So youtube is a great way to archive even if it is a private video.
There is also vimeo.
I prefer helmet cam as I can look around.
I don't use two cameras because that becomes your life trying to edit the thing. I do have rides and then record it with a couple of cameras.
I have almost every version of Contour I like them because I can rotate the lens.
They're small and have a great helmet mount that acts as a sticker.
Contour Roam is great.
A quick flick of the switch the thing turns on and records.
Its waterproof and the batter lasts up to 3 hours.
The lens spins 180 degrees
The lazer is now a line
metal tripod ( i have a metal tripod that is a clamp. )
Cons
battery not replaceable
All of my previous editions have had with record button switch problems. (easy to record in your bag with count our roam)
File size is huge (but that is ok)
I find the rear camera neat, but we still are a 10 decade away of making this feasible in making it simple.
Here is a rear facing camera
I use a tripod mount that clamps to my rear rack.

Notice no license plate?
I want a forward facing camera to show I didn't go through a stop light or stop sign so that is my reasoning behind getting a the front. as priority.
Helmet camera follows my eyes
