Helmet Video Cameras, Two-Way?

[einsign]

Can anyone recommend a Two-Way camera for recording commuting journeys each day, after one or two "incidents" with car drivers I think it would be handy to keep a record in the future.

The only one I have found so far is: http://www.bikeradar.com/commuting/news/article/tw...

I guess you'd have to practise walking around with a book balanced on your head.

I think a lid-mounted forward facing and a bike-mounted rear facer would make more sense.

Unless you ride with a very upright position, you'll only get a view of the sky from the rear camera if it's the same unit - as above, helmet mounted front and bike mounted rear would be my choice.

I would have thought if they design the two-way camera correctly the angle of lenses should both be adjustable to avoid filming the sky.

Any suggestions for two separate cameras, or even just one for my helmet for now.
