Implementing 4K camera with zoom and autofocus

Hello, I write in this forum because I’d like that you gave me a suggestion on a camera. I want to replace it with one with 4K resolution and that has zoom and autofocus. Can someone give me a suggestion on which model to use?


Hi, i need to switch to 4K too, but raspberry pi H264 encoder does not support (4k)
today it’s only possible to encode 1080p@30fps

(T_T) :persevere:

We wait for the new update :boom:

Hi there,
We use 4K cameras (25FPS) with zoom and autofocus in separate small housings (65mm diameter, 100-150mm long depending on requirements).

The camera modules themselves can be used in the BR enclosures, but need some reorganising to fit, so the separate housings are a more convenient method to use the cameras. The video feed can be shown in QGroundControl or VLC.

They are fitted with a Blue Trail Engineering connector for easy connection (Subconn also available), and can have a Fathom board installed inside if you want to connect directly to the ROV comms system (otherwise you can install a network switch onboard the ROV). They are currently being machined and will be available soon, get in touch if you’d like more info.
