Cheap Helmet Camera Recommendation

[andybesy]

Hi,

Can anyone recommend a cheap helmet camera?

I'm on a budget and so limited to the cheap ebay stuff, rather than brands like Go Pro or Drift etc.

I only really want it for for insurance purposes and so don't need great quality, just sufficient.

My main requirements are:

- Can charge and run permentently from bike battery (USB, cigerette lighter etc - I don't mind getting cables etc separately)
- Can record while charging
- Waterproof, or waterproof casing (unless suitable to be installed inside helmet)

And my wish list nice to haves would be:

- Rolling recording, so it records say past 1 hour on rolling basis
- Starts recording automatically when powered on

Any recommendations, advise, suggestions welcome.

Thanks, Andy
