And in particular, the SJCam 4000 AIR also has the ability to record Slow Motion 1080P 60FPS and 720P 120FPS, which is not listed on the box. With this feature, we can film action movies quite interesting.

The main function of the action camera is mainly video recording so do not expect much on the quality of the picture. The photos show that the quality of the photos is average.

In low light conditions and with complex light sources, the video quality of the SJ4000 Air is reduced and the detail and noise increase as the SJ4000 AIR camera pulses the ISO to improve its brightness.
