FPV Camera Buying Guide

Digital vs. Analog Systems

• Analog: This system is cheaper and simpler, offering an extremely low, stable latency (often under 30ms), which is the core reason competitive racers still use it. The image is low-resolution (measured in TVL) and noisy.

• Digital (HD): Systems like DJI and Walksnail offer significantly higher resolution (720p/1080p) and a cleaner image with better low-light performance. Latency can be slightly higher and may vary, but the clarity is vastly superior.

Key Camera Terminology

• Latency: This is the time delay from image capture to goggle display. Low latency (under 25ms) is the single most critical factor for manual/Acro flying, as high delay can lead to crashes.

• Field of View (FOV): FOV determines the width of the picture you see while flying. A wider FOV (155°–165°) improves situational awareness for racing, while a narrower FOV (130°–150°) is better for cinematic flying with less distortion.

• Aspect Ratio (4:3 vs 16:9): The 4:3 ratio provides a taller vertical view, which helps pilots judge the drone's attitude during aggressive maneuvers. The 16:9 ratio offers a wider, more cinematic feel.

• Resolution (TVL vs. Pixels): Analog cameras use TVL (Television Lines) to measure resolution, which is limited by the analog signal to a low quality. Digital cameras use standard pixel resolutions (720p/1080p), offering a much clearer image.
