i'd like to have a small wearable camera that's on all day, snapping away, even if it was 3fps, and have some kind of voice recognition/hands free operation. Could wipe the storage daily. Wide fov, fast lens and optical stabilisation would be nice. The Xiaomi Yi's (and other Chinese cameras using Ambarella/HiSilicon/Allwinner SoCs) are cheap and pretty scriptable, but a bit too big/obvious. Anyone know of a camera that would work? This Google one doesn't take pictures of everything, and is pretty expensive for what it is.
