A few things to note about the video capture device: - it hardware encodes to MJPEG at some ok but not great quality. Text becomes somewhat fuzzy but readable.

A few things to note about the video capture device: - it hardware encodes to MJPEG at some ok but not great quality. Text becomes somewhat fuzzy but readable. - a version with HDMI passthrough is available. It also has an extra optional power supply (micro usb) which is useful if you chain a dozen to one pi zero. - the usb only ones can be as low as £5 on ebay ($6.55) and £10 for passthrough. - it featured in an artcile by Micael Lynch which featured here on HN, where he explored the latency involved with such video caprure devices (https://mtlynch.io/tinypilot/ https://mtlynch.io/tinypilot/)
