model: UC-541, CVBS video 384*288 640*512 1280*1024 optional, micro size 21*21mm, 22gram, 4mm and 9.X lens optional,A compact 21×21mm CVBS thermal camera module for non-U.S. FPV drones and UAV payloads. Designed for live analog thermal video through VTX, DVR, OSD or FPV goggles, not calibrated temperature measurement.
Goobuy UC-541 21×21mm CVBS FPV thermal camera module is designed for non-U.S. FPV drone builders and UAV payload integrators who need lightweight, low-latency analog thermal video through VTX, DVR, OSD, FPV goggles or AV ground-station monitors. It is a non-radiometric video-only thermal module for live viewing, not a calibrated temperature measurement camera.
The FPV Thermal Imaging Camera Module is a 21×21 mm, 22 g ultra-light solution that delivers low-latency analog CVBS output (PAL/NTSC), making it an excellent fit for FPV drones, autonomous robots, and energy monitoring systems.
Unlike digital modules, its analog CVBS video ensures near-zero delay, ideal for real-time FPV navigation and inspection flights. With support for multiple color palettes, robust thermal sensitivity, and flexible integration, it provides engineers with an affordable and practical tool for embedded thermal vision.21*21mm Mini CVBS thermal camera modules (256*192, 384*288, 640*512, 1280*1024, analog output) are ideal for drones, UAVs, and FPV systems where low latency, analog transmission is preferred over digital for real-time monitoring.The core advantages of the 22g ultra-light CVBS thermal imaging module (4 resolutions) are its extreme weight and high integration, making it a revolutionary solution for scenarios where weight and space are critical
Thermal Imaging (Uncooled Microbolometer): This core technology detects infrared radiation (heat) rather than visible light.
Solves: The inability to see in complete darkness, through smoke, fog, light dust, or certain thin materials. It also detects invisible temperature anomalies (hot/cold spots) and enables non-contact temperature measurement.
Meets Demand: Enhanced situational awareness in challenging visual conditions; predictive maintenance (identifying overheating components); security in absolute darkness; process control based on temperature; fire detection.

Buyers are responsible for confirming local import, export, aviation, radio transmission and thermal imaging regulations before purchase.
Many FPV drone builders already have a working analog video chain: VTX, DVR, OSD, FPV goggles or AV ground-station monitor.
Their real problem is not building a thermal imaging system from zero. Their problem is finding a small, lightweight CVBS thermal camera module that can fit the drone payload space and connect to the existing FPV video chain.
This module is designed for that specific need:
lightweight thermal visibility + CVBS analog video + non-radiometric live viewing + practical UAV integration.
CVBS is useful when the drone already uses analog FPV hardware.
Compared with USB, HDMI, Ethernet or MIPI thermal modules, CVBS can be simpler for FPV live viewing because it can connect into analog video paths such as:
This module is not designed for AI data processing or calibrated temperature analysis. It is designed for live thermal video viewing by the operator or pilot.
Actual end-to-end latency depends on the thermal core, VTX, DVR, OSD, wireless link, goggles and display processing.
For drone builders who need real-time thermal visibility through an existing analog FPV video chain.
For payload integrators testing a lightweight thermal module before designing a custom enclosure, fixed mount or small gimbal.
For teams that need thermal video to pass through existing analog FPV components.
For drone equipment companies building compact thermal viewing kits or upgrade modules for non-U.S. markets.

Note: This version is non-radiometric (video-only, no temperature measurement)

Best for balanced cost, compact size and practical FPV thermal viewing.
Better for higher image detail, longer viewing distance and more professional UAV payloads.
For higher-end projects where weight, cost, power, output mode and integration requirements are confirmed first.
The best resolution depends on drone size, payload limit, viewing distance, display device, lens FOV and target price.
A wide FOV lens is better for near-range awareness and easier FPV orientation.
A narrower FOV lens is better when the drone needs to observe heat signatures at longer distance or reduce wide-angle scene distortion.
Before selecting lens/FOV, please confirm:
Goobuy can discuss:
This module is not the right fit for:
Yes. This module is designed for analog FPV video chains using CVBS PAL/NTSC through VTX, DVR, OSD modules, FPV goggles or AV ground-station monitors. Compatibility should be tested with your actual VTX, goggles, DVR, OSD, cable length, video format and power supply.
No. This version is non-radiometric and video-only. It is for live thermal visibility, not calibrated temperature measurement, thermal mapping or temperature-data analysis.
384×288 is usually better for balanced cost and compact FPV projects. 640×512 provides better image detail and may be better for higher-value UAV payloads or longer viewing distance. The right choice depends on payload limit, display resolution, lens FOV, distance, power budget and target price.
CVBS is useful when the drone already uses analog FPV hardware such as VTX, DVR, OSD, goggles or AV monitors. USB, HDMI or Ethernet may be better when the project needs digital thermal data, AI processing, high-resolution recording or embedded computer integration.
The 21×21mm size refers to the thermal camera module board. Final installation depends on lens length, cable exit direction, connector, protective housing, heat dissipation, mounting bracket and payload space. Please send your payload bay drawing or photos before sample configuration.
Please send your target country/region, drone platform, payload weight limit, VTX/goggles/DVR/OSD model, PAL/NTSC requirement, power supply, mounting space, preferred resolution, lens/FOV requirement, cable/connector need, sample timeline and expected batch quantity.
It can be evaluated for permitted non-U.S. drone thermal viewing, pilot awareness, observation or recording where local laws allow. It is not a certified life-safety, firefighting, rescue, military targeting or weaponized-use system.
No. This page is intended for non-U.S. FPV and UAV integration projects. Goobuy does not position this module for the U.S. market or U.S.-regulated drone procurement projects. Buyers must confirm local compliance before purchase.
If your drone already uses analog FPV goggles, VTX, DVR, OSD or AV ground-station monitor, send Goobuy your project background instead of only asking for a unit price.
We can evaluate whether this micro CVBS thermal module fits your non-U.S. FPV / UAV project, or whether another USB, HDMI, radiometric or higher-resolution thermal module is more suitable.
Send your FPV drone video-chain details to Goobuy. We will help check whether this CVBS thermal module is suitable for your non-U.S. UAV project.
