Mechanical Key: As a physical backup in extreme circumstances.
- Lockin App:
- Bluetooth proximity unlock
- Remote unlock (requires internet connection)
- NFC Door Card (optional): Suitable for offices, subdivided flats, or multi-tenant scenarios.
- Xiao Tiancai Watch (specific models, requires separate purchase): Allows children to unlock with their watch, and parents can view entry/exit records in the App.
This diverse combination of unlocking methods allows the V7 Max to meet the needs of various usage scenarios, including homes, small offices, and short-term rental units.
