The competition in the traditional smart lock market has long since moved beyond fingerprint and facial recognition unlocking. With the deployment of AI big data models in home hardware, door locks are shifting from passively executing unlocking commands to actively sensing, analyzing, and interacting with home security terminals. The DESSMANN Kirin R9 AI Smart Butler Lock is a flagship product that deeply integrates AI intelligence into the door lock, combining door locking, peephole monitoring, voice control, and biometric recognition into one device.
Appearance and Craftsmanship: Dual-Screen Interaction, Breaking Free from the Stereotype of Traditional Door Locks
The Kirin R9 features a unibody curved aluminum alloy design with an AG etching process, making it fingerprint-resistant and oil-resistant. It offers multiple color options to match various home styles, including wooden doors, security doors, and minimalist luxury interiors.
The most distinctive feature is the dual-screen design: a 2.1-inch dynamic external screen displays cute animated emoticons, weather information, custom messages, holiday reminders, and provides a visual representation of the door lock status; the internal 5-inch IPS high-definition screen automatically illuminates when a visitor presses the doorbell, allowing them to see the visitor without needing to take out their phone.
The door lock retains an internal quick-open handle for rapid mechanical unlocking in case of power outages or emergencies; the internal deadbolt requires a press confirmation to prevent accidental activation by children, demonstrating a focus on home safety. The overall design features a concealed mechanical keyhole, resulting in a seamless, unified panel.
Unlocking Experience: Suitable for the whole family, 11 unlocking methods covering all scenarios
The Kirin R9 is equipped with 3D face and palm vein dual biometric recognition, combined with curved fingerprint, password, temporary password, APP, and mini-program unlocking methods, totaling 11 methods to meet the needs of different family members, including the elderly, children, and those with sweaty hands.
3D Structured Light Face Unlock: Financial-grade security, unaffected by backlighting or dimly lit hallways. Even with hands full of packages or shopping bags, simply stand in front of the door for automatic unlocking. Wearing a thin mask will not trigger unlocking, enhancing security.
Palm Vein Recognition: Non-contact recognition, collecting subcutaneous blood vessel information from the palm, eliminating the need to touch the lock. Suitable for children too short for the face module, elderly people with worn fingerprints, or those with sweaty or peeling hands; simply reach out to unlock, making it suitable for use by the elderly and children.
GPTfinger2.0 Curved Fingerprint: Curved sensor with a larger contact area, significantly improving the success rate of recognition for sweaty hands and shallow fingerprints compared to ordinary flat fingerprints, reducing the probability of recognition failure.
Temporary Password and One-Time Password functions are suitable for housekeeping services and short-term visits from relatives and friends. Passwords automatically expire, eliminating the need for additional keys.
AI Security Core: Dual-Camera Sentinel Doorbell 2.0 for Comprehensive Doorway Monitoring
Security is the core capability of smart locks. The Kirin R9 features the Shotax Sentinel Doorbell 2.0, employing a dual-camera setup: a 4MP upper camera and a 2MP lower camera, both with 150° wide-angle lenses. This addresses the pain point of a single doorbell camera not being able to detect ground-level packages.
The upper camera identifies visitors, while the lower camera monitors the ground area, capturing packages and takeout placed at the door. It supports infrared night vision, ensuring clear images even in low-light conditions.
AI human detection is a key feature: it can distinguish between family members, strangers, and delivery personnel, automatically capturing and recording images of people loitering or lingering at the door, and pushing these images to a mobile app. It also supports remote video calls; when a visitor rings the doorbell, the user can directly answer the call on their phone for remote intercom functionality. Some versions are equipped with intelligent radar, which can define detection zones, filter pedestrian traffic in the building, reduce invalid alarm pushes, and minimize message annoyance.
AI can recognize takeout delivery placement events and automatically remind users of the delivery status at their door; it supports event recording playback, saving all family members’ entry and exit records and abnormal events outside the door, allowing users to monitor the door’s activity both at home and when away.
AI Smart Butler Miya: The door lock is no longer just a lock.
The Kirin R9 integrates a large model, using the wake word “Miya,” integrating a voice intelligence agent into the door lock itself, hence its name “AI Smart Butler Lock.”
More than just simple voice broadcasts, it can:
Voice Q&A: Check the weather, answer simple life questions;
Custom voice messages: Record messages in the app, automatically broadcast when family members open the door, suitable for family message reminders;
Custom welcome messages, interactive door opening and closing expressions, creating a sense of ritual at home;
Voice response for delivery scenarios: When a visitor rings the doorbell, the door lock can respond with a voice message, indicating that the package has been placed at the door and indicating a monitored mode.
Unlike ordinary smart locks that can only announce “unlocked/locked,” this AI-powered smart lock can perform simple home interaction tasks, transforming the lock into a small interactive terminal at the home’s entrance.
Battery Life and Hardware Security
Battery life utilizes the D-Power intelligent battery life system, featuring a dual-battery solution: a 7750mAh removable main battery and a 1000mAh built-in backup battery. When the main battery is removed for charging, the built-in backup battery maintains all lock functions, preventing the lock from becoming unusable while charging. It automatically enters a super power-saving mode when the battery is low, extending standby time and alleviating the battery drain caused by frequent video recording.
For hardware security, it employs a C-level direct-insertion lock cylinder, incorporating a full suite of smart lock security mechanisms, including anti-hacking, automatic locking after trial and error, duress alarm, and abnormal unlocking alarm. The lock body features a built-in Longting high-torque motor 2.0, which automatically adapts to door resistance, resulting in lower opening and closing noise, protecting the lock’s mechanical structure, and extending its lifespan.
Summary of Advantages and Disadvantages Based on Actual Testing
✅ Advantages
3D face + palm vein dual biometric recognition, suitable for unlocking methods for the whole family; Dual-camera peephole, covering both visitors and ground surfaces, solving the limitations of traditional peepholes; AI smart home interaction, with messaging and voice response, expanding the scope of door lock functionality; Dual-battery design, charging does not interrupt door lock use, solving battery life pain points; Dual screens, allowing users to view the outside without a phone, user-friendly for the elderly.
⚠️ Disadvantages
High power consumption across all functions; frequent 24-hour recording will shorten battery cycle time; AI voice interaction is only suitable for simple scenarios, with limited ability to handle complex conversations; High-end pricing, higher cost threshold for users with limited budgets; Some advanced radar and pan-tilt functions are differentiated by version, requiring differentiation between the Elf Edition, Premium Edition, and Pan-tilt Edition when purchasing.
