One aspect of the Prism I liked was being able to leave one of the QRM (Quick Release Mount)
wedges screwed to the underside of the camera, even when it was clipped into the helmet
mount. While riding I could reach around, unclip the camera from the helmet and slot it into a
QRM-equipped ball mount fixed to the scooter; which I set up to record alternative angles. This
flexibility puts all rival mount systems in the shade.
Once you’ve watched helmet-cam footage for more than five minutes you’ll realise the
importance of changing shooting angles. You must do this to maintain interest without the
viewer feeling that they are part of some Clockwork Orange torture experiment. The key here is
to remember that long sections of uncut Point-Of-View (POV) filming are best reserved for
moments of extremely high drama, or pornography.
The full Prism kit comes with a massive and superbly well-designed selection of mounts, many
of which I left at home simply because being able to swap from helmet to alternative, adjustable
mounts front and rear of the scooter was enough. Take my word for it; whatever you need, from
clamps to suction mounts, will probably be in the kit.
WEATHER RESISTANCE
The Prism has another advantage over most rivals in that you don’t need to use a waterproof
case for slight inclemency. Sena claim it can handle 1-metre submersion without its clear plastic
case, but that depends how securely you fitted its push-in rubber rear USB cover. On the few
occasions it did rain when I had the camera fitted I suffered no water ingress problems. Having
said that, I’ve read other reviews where enough moisture managed to get inside the Prism while
raining to fog the lens. The tip to remove any fogging is to leave the camera in a bag of uncooked
rice overnight to let Uncle Ben suck the badness out. For my part it simply made more sense to
put the camera away when it was peeing down because rain riding footage is about as sexy as
watching fat, old men in the shower. Maybe that works for you though. Weirdo.
My test Prism did come with a waterproof plastic case but since I didn’t plan to go under the sea,
I left it at home. Also, the waterproof case does not clip into the clamp-on helmet bracket like the
bare camera does; which restricts its usefulness.
For most adventure situations I reckon you could ride using the camera without its waterproof
case, except perhaps falling off in a river. In which case you’ve got other things to worry about
anyway…
