SJ11 4K Action Camera with Dual Screen & WiFi

Capture Every Action Moment in Sharp 4K Detail

The SJ11 Active Action Camera is designed for users who need reliable, high-quality footage in demanding environments. Record in true 4K (3840×2160) at 30fps, with support for 2K at 60/30fps, 1080p up to 120fps, and 720p up to 120fps for smooth slow-motion playback. A wide 170° lens (approx. 154° effective wide angle in certain modes) and F2.7 aperture help you capture more of the scene with clear detail, whether you are cycling, skiing, diving, or vlogging on the move.

The camera features a 2.33" touch screen on the back for quick control and playback, paired with a 1.3" front display that makes framing selfies and talking-to-camera shots straightforward. Built-in 6-axis gyro stabilization works with an intelligent anti-shake algorithm to reduce motion blur and vibration, delivering smoother, more stable video when shooting handheld or during high-impact activities. Active HDR video enhances contrast and detail in challenging lighting, while multiple white balance presets (Auto, Daylight, Cloudy, Tungsten, Fluorescent, Underwater) help you match the scene accurately.

With 2.4G/5G WiFi, you can connect to the companion app for remote control, quick file transfer, and live streaming. The camera body is waterproof to 5 m without a case and up to 30 m with the included housing, making it suitable for swimming, snorkeling, and most recreational diving scenarios. The device records in MP4 (H.264/H.265) and captures still photos in JPG with resolutions from 2MP up to 20MP. Photo modes include single, interval, continuous, and time-lapse shooting.

For flexible use, the SJ11 supports multiple video modes: normal recording, time-lapse, slow video, video+photo, car mode, loop video, night shooting, and pre-recording. Exposure compensation from +2.0 to -2.0 lets you fine-tune brightness. An 8x digital zoom allows closer framing when needed. The removable 1300mAh battery offers up to approximately 90-100 minutes of operation depending on settings and conditions, and the camera accepts microSD cards up to 128GB (card not included). A Type-C charging port, built-in microphone, and speaker support convenient audio capture and playback.

The SJ11 can also function as a webcam for PC, giving you a single device for outdoor action, live streaming, and desktop video calls. The compact body (approx. 65 × 44.5 × 31 mm, 108 g) mounts easily on helmets, bikes, and other gear. In the box you receive the action camera, waterproof case, frame mount, flat bottom bracket, lens protective cover, two helmet mounts, screw, two 3M adhesive stickers, USB cable, cleaning cloth, and user manual, so you can start recording right away.
