I tried that too. Currently querying the image quality with them as the one I have won't even get a numberplate in broad daylight at low speed. Very different to the footage on their website.
It sounds like they updated it recently-ish. A different Sony sensor, apparently, which has improved the video quality. Haven't tried mine yet but will use it soon and post a video.
Nice, thanks. Will take a punt on it, can't be worse than the chilli tech bullet cam...
