The camera is the size of my thumb, and is clipped onto my belt just below my belly button. With 2Gbytes of flash memory, it can run for quite a long time.
That clip came from an 8 minute continuous file of half a gigabyte, so I could shoot about 25 minutes of video before needing to download it and clear the memory. Like the cameras on smart phones, it needs good light for decent filming, but if all I care about is recognisable people synchronised with the sound...
I'll be extracting a new clip from the same run, showing the cross-Pyrennean dog - promised long ago to Mark
Quite fun, if the subject is more important than the technical quality. My dog-walking clips feel a bit odd, because the camera follows my hip movements - but when I hold it in my hand as I walk along I get plenty of camera shake, anyway. You get what you pay for in both money and effort - a gyro-stabilised camera carried on my shoulder is way beyond either my means or my interest (:=>
