Smart locks did not emerge as an overnight innovation but have undergone a lengthy development process. From mechanical locks to electronic locks and now smart locks, each technological advancement has aimed to improve both security and convenience.

• Mechanical Lock Era: As the earliest form of locks, mechanical locks were simple in structure and durable but relatively insecure, vulnerable to picking or key duplication.
• Electronic Lock Era: Electronic locks introduced electronic components and password technology, enhancing security but still faced risks of password leaks or cracking.
• Smart Lock Era: Smart locks integrate biometrics, wireless communication, and intelligent control technologies, enabling keyless access, remote control, and real-time monitoring, significantly improving user experience and security.

TTLock smart locks are IoT-based locking devices that connect to smartphones or other devices via Bluetooth or WiFi, offering remote control, real-time monitoring, and smart management capabilities. Key features include:

• Multiple Unlocking Methods: Supports fingerprint, password, RFID card, Bluetooth, and physical key access.
• Remote Control: Users can lock or unlock doors remotely via a mobile app.
• Real-Time Monitoring: Tracks lock status, including access logs and alarm notifications.
• Smart Home Integration: Can sync with other smart home devices for automated scenarios (e.g., turning on lights when unlocked).
• Security Measures: Employs multi-layer encryption and anti-tamper alarms.

TTLock offers diverse unlocking options, each suited for different scenarios:

• Fingerprint Recognition: Uses advanced biometric technology to prevent spoofing.
• Passcodes: Supports permanent, temporary, and recurring codes.
• RFID Cards: Contactless access via Mifare or NFC cards.
• Bluetooth: Low-energy Bluetooth for extended battery life.
• Physical Keys: Backup keys for emergencies.

The TTLock app enables:

• User management (adding/deleting users, permissions).
• Access logs and alarm notifications.
• Remote locking/unlocking.
• System settings (language, time, volume).

TTLock uses SSL/TLS encryption for data transmission and storage, with secure key management protocols.

Combines biometrics, passcodes, RFID, and Bluetooth for layered security.

Built-in sensors trigger local and remote alerts if forced entry is detected.

Recommendations to mitigate risks:

• Regular firmware updates.
• Strong passwords and two-factor authentication.
• Secure home WiFi networks.
• Routine log checks.

Most models use AA/AAA batteries; replacement steps include:

1. Open the battery compartment.
2. Remove old batteries.
3. Insert new batteries (observe polarity).
4. Close the compartment.

Factors affecting battery life:

• Lock model and usage frequency.
• Number of users and WiFi usage.
• Battery quality (alkaline/lithium recommended).

Emergency measures include:

• Backup keys.
• External power banks (for USB-compatible models).

Includes fingerprint/password failures, RFID malfunctions, or Bluetooth disconnections.

For example:

• Clean fingerprint sensors.
• Reset forgotten passwords.
• Re-register RFID cards.
• Restart devices for connectivity issues.

Contingency plans:

• Secondary smart locks or physical keys.
• Temporary access codes.
• 24/7 customer support.

Verify door compatibility, gather tools, and review manuals.

Account registration, user permissions, and network setup.

Works with lights, thermostats, security systems, and voice assistants.

Examples:

• "Home" mode (lights on when unlocked).
• "Away" mode (activate security when locked).
• Guest access management.

Potential developments:

• Advanced biometrics (facial/iris recognition).
• AI-driven behavioral analysis.
• 5G/WiFi 6 connectivity.
• Quantum encryption.
