Yes, higher performance cameras are being actively investigated. We haven’t gotten to the stage of setting up a supply contract for a chosen option though, so I can’t give a timeline on when we’ll be releasing our next camera product.
That said, the BlueOS camera manager is quite versatile, and can support H264-encoded USB cameras, with experimental support for MJPEG and YUYV encoded streams through RTSP, and also supports quite generic stream redirection of IP cameras (e.g. connected via an Ethernet Switch), so there are a range of options you could try out if you want an alternative to our Low Light HD USB Camera. It also supports multiple simultaneous camera streams, although receiving those at the control station computer requires something other than QGroundControl.
The camera section here covers several relevant considerations. The main additional one is bandwidth limitations in the vehicle’s communications hardware, because if you’re trying to send more data than the hardware can handle you could end up with vehicle control issues and intermittent telemetry.
