Understanding the Customer’s Needs
The customer is looking for a compact, high-performance thermal imaging module that delivers real-time, low-latency video suitable for UAV or mobile platform applications.
Key points that define their needs include:
- High frame rate (60кадр/с) – crucial for smooth real-time imaging and tracking moving objects.
- Compact size (25.8mm cube) – perfect for integration on drones or gimbals.
- Wide voltage input (4.5–18V) – suitable for direct battery operation.
- CVBS output (NTSC) – allows plug-and-play connection with COFDM video transmitters.
- Excellent environmental tolerance (-40℃ to +80℃) – ideal for outdoor or tactical operations.
This module’s 640×512 разрешение, 12μm pixel pitch, и <50mK thermal sensitivity indicate it is a professional-grade LWIR sensor, capable of detecting human targets up to 1.1km away.
Рекомендация продукта: COFDM Wireless Solution
To fully utilize the capabilities of this thermal camera, we recommend integrating it with our H.265 Ultra-Low-Latency COFDM Transceiver Module.
- Input interface: ЦВБС (analog video input)
- Transmission delay: так низко, как 30–80ms
- Диапазон: до 15 км ЛОС (extendable via Mesh mode)
- Выход: HDMI or AV at the ground control station
🔗 Recommended Product: Mobile COFDM Video Transmitter & Получатель
Suggested System Configuration
Thermal camera (CVBS output) → COFDM transmitter → Mesh relay UAVs (необязательный) → COFDM receiver → HDMI display
This configuration provides a стабильный, long-distance, real-time thermal video link, even in partially obstructed (НЛОС) условия.
Приложения
- UAV and drone thermal inspection
- Border surveillance and perimeter security
- Search and rescue operations
- Firefighting and disaster monitoring
- Wildlife observation and night patrol
Часто задаваемые вопросы
1 квартал: Can the thermal camera output digital video?
А1: The current version provides CVBS analog output. A digital upgrade (HDMI/IP) can be achieved by adding a video converter board.
2 квартал: Is the latency low enough for real-time control?
А2: Да, when combined with our H.265 COFDM transmitter, total end-to-end latency can be reduced to 30–80ms, suitable for FPV control or tracking.
Q3: Can it operate in harsh outdoor conditions?
А3: Да. The module operates from -40°C to +80°C and uses an athermal lens to ensure focus stability under temperature changes.
Q4: Is it compatible with existing drone telemetry or OSD systems?
А4: Да. The COFDM system supports video + telemetry transmission, enabling overlay and control data on a single RF link.
Заключение
This 640×512, 60fps LWIR thermal camera module, combined with a COFDM wireless transmission system, is an excellent solution for UAV and mobile surveillance applications. It provides high sensitivity, низкая задержка, and robust environmental adaptability — delivering reliable thermal video even in demanding missions.
