Waterproof Housing for SJCam SJ4000 Series – Protective Underwater Case

This waterproof housing is designed for SJCam SJ4000 series action cameras, providing a sealed enclosure for use in wet conditions and underwater. The case preserves access to basic controls and the camera lens while preventing water, splashes and rain from reaching the camera. It enables secure mounting on compatible mounts and supports common water activities such as snorkeling, diving and kayaking where a protective casing is required.

Advantages

The housing offers full water resistance to depths specified by the manufacturer, a clear optical-grade front window for minimal image distortion, and reliable sealing with an integrated rubber gasket. The case construction includes secure latches and a reinforced body to protect the camera from impacts and pressure while maintaining access to shutter and mode buttons. Its compatibility with standard mounts enables straightforward attachment to helmets, handlebars and chest mounts.

How to use

Avoid exposing the case to extreme heat or direct sunlight for prolonged periods, and always follow depth limits and safety guidance associated with the housing and the camera model.
