The SJCAM C400 takes a different approach to the action-camera market. Instead of simply shrinking down a conventional action camera, it combines a tiny detachable camera with a battery grip that doubles as a larger monitor and wireless controller. The result is a versatile setup aimed at casual vloggers, travelers, and everyday creators.
It records in 4K, features six-axis gyro stabilization, has a rotating touchscreen, and can deliver up to seven hours of claimed battery life with its grip. It also comes with a generous selection of mounting accessories. However, the C400 isn’t without compromises, particularly when you push it beyond casual shooting.
6Waterproofing Requires an Extra Step
The C400 itself isn’t natively waterproof. You need the supplied waterproof case for underwater shooting, with the case supporting depths of up to 30 meters.
That’s useful for swimming and other water-based activities, but it does add bulk and makes the C400 less convenient than action cameras that can be used directly in water without a case.
For normal travel and everyday use, though, this isn’t likely to be a major concern.
App Connectivity Is Fine, But Not Perfect
The SJCAM Zone app lets you monitor and control the camera from your phone, which is useful when the camera is mounted out of reach. It also provides another way to change settings and manage recording.
The app isn’t always perfectly reliable and can occasionally disconnect, but this is more of a minor annoyance than a major drawback. The C400 remains usable without depending on the smartphone app.
