All sorts of Prosumer video cams out there. Many of the news men/women have shifted to 1080 digital cams, and that pretty much gives you the best of both worlds in optical quality.
If tuff/H2Oproofness of your case is your most critical concern, then the GoPro line is the most popular.
When it comes to mountings, a small pocket tripod is about the best for image quality. Failing that, there is a 1/4-20 ball joint head that will give you a wonderful tool. I always use a monopod, so i put one of those on the top and stick it into a drilled out seat base for my boat pixs. I also carry a 1/4-20 C-clamp camera base for unusual situations.
Use a 32gig or a 64 gig chip if you’ve got the machine to process it at home. Most gaming machines will handle it well.
If you are doing any nite work, you may want ancillary batt power and i’d suggest 12V for ease of recharge. I use boat lites and lately LEDs a lot and color correct after the fact. Belt patts are fine if you’re getting paid for the time, but a PITA otherwise for prosumer quality.
