The Caddx Polar Micro Digital FPV Air Unit Camera Kit supports the DJI HD FPV Video System. The set includes the new starlight Polar camera and the Caddx Air Unit Micro, which is the official replacement for the DJI Air Unit which is discontinued.
The Caddx FPV Air Unit has all the features and performance of the original, featuring an ultra-low-latency high-definition digital image transmission, 720p/60fps video recording, and eight frequency channels, allowing eight pilots to fly simultaneously.
The ‘Polar’ camera, is the first DJI FPV HD compatible camera to be designed for night flying. Utilising a 1/1.8 inch ‘Starlight’ sensor with a min illumination of just 0.00003 lux, the Polar will be able to still see when you can’t! While the camera has been optimised for low-light conditions, the image quality in daytime is still very good.
