Underwater Stereo Camera

The MarineSitu C3 is an underwater stereo vision camera that captures depth information and high-resolution color imagery. It uses a pair of stereo cameras to perceive depth, along with a center color camera for high resolution imagery, all housed in a rugged enclosure rated to 1000 meters depth. Designed for marine robotics and research applications.

The C3 ships ready to install with a mounting bracket for the BlueROV2 and a preinstalled WetLink Penetrator. It connects over Ethernet, so an onboard Ethernet Switch is required for operation.
