Camera waterproofing - prototype

Position

A little testing with position before I change the mount to try and avoid the horizon exactly lining up with the top of the windscreen.

This is with my mount right side up and the camera base level with the bottom of the roll-bar:

...at the same height and in front of the roll-bar; my preferred location at the moment:

...and sitting about 10cm below the bar, roughly driver eye height, good view but will make the mounting more complex:

I think I'm going with level/in front of the bar - temporarily I'm going to simply mount the U clamp upside down and do a little testing.

Waterproofing

I'm not looking for hermetically sealed, waterproof, more a little wind protection and preventing the camera being lost due to a little rain. The first thing to try is a small acrylic display box 10cm x 7cm x 7cm - I have two of them from eBay:

First picture is the control, taken without the box & second through the side of the acrylic; noticeable loss in detail on the grass & bricks close up - might not be noticeable when moving though? The acrylic does scratch like crazy though so may not be practicable other than keeping the rain off:

 Dremel out to make some modifications & the mk1 waterproof box is begun:

Short test video; The box is having an effect - especially reflections; possibly off the top surface which needs masking out:

This version is the prototype to check things out - if the position is good I may re-work the mount so it enters via the bottom of the box and reduce the chance of water ingress. As much weather is pulled in from the back of the car due to its aerodynamics as comes in from the front. I also have some glass UV & polarising filters on order from eBay which may mount directly in front of the lens and reduce the impact to picture quality.
