Hi @andrewjamez -
In order to see the camera stream, you’ll need to add a camera stream on the BlueOS Video Streams page. This should be the H264 stream (video2), and once configured will look like this:
Unfortunately, BlueOS does not support recording to the SD card by default - recordings are captured on the controlling computer with QGround Control or the Cockpit extension. You should be able to record locally if you were to run a command to capture the video stream to SD card, with gstreamer, but this may not result in as high quality a stream as recording is significantly more taxing than streaming for the Raspberry Pi 4.
