a compact powerhouse for creators on the go

Videographers, creators, hobbyists, and adventurers often switch between an action camera and a handheld camera to get the right shot. While the classic mount-only action camera design works, it typically requires additional accessories and limits shooting flexibility. The SJCAM C400 aims to change that.

The SJCAM C400 is one of the few handheld action cameras available today, allowing users to capture dynamic content while walking, traveling, or engaging in sports. Its three-in-one modular design allows the main camera to detach into a compact mini action cam and pair with a wireless handheld controller, giving creators more options with less gear.

Whether you’re a full-time content creator, travel vlogger, or someone who prefers a minimal setup, the C400 makes it easy to shoot from almost any angle, nearly anywhere.

A handheld action camera with a 3-in-1 design for versatile shooting

What sets the SJCAM C400 apart is its flexible modular build, which combines three shooting configurations without adding unnecessary bulk. While many action cameras use a fixed screen and rigid mounting options, the C400 introduces a 2.29-inch rotatable touchscreen, a wireless controller handle, and a detachable mini camera—a meaningful upgrade for creators who want more control and mobility.

This three-part system lets users quickly adapt to different shooting conditions on the move—without swapping mounts or carrying extra rigs. For casual users and professionals, this means faster setup and more intuitive shooting.

The C400 supports three main shooting modes:

Handheld action camera mode

In handheld mode, the camera mounts onto the wireless grip, making it easy to frame shots and control recording while walking or standing—offering a familiar camcorder-style experience. This configuration also extends the camera’s battery life thanks to the integrated battery in the handle.

The handheld approach provides more flexibility than traditional mount-only action cameras and is especially useful for vloggers who frequently move between scenes and environments.

Despite its versatility, the C400 remains compact and lightweight:

● The detachable camera weighs just 1.9 oz, fitting easily into a pocket.

● Combined with the wireless handle, the full setup weighs under 7 oz.

The small footprint means it’s travel-friendly, easy to carry, and comfortable for long shooting sessions without fatigue.

Mini action camera mode: Ideal for POV and multi-angle shots

Detach the camera from the grip to use it as a traditional mountable action camera. With included accessories—such as frame mounts, helmet clips, curved and flat mounts, and a waterproof case—the camera can be attached to helmets, bikes, skateboards, dashboards, clothing, and more.

The wireless handheld controller can also act as a remote, allowing users to preview and trigger recordings from a distance without touching the mount.

Wireless handheld controller mode

The wireless handheld controller allows real-time preview and recording control from up to 8 meters away. Whether the camera is mounted on a moving gear or stationary on a tripod, users can monitor framing and capture the exact shot they want without being next to the camera.

There is also a more budget-friendly C400 Pocket model, which maintains handheld and mountable functionality but excludes the wireless controller.

The C400 supports multiple resolutions and frame rates:

• 4K (3840×2160) at 30fps
• 2K at up to 60fps
• 1080p and 720p at up to 120fps for smooth slow-motion playback

It also includes up to 8× zoom, plus time-lapse, slow motion, loop recording, burst shooting, and motion detection modes.

To support motion-heavy environments, the camera features six-axis gyro stabilization with updated algorithms for reduced shake—even in less-than-ideal lighting.

Smart connectivity, storage, and long battery life

The C400 delivers up to 7 hours of continuous 4K recording when used with the battery grip—significantly longer than most action cameras at this resolution, which typically average around 2 hours.

The camera also features:

• Dual-band Wi-Fi (2.4GHz/5GHz) for faster transfers and app control.
• Support for microSD cards up to 512GB.
• Easy viewing, downloading, and remote operation via the SJCAM Zone app.

Together, these features help creators stay focused on capturing content rather than managing equipment.

Who is the SJCAM C400 for?

The C400 is a strong fit for:

• Vloggers who want flexible handheld and POV recording.
• Travel and adventure creators who shoot for long periods.
• Users who value portability, simplicity, and extended battery life.

It also supports YouTube live-streaming, making it suitable for everyday creators and long-form travel storytellers alike.

Ready for your next adventure

With its versatile 3-in-1 modular design, long battery life, stabilization performance, and crisp 4K recording, the SJCAM C400 offers creators a flexible and portable action camera that adapts to nearly any shooting style.

Whether you choose the flagship C400 or the compact C400 Pocket, you’re getting a camera designed to capture every moment—any angle, anywhere.
