4. Modes de funcionament i característiques
The InfiRay P2 Pro app offers various modes and settings to enhance your thermal imaging experience.
4.1 Mode simple
In Simple Mode, the app automatically displays the hottest, coldest, and average temperatures within the frame. You can easily capture photos and videos.
4.2 Professional Mode
Professional Mode unlocks advanced measurement and analysis tools, providing greater control over your thermal data.
- Point Measurement: Tap on the screen to add up to three arbitrary points and display their exact temperatures.
- Mesura de línia: Draw a line on the screen to display the highest, lowest, and average temperatures along that line. Up to three lines can be drawn.
- Area Measurement (Frame): Draw a square or rectangular frame to detect the highest, lowest, and average temperatures within that specific area. Multiple frames can be added.
- Scale Bar (DIY Bar): When enabled, you can slide your finger on the side of the screen to set the highest and lowest temperature range for the displayed palette. Objects outside this range will appear grey/black. (Note: This function does not work in White-hot and Black-hot palette modes).

4.4 Image and Measurement Settings
Access the settings menu to customize your experience:
- Unitat de temperatura: Switch between Celsius (°C), Fahrenheit (°F), and Kelvin (K).
- Alarma de temperatura: Set high and low temperature thresholds. The phone will sound an alarm if the image temperature exceeds or falls below these thresholds.
- Prevenció de cremades: This crucial feature automatically cuts off the sensor if it detects exposure to extremely high-temperature radiation sources (e.g., direct sunlight, very hot objects) to prevent damage. A warning will prompt on the screen.
- Configuració de la imatge: Adjust brightness and contrast for clearer thermal images. Enable/disable Automatic Shutter Switch and Continuous Image Capture.
- Variable Correction (Emissivity): Modify settings for emissivity, ambient temperature, and target distance based on the material being measured (e.g., default, wet soil, glass, red brick, skin, white paper, black cloth, wood, water surface, or custom).
- Flip de la imatge: Flip and rotate the image by any angle (0°, 90°, 180°, 270°).
- Mode de mesura: Select between High Image Quality, Wide Range, or Automatic Switching for optimal performance.
5. Media Capture and Analysis
5.1 Enregistrament de fotos i vídeos
The InfiRay P2 Pro allows you to capture both thermal photos and videos directly within the app. Videos are recorded at a smooth 25Hz frame rate and can include audio from your device's microphone.
5.2 Gallery and Secondary Analysis
All captured images and videos are stored in a dedicated gallery within the app. From here, you can perform secondary analysis on saved thermal images, adding or modifying measurement points, lines, and frames. You can also generate reports and easily share your results.
5.3 Visible Light Image Overlay
The app supports a picture-in-picture function, allowing you to view a real-time visible light image from your phone's camera alongside the thermal image. This helps in better contextualizing the thermal data.
