- Frame Rate: The module operates at either 30Hz or 60Hz (or 50Hz depending on model/configuration), providing smooth real-time thermal imaging.
- Image Modes: The MINI2 offers multiple image modes. Consult your system's software or the module's communication protocol documentation to select the optimal image mode for your specific application (e.g., observation, temperature measurement).
- Lens Options: The module supports various lens options and customer-developed lenses, allowing for flexibility in field of view and application-specific requirements.
The MINI2 module is versatile, suitable for applications such as vehicle-mounted thermal cameras, security systems, and night vision.
5. Maintenance
To ensure the longevity and optimal performance of your thermal camera module, follow these maintenance guidelines:
- Cleaning the Lens: Gently clean the lens with a soft, lint-free cloth specifically designed for optics. Use a small amount of lens cleaning solution if necessary. Avoid abrasive materials or harsh chemicals.
- Environmental Protection: While the module is designed for robust environments (operating temperature -40°C to +80°C, 5%~95% non-condensing humidity), protect it from extreme conditions beyond its specified limits.
- Storage: When not in use, store the module in a dry, cool place within the specified storage temperature range (-50°C to +85°C). Keep it away from direct sunlight and corrosive substances.
- Physical Inspection: Periodically inspect the module for any signs of physical damage, loose connections, or debris accumulation.
- Firmware Updates: Check with the manufacturer or seller for any available firmware updates that may improve performance or add new features.
6. Troubleshooting
If you encounter issues with your MINI2 thermal camera module, refer to the following common troubleshooting steps:
- No Image Output:
- Verify the 5V power supply is correctly connected and providing stable power.
- Check all video and communication cable connections for secure fit and correct pinout.
- Ensure the receiving display or host system is correctly configured for the module's output type (PAL/NTSC, DVP, USB, etc.).
- Poor Image Quality:
- Clean the lens carefully as described in the Maintenance section.
- Ensure the module is operating within its specified temperature range.
- Check for any obstructions in the module's field of view.
- If using digital output, verify software settings for image processing and display.
