Technical Specifications

Expanded Product Description

1. Seamless Smart Upgrade

The Q5 is designed for the modern minimalist. It replaces your old-fashioned round door knob without needing to saw or drill into your door. It’s compatible with standard wooden or steel doors, making it an ideal choice for apartments, offices, and bedrooms.

2. Advanced Biometric Security

Unlike older optical scanners, this lock uses semiconductor fingerprint technology. This is the same tech used in smartphones, meaning it is more secure and recognizes prints faster—even for the elderly or children with lighter prints. The AI algorithm learns over time, becoming more responsive the more you use it.

3. Tuya Ecosystem Integration

As a Tuya-compatible device, you can manage the lock directly from your smartphone.

• Remote Unlock: Let guests in even when you aren’t home.
• Access Logs: See exactly who entered and at what time.
• User Management: Add or delete fingerprints through the app.

4. “Life-Proof” Power Features

Worried about being locked out? This lock features three layers of protection:

• High-Endurance Battery: A built-in lithium battery with an energy-saving algorithm for long standby times.
• USB-C Emergency Port: If the battery hits 0%, simply plug in a power bank to give it enough juice to unlock.
• Mechanical Override: A hidden keyhole at the bottom of the handle for a traditional metal key.

5. Versatile Operating Modes

• Passage Mode (Always Open): Perfect for office hours or when hosting a party; the door stays unlocked so people can come and go freely.

Privacy Mode: Provides peace of mind when you’re inside, ensuring no one can enter from the outside without your permission.
