You can just see the brown video cable looping to the underside of the frame where the camera is attached.
She’s standing on a perspex box as part of some experimenting as to why this happens:
It’s taking at least 4.5 seconds before the video feed kicks in (if at all). Here the video data is only logged. What’s plotted here is the cumulative distance; what’s shown is accurate in time and space, but I need to investigate further why the delay. It’s definitely not to do with the starting up of the camera video process – I already have prints showing when it starts and stops, and those happen at the right time; it’s either related to the camera processing itself, or how the FIFO works. More anon as I test my ideas.
