SJCAM C400 Pro Launched: The Upgraded 4K Handheld Action Camera with Bigger Sensor & Detachable Design
SJCAM has officially released the C400 Pro on August 11, 2026, the upgraded successor to the popular C400. This new model keeps the flexible 3-in-1 detachable design that users loved while delivering meaningful improvements in image quality, stabilization, audio, and usability.
With the slogan “One camera, dual forms—vision from the heart,” the C400 Pro is positioned as a high-performance 4K handheld vlogging camera designed for everyday creators. It targets office professionals, students, and travel enthusiasts who want a compact yet versatile camera for travel and daily content creation.

What’s New in the C400 Pro?
The C400 Pro is not a minor refresh. It brings several important upgrades over the original C400:
| Feature | C400 Pro | C400 |
| Sensor | 1/1.8″ CMOS | 1/2.8″ CMOS |
| Lens | 160° FOV, f/1.9 | 154° FOV, f/2.0 |
| Stabilization | SteadyMotion V2.0 | SteadyMotion V1.0 |
| Vertical Video | 2K@30fps / 1080P@30fps | Max 1080P@30fps |
| External Microphone | Supports M4 Wireless Mic | Not supported |
| Voice Control | Supported | Not supported |
| Battery (camera only) | Up to 120 min (4K 30fps) | Up to 172 min |
| Battery (with Controller) | Up to 300 min (4K 30fps) | Up to 437 min |
| Weight & Size | Same (189g with controller) | Same |
The larger 1/1.8-inch sensor is the most significant hardware upgrade. It captures more light, resulting in cleaner images, better dynamic range, and improved low-light performance compared to the smaller 1/2.8-inch sensor on the C400. Combined with a wider 160° field of view and a brighter f/1.9 aperture, the C400 Pro delivers noticeably better overall image quality.
Key Features of the SJCAM C400 Pro

Innovative Detachable 3-in-1 Design
The C400 Pro continues the modular concept of its predecessor. You can use it as a compact pocket-sized action camera, detach the camera module for pure POV filming, or attach the wireless handheld controller for comfortable vlogging with real-time preview and extended battery life. The controller can also function as a power bank, giving you up to 5 hours of 4K recording when combined with the camera.
Superior Image Quality
Powered by the new 1/1.8″ CMOS sensor, the C400 Pro records sharp 4K video at 30fps and supports vertical shooting at 2K or 1080p. The 160° ultra-wide lens captures more of the scene, making it ideal for immersive travel and lifestyle footage.
160° Ultra-Wide Field of View
The C400 Pro features a 160° FOV lens with an f/1.9 aperture. This wider perspective allows you to capture more of the scene in every frame—ideal for immersive travel footage, group shots, and dynamic action sequences—while still maintaining natural-looking results.
SteadyMotion V2.0 Stabilization
The upgraded SteadyMotion V2.0 algorithm provides smoother footage during walking, cycling, or handheld movement. It is a clear step forward from the V1.0 system on the original C400.
Better Audio Options
The C400 Pro supports the SJCAM M4 wireless microphone (sold separately). This is a major improvement for vloggers who need clearer voice recording. Note that it does not support traditional wired microphones.
Convenient Operation
- Rotatable 2.29-inch touchscreen for easy framing and power-on
- Front 1.3-inch screen
- Voice control (supports multiple languages, including English)
- 5GHz Wi-Fi for faster file transfer
- Real-time preview and remote control via the handheld controller
Practical Everyday Features
- Waterproof to 30 meters with the included case
- microSD support up to 512GB
- Compact and lightweight design (camera body is highly portable)
- Rich accessory package included out of the box
Who Is the C400 Pro For?
The C400 Pro is ideal for:
- Daily vloggers: who record fitness sessions, cooking, lifestyle moments, or student life
- Travel creators: who need a lightweight camera that can switch between handheld and POV modes
- Beginners and intermediate creators: looking for a versatile, high-value 4K camera without the complexity or price of premium flagships
Its combination of pocket portability, detachable flexibility, and improved image/audio performance makes it especially suitable for people who want one camera that can handle multiple shooting styles.
C400 Pro vs C400: Is the Upgrade Worth It?
If you already own the original SJCAM C400 and are satisfied with its performance, the upgrade may not be essential. However, the C400 Pro is clearly the better choice for new buyers. The larger sensor, improved stabilization, voice control, and wireless microphone support address the most common requests from creators who want higher image quality and cleaner audio.
The slightly shorter battery life on the camera unit is a trade-off for the more advanced sensor and processing, but the combined system with the controller still delivers solid endurance for most daily and travel use.
Final Thoughts
The SJCAM C400 Pro successfully builds on the flexible foundation of the C400 while delivering meaningful upgrades where they matter most—image quality, stabilization, audio, and ease of use. With its “one camera, dual forms” design, it offers genuine versatility for everyday vlogging and travel content creation.
If you are looking for a compact, high-performance 4K handheld action camera that can adapt to different shooting styles without requiring a bag full of accessories, the C400 Pro is one of the most compelling options in its class.
