Overview: The SJCAM C400 is a 3-in-1 vlogging camera designed for creators who need a compact handheld and action-ready POV cam. It records in 4K Ultra HD for cinematic detail and uses a 154° ultra-wide, distortion-free fixed lens with an f/2.0 aperture to improve low-light performance and deliver a pleasing shallow depth of field. A built-in HDR mode enhances dynamic range for richer footage. Stabilization & Shooting Modes: Built-in 6-Axis Electronic Image Stabilization (EIS) with horizon correction keeps footage steady during fast movement or shaky shooting conditions. The C400 supports multiple capture modes including loop recording, slow-motion, time-lapse, burst shooting, and timed shooting. Video & Photo Specs: Video resolutions available are 4K/30fps, 2K/60fps, 1080P/120fps, and 720P/120fps. Photo output is 20MP (interpolated). Special shooting options include slow motion (2K@60fps), time-lapse, and loop recording. Connectivity & Remote Preview: The camera features ultra-fast 5G WiFi and dual-band support (2.4GHz/5GHz) for rapid transfer of high-resolution photos and 4K video. An innovative wireless video transmission system separates the handheld controller from the camera so you can preview and adjust settings remotely on the controller. Remote control and live preview are managed through the SJCAM Zone app (iOS/Android). Battery & Recording Time: Equipped with a high-performance battery, a single charge delivers up to 7 hours (460 minutes) of continuous shooting power for extended outings and live streaming. Recorded runtime at 4K/30fps is approximately 420 minutes. Durability & Waterproofing: The C400 has an IPX8 rating (5m without case) for splash- and rain-resistant use; with the included waterproof case it can be used to a maximum waterproof depth of 30m, suitable for underwater shots when housings are sealed correctly. Display, Storage & Accessories: The camera includes a 2.29-inch HD touchscreen for easy framing and menu navigation. It supports microSD cards up to 256GB (Class 10 or above required). Included in the bundle are a waterproof case, helmet mount, flat adhesive mount, and USB-C cable. Practical Tips: Always charge with the original USB-C cable to help prevent overheating. Verify housing seals before any underwater use and rinse the case after exposure to saltwater. For wireless transfers and remote operation, use the SJCAM Zone app (5G WiFi supported).
