The main camera (Birdfy Cam 2 Pro) is equipped with two lenses: the one on top is a 3MP lens with 2K resolution that can rotate and track movements. The bottom one is a 2MP lens with 1080P resolution featuring a wide-angle, fixed view, similar to the BF 1's camera, where the frame remains static.
The side camera (Birdfy Cam 2) has a single 2MP lens with 1080P resolution, like the one on the BF 1. It captures wide-angle videos, letting you admire the birds from a side view.
