The SJCAM SJ20 is an action camera with two lenses for daytime and nighttime shooting, capable of recording up to 4K/30 fps. Thanks to 6-axis stabilization with EIS, a 135° wide-angle view, 8× digital zoom, and dual displays, it is suitable for sports, travel, and content creation. With the protective housing, it is waterproof, and via 5 GHz Wi‑Fi you can easily connect it to the SJCAM Zone app.
The SJCAM SJ20 action camera is designed for filming in various lighting conditions. It uses two lenses: a daytime lens with an f/2.0 aperture for bright and detailed shots, and a nighttime lens with an f/1.3 aperture, which helps capture more light when filming after dark. Both lenses support recording up to 4K at 30 fps, and the night mode is complemented by the SuperNight function for better use of available light.
During dynamic activities, you will appreciate the combination of a 6-axis gyroscope and electronic image stabilization (EIS), which helps compensate for vibrations and keep footage smoother. For convenient control and composition checking, there is a 2.29" touchscreen as well as a front 1.3" display suitable for selfies and vlogs.
The camera also offers practical modes and features for different usage scenarios:
- 135° wide field of view and 8× digital zoom for switching between a wide shot and detail.
- Connection via Wi‑Fi 2.4 GHz / 5 GHz and control in the SJCAM Zone app (real-time preview, downloading and sharing recordings).
- Modes such as timelapse, slow motion, Car Mode, loop recording, motion detection, and vertical recording.
- Waterproof up to 5 m and up to 30 m with the waterproof housing (suitable for water activities).
