2. Safety Information

• Ensure the power supply meets the specified requirements (DC5.5V~9V@1A) to prevent damage to the module.
• Do not expose the module to extreme temperatures outside the working range (-20°C to +60°C) or storage range (-30°C to +70°C).
• Avoid environments with high humidity (above 93% without condensation) to prevent electrical short circuits.
• Handle the module with care to prevent physical damage. Avoid dropping or subjecting it to strong impacts.
• Do not attempt to disassemble or modify the module, as this will void the warranty and may cause malfunction.
• Keep the module away from water and other liquids.

5.2 Connecting the Module

1. Power Connection: Connect the module to a stable DC power supply within the range of 5.5V to 9V at 1A. Ensure correct polarity.
2. Communication Interface:
   • 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. Mounting: 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. Operating Instructions

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 Facial Recognition

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. Maintenance

The FM225 module requires minimal maintenance to ensure optimal performance.

• Cleaning: Gently wipe the camera lenses with a soft, lint-free cloth. Do not use abrasive cleaners or solvents.
• Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
• Firmware Updates: Periodically check the manufacturer's website for any available firmware updates to improve performance or add new features.
