5. 자주 묻는 질문
1. What does “Athermal Lens” mean?
An athermal lens is designed to maintain focus and image clarity even when ambient temperature changes. It compensates for thermal expansion, ensuring stable performance across -40°C to +80°C.
2. Why is the refresh rate only 25Hz instead of 60Hz?
Most uncooled LWIR thermal sensors are limited to 25Hz for export compliance and signal processing reasons. Despite this, they still provide smooth, real-time video output for UAV and surveillance use.
3. Can this module output HDMI or IP video instead of CVBS?
This version supports analog CVBS output. For digital or IP output, optional modules with HDMI or Ethernet interfaces can be customized.
4. Is this module suitable for drone integration?
예. With its lightweight 38g design, wide voltage input (4.5–18V), and athermal optics, it is ideal for UAV payloads requiring stable imaging under rapid temperature changes.
5. What is the detection distance of 1.1km based on?
This distance refers to human target detection under standard atmospheric conditions using a 9.1mm lens. Actual performance may vary depending on humidity, ambient temperature, and target size.
6. 결론
그만큼 Mini-640-CVBS Thermal Module offers excellent compatibility with the customer’s specified requirements.
