This is the Raspberry Pi v2 camera module, modified with a custom lens holder and wide-angle lens that’s much better suited to use on ROVs. The original field of view of the camera is about 62 degrees horizontally – this lens extends that to about 110 degrees.
The lens holder and lens are preinstalled and focused. No setup required.
This camera works great with the Raspberry Pi 3! The included cable plugs directly into the Raspberry Pi 3 board for easy setup.
