5. Installation

This section details the physical connection and initial setup of the FM225 module.

5.1 Schéma de brochage

Refer to the diagram below for the pin assignments for both UART and USB interfaces.

5.2 Connexion du module

1. Connexion électrique : Connect the module to a stable DC power supply within the range of 5.5V to 9V at 1A. Ensure correct polarity.
2. Interface de communication :
   • UART: Use the provided connection wires to interface with your host system via UART. Refer to the pinout diagram for TX/RX and GND connections.
   • USB: Connect the module to your host system using the provided USB cable. This interface is typically used for data transfer and configuration.
3. Montage: Securely mount the module in its intended location, ensuring the camera lenses have a clear, unobstructed view of the area where facial recognition will occur. Consider the optimal recognition distance (0.3m to 1.1m) and height (1.35m to 2.20m).

6. Mode d'emploi

The FM225 module operates primarily through commands sent via its communication interfaces. Specific software or SDKs provided by the manufacturer are typically required for full functionality, including face enrollment and recognition.

6.1 Face Enrollment

To enroll a new face into the module's memory:

1. Ensure the module is powered on and connected to your host system.
2. Use the manufacturer's provided software or send the appropriate UART/USB commands to initiate the enrollment process.
3. Position the subject's face within the recognition distance (0.3m to 1.1m) and within the recognition angle (supports multi-angle input).
4. Follow the on-screen prompts or command responses to complete the enrollment. The module can store up to 100 facial features.

6.2 Reconnaissance faciale

Once faces are enrolled, the module can perform recognition:

1. The module continuously scans for faces within its field of view.
2. When a face is detected, the module compares it against its stored facial features.
3. If a match is found with sufficient accuracy (98.85%), the module will output a recognition result via the chosen communication interface.
4. The module's live detection feature helps prevent recognition from photos or videos.

7. Entretien

The FM225 module requires minimal maintenance to ensure optimal performance.

• Nettoyage: Gently wipe the camera lenses with a soft, lint-free cloth. Do not use abrasive cleaners or solvents.
• Environnement: Veillez à ce que l'environnement de travail reste dans les plages de température et d'humidité spécifiées.
• Mises à jour du micrologiciel : Vérifiez périodiquement les instructions du fabricant. website pour toute mise à jour du micrologiciel disponible afin d'améliorer les performances ou d'ajouter de nouvelles fonctionnalités.
