LOCKIN is a global smart-home security brand that specializes primarily in smart door locks, biometric access systems, video smart locks, and connected home-entry technologies. The brand is operated by Yunding Technology, a Beijing-headquartered smart-lock and home-security company in China. LOCKIN positions itself around the concept of making residential security “Safe. Simple. Smart. For the Whole Family.” 1

The company is particularly known for its development of biometric smart-lock technology, including palm-vein recognition, fingerprint authentication, facial recognition, smartphone/app control, video door monitoring, and other keyless-entry methods. In recent years, LOCKIN has increasingly differentiated itself through palm-vein recognition and AI-enabled video security rather than relying exclusively on conventional fingerprint-based smart locks. 2

LOCKIN’s official website currently describes the company as having 12+ million products sold worldwide, operations in 50+ countries, more than 800 published patents, and a workforce in which approximately 51% of employees are involved in R&D. These are company-reported figures and should be treated as such. 3

LOCKIN’s history is closely connected with Yunding Technology, which has operated in the smart-lock industry before the establishment of LOCKIN as an international consumer brand.

According to regional LOCKIN company materials, the underlying company was founded in May 2014, originally under the name Yunding Technology. The company subsequently developed its smart-lock business and expanded its manufacturing and international operations.

Some of the company’s reported milestones include:

• 2014 – Yunding Technology was founded.
• 2017 – The company was selected as a member of the Xiaomi ecosystem.
• 2018 – It reported shipping more than 2 million units worldwide and subsequently raised Series D funding led by Baidu.
• 2019 – The company became a participant/member of the Zigbee Alliance and introduced the LOCKIN global consumer brand.
• 2021 – Its Chongqing manufacturing operation expanded with additional production-line capacity.
• 2022 – LOCKIN reported expanding its business into 12 countries and regions.
• 2025 – LOCKIN introduced the Veno Pro, described by the company as the world’s first solar-powered palm-vein video smart lock, at CES.

The precise corporate history can look slightly different across LOCKIN’s regional websites because some pages describe the parent company, manufacturing business, and consumer brand together.

LOCKIN’s stated vision is:

“Connecting and guarding all family members through technological innovation, becoming the most trusted partner for families worldwide.” 4

The brand’s positioning is therefore broader than simply selling electronic door locks. LOCKIN presents the smart lock as a central component of a connected home-security system.

Its technology is designed around several ideas:

• Keyless entry
• Biometric authentication
• Remote access
• Video door monitoring
• AI-assisted detection
• Smart-home integration
• Family access management
• Reduced dependence on physical keys

This has allowed LOCKIN to position itself somewhere between a traditional lock manufacturer and a consumer smart-home technology company.

Palm-vein recognition

One of LOCKIN’s most distinctive technologies is palm-vein recognition, branded by the company as Venokey™.

Instead of requiring a user to touch a fingerprint sensor or remember a password, the system identifies the user’s palm/vein pattern. LOCKIN says its Venokey system can unlock in approximately 0.17 seconds with 99.9% accuracy, with the latter figures attributed to TÜV Rheinland certification on its product materials.

This technology has become one of LOCKIN’s primary differentiators in the smart-lock market.

Fingerprint recognition

LOCKIN also offers conventional biometric authentication through fingerprint sensors. Earlier LOCKIN designs incorporated concealed semiconductor fingerprint technology into the door-handle mechanism, including its One-Grip Unlocking concept.

Facial recognition

Selected LOCKIN products support 3D facial recognition, providing another hands-free method of unlocking.

This is particularly relevant for households where users may be carrying groceries, luggage, children, or other objects and do not want to use a key or touch a fingerprint reader.

Video monitoring

LOCKIN’s higher-end locks incorporate cameras and doorbell functionality.

The company’s LockinCam™ technology is described as providing a 180° 2K ultra-wide camera view, intended to reduce blind spots around the entrance.

This transforms the smart lock from a simple access-control device into a form of video door security system.

AI detection

LOCKIN also promotes LockinAI™, which uses local AI algorithms for motion/target recognition and notification.

The company says local processing can provide faster notifications while helping preserve privacy by reducing reliance on cloud-based processing for certain functions.

The Veno range is currently one of LOCKIN’s flagship product families.

It includes several configurations, including:

• Veno – palm-vein smart lock
• Veno Go – more affordable palm-vein model
• Veno Plus – palm-vein video smart lock
• Veno Pro – flagship palm-vein video smart lock
• Veno Solar Palm – solar-powered palm-vein smart lock
• Veno Solar Face – solar-powered facial-recognition smart lock

LOCKIN’s current product portfolio therefore covers both conventional smart-lock applications and higher-end biometric/video systems.

A notable recent direction for LOCKIN is solar-assisted smart locks.

The company’s newer Veno Solar products are designed to reduce the need for conventional battery charging. LOCKIN markets the Solar Palm and Solar Face models as capable of providing up to 10 years of power without regular charging, although real-world performance will naturally depend on installation conditions and usage.

LOCKIN is also moving toward becoming part of the broader smart-home ecosystem rather than operating as an isolated lock.

