[chbot] Video cameras

[Marshland Engineering]

As most robots have some kind of camera, you may have the answer to this. We 
run 8 motorcycle race track meetings a year and 1 street race.

We are looking at cameras to video the corners in case of accidents. Any 
suggestion on cheap cameras that will video for an 8 hour period. We can add 
an external battery if needed. Preferably low res and 15 frames a second to 
ensure we don't overrun a 32 gb stick.  We will need about 8 or so. Most 
specs on the web don't really cover the complete range of options the camera 
has.

Cheers Wallace.
