OceanTools C4 range of cost-effective underwater Internet Protocol cameras capture colour HD (including 1080p) video in low light level conditions. It has rapidly become established as the IP camera of choice for many industries including offshore renewables, salvage, military, and scientific research.

• C4-10: fixed zoom with a 4mm lens fitted as standard for a 73° diagonal field of view

• C4-20: motorised 2.8–12mm varifocal optical zoom lens for close-up inspection

• C4-30: ultra wide angle fisheye lens and hemispherical window for a nearly 180° field of view

Video is streamed using standard Internet Protocols such as the RTSP protocol, with a remote configuration interface. A single subsea connector supports data and power, with optional Power over Ethernet (PoE) for easy integration. Multiple IP cameras networked underwater can share a common copper or fibre optic uplink to the surface.