The company says its newer products work with platforms including Apple, Google and Alexa through Matter, the cross-platform smart-home standard.

This potentially allows a LOCKIN lock to participate in automated home scenarios—for example, unlocking the door could be associated with lighting, climate-control, or other smart-home actions.

LOCKIN places considerable emphasis on engineering and manufacturing.

The company currently claims:

• 800+ published patents
• 51% of employees in R&D
• 15 million units of annual production capacity
• Presence in 50+ countries
• More than 12 million products sold worldwide
• Approximately 10 years of technology and design development

Earlier company materials described the Chongqing manufacturing operation as being expanded through multiple production lines, with planned capacity eventually reaching approximately 15 million units annually.

These figures are LOCKIN/company-reported statistics, rather than independently verified industry measurements.

Design is another important part of LOCKIN’s positioning.

The company says its products and design work have received recognition from organizations and competitions including:

• Red Dot
• iF Design Award
• Golden Pin Design Award
• IDA
• Other international design programs

LOCKIN’s regional materials specifically cite awards dating back to at least 2018.

The emphasis reflects the brand’s attempt to combine industrial design with security hardware, rather than treating the smart lock purely as a functional piece of door hardware.

LOCKIN has expanded beyond China into international markets.

Its own materials describe operations or availability across 50+ countries, while regional operations have been established in markets including the United States and Singapore.

Singapore is one particularly visible overseas markets. LOCKIN Singapore operates retail, installation and support services and markets the brand for HDB apartments, condominiums, landed homes and offices. 1

The Singapore operation also offers models adapted to local requirements, including digital locks incorporating fingerprint, password, NFC, Bluetooth, Wi-Fi, facial recognition and palm-vein authentication.

LOCKIN has developed a relatively strong local presence in Singapore’s digital-door-lock market.

Its Singapore operation provides:

• Product sales
• Installation
• Technical support
• After-sales service
• Physical retail/showroom locations
• Digital locks for HDB, condominium and other residential applications

LOCKIN Singapore currently describes itself as a major digital-lock brand in the Singapore market and says its products are certified for fire-safety requirements applicable to HDB fire-rated main doors. Specific certification and suitability should nevertheless be checked for the exact model and door configuration before installation. 5

LOCKIN’s business can broadly be understood as a combination of:

Hardware + biometrics + software + connected services + installation/support.

Unlike a conventional mechanical-lock manufacturer, LOCKIN’s products can involve several layers:

1. Physical security hardware — lock mechanisms, cylinders, handles and deadbolts.
2. Biometric authentication — palm vein, fingerprint and facial recognition.
3. Connectivity — Bluetooth, Wi-Fi and other wireless technologies.
4. Mobile software — smartphone-based access and management.
5. Video security — cameras and doorbell functionality.
6. AI — motion and person/target detection.
7. Smart-home integration — including Matter-compatible ecosystems.
8. Installation and after-sales service.

This combination is central to LOCKIN’s identity as a smart-home security company rather than merely a digital-lock manufacturer.

The easiest way to understand LOCKIN’s market positioning is to compare it with a conventional smart-lock company.

A basic smart lock typically focuses on:

Fingerprint + PIN + card + mobile app

LOCKIN increasingly focuses on:

Palm vein + face + fingerprint + video + AI + remote access + smart-home integration

Its strongest technological differentiator is arguably its investment in palm-vein recognition. LOCKIN says it became a global leader in vein-recognition smart locks and cites Frost & Sullivan research for its claim of being No. 1 in global vein-recognition smart-lock sales based on 2022 unit sales. 2

That distinction is important: the “No. 1” claim is specifically about vein-recognition smart-lock sales, not necessarily the entire global smart-lock market.

LOCKIN’s current brand identity can be summarized through three words:

Safe

The fundamental purpose remains physical home security and controlled access.

Simple

The company attempts to eliminate everyday friction associated with keys, passwords and conventional access methods.

Smart

LOCKIN adds biometrics, cameras, AI, mobile connectivity and smart-home integration to the traditional door lock.

Its official tagline reflects this directly:

“Safe. Simple. Smart. For the Whole Family.” 1

LOCKIN describes its broader mission as using technology to “connect and guard” family members, explicitly mentioning not only adults but also seniors, children and even pets. 6

This is significant because it positions the door lock as part of a broader family-security ecosystem, rather than merely a replacement for a metal key.

As of 2026, LOCKIN appears to be moving in three major directions:

• Biometric innovation: especially palm-vein recognition.
• Integrated home security: combining locks, cameras, doorbells and AI.
• Lower-maintenance smart locks: particularly through solar-powered models.

Its newer products show a clear attempt to solve some of the longstanding problems associated with smart locks—battery replacement, inconvenient authentication, limited visibility around the door, and fragmented smart-home ecosystems.

LOCKIN is a Beijing-based global smart-home security brand under Yunding Technology that specializes in biometric and connected smart locks, with palm-vein recognition, video monitoring, AI and solar-powered technologies forming the core of its current product strategy.
