Looking at this now... There seems to be no sleep mode, so I'd have to=20 have it shut off until needed, and I've not found anything yet that=20 indicates how long it would take to start recording from power-up. I'm also unsure where the data will be held...there's no mention of=20 on-board storage, and I doubt an Arduino can capture video fast enough=20 though SPI. Thinking I might pick one up to tinker with... when it's back in stock=20 though. Cheers, -Neil. On 3/7/2018 11:50 PM, Ryan O'Connor wrote: > JPEG usually means still frames.
