Thanks for the detailed explanation of your video system.
 
I still have an old Nikon 35 mm outdoor camera ( water resistant) not 100% waterproof that has an infrared remote that turns in on, takes pics.

I have a little tripod for it that I could adapt to clamp to thwart or maybe even farthest pack forward?

No video or sound. but for selfie fish pics while solo it might just work?

I don't know that I want to carry all that gear when I should be looking to lighten my load.

But like I always say, if you don't mind carrying it, then bring what makes you happy. ;) ;D ;D
