SJCAM SJ4000 4K Action Camera with 3-Axis EIS

The SJCAM SJ4000 is a compact action camera built to record crisp 4K video and high-resolution 40MP photos with 3-axis electronic stabilization and a 170° super wide-angle lens.

This model bundles two rechargeable batteries, a 32GB SD card, and a helmet accessory kit so you can start shooting right away. It offers a wide range of recording modes — from time-lapse and loop recording to motion detection and underwater capture — and connects to your phone via the SJCAM Zone app for remote control and quick sharing. The camera’s IP68-rated housing lets you record underwater to 30 meters, and a 5x digital zoom expands composition options when you need closer framing.

How does the SJ4000 stabilize footage for fast movement?

The SJ4000 uses built-in 3-axis electronic image stabilization (EIS) to reduce shake during running, biking, or motorcycling. EIS compensates for tilt, yaw, and roll electronically, producing smoother clips without heavy gimbals.

• 3-axis EIS for steadier handheld and helmet footage
• 6G fisheye lens combined with software correction to reduce distortion
• Multiple frame-rate options up to 4K30 for choosing smoother motion or higher detail

What shooting modes and resolutions are available?

The camera supports 4K30, 2K30, 1080p30, 720p30 and lower resolutions, plus a 40MP still-photo mode. It includes time-lapse, burst, interval, loop recording and a dedicated underwater mode for optimized color and exposure while diving.

• 4K30 and 2K30 video for high-detail capture
• Burst, interval and time-lapse for creative stills and long-duration capture
• Loop recording and dash-cam use for continuous recording needs

How water-resistant and durable is the SJ4000 for underwater use?

The camera ships with an IP68-rated waterproof housing that protects it to depths of 30 meters (98 feet). The case lets you power the camera and access modes while preserving clear image quality underwater.

• IP68-certified housing for diving and snorkeling to 30m
• Underwater mode to adjust color and exposure automatically
• Robust accessory mounts included for helmets, bikes and handlebars

How do WiFi and accessories improve workflow and sharing?

Use the SJCAM Zone app to preview, control, and download footage wirelessly within roughly 33 feet. The included dual batteries and 32GB card extend shooting time and let you swap power quickly on longer outings.

• WiFi connectivity for remote preview and one-touch capture via app
• Two 900mAh batteries for longer continuous use and hot-swapping
• 32GB microSD included; supports up to 128GB after formatting

This kit is aimed at outdoor enthusiasts, motorcyclists, water-sports participants, and creators who want a ready-to-use action camera with stabilization and dive-ready housing. It fits people upgrading from entry-level cams who need better stabilization, or anyone who wants a versatile, cost-effective tool for adventure footage and social sharing without complicated setups.
