1: Specially designed for FPV from the start, no ugly cables and bare pcb board outside which cause interference. Fully sheild in a ALU metal case, no affect to other devices in your plane, UHF friendly.
2: Small size, light weight (58g only), the pan-tilt ready, easy to set up in your plane. Super crash resistant, easy to change the lens.
3: 7-16v wide range voltage input.
4: 142 degrees wide view angle with clear PAL/NTSC analog video output. AV out quality is more or less the same or better than most of cameras sold in the market, even better than some low-quality 700TVL cameras.
5: Radio-controlled HD recording, you can use one channel of your radio to control the HD to record as your wish during your flight.
6: Real HD, same resolution as GoPro:
16:9 1280×720 （60fps）
16:9 1280×720 （30fps）
So HD19 = 1 miniature HD camera + 1 high quality FPV camera, easy use as the normal mini analog camera, but also can record real HD video at the same time. What's more, it's affordable.
7: Firmware update easily.
