Discreet Dash Cam

Not 100% sure on where to put this topic, and I can't seem to find anything about it elsewhere. Feel free to move it if required.

I am looking for a discreet Dash Cam package, I am sure I had seen one before that had 5 tiny little pinhole cameras. I am not after anything big and chunky in the windscreen, as I can't stand anything looking clumsy, and ideally I would like it all round and maybe an internal camera as well.

The way I see it, 5 pinhole cameras on long cables and a vdr in the boot would be a perfect option, probably not cheap but surely someone is making it somewhere.
