===== Requirements =====

  * ideally 4K 120fps
  * give up resolution before fps

==== Action Camera ====
=== Go Pro 10 and friends ===
  * GoPro Bones isn't waterproof
  * GoPro 8 and 9 would work but the price difference doesn't warrant
    * GoPro 10 can do 4K at 120fps
  * Go Pro 10: $350 on GoPro site
  * Go Pro 10 overheats without a fan. [[https://www.thingiverse.com/thing:5080770|one possible fan case maybe]]
=== Other options ===

  * [[https://www.bhphotovideo.com/c/product/1542251-REG/paralenz_par10201_vaquita_dive_camera.html|this one]] has good specs
==== Mirrorless SLR ====
[[https://www.bhphotovideo.com/c/buy/digital-cine-cameras/ci/28624/N/3705627354|In the $2K to $6K range]] there are cameras that do high fps at excellent resolution. Issues:
  * Communication: there is some sort of standardized api
  * streaming: unclear what their streaming rates are and that never seems to be in the specs
  * not waterproof --- too fragile for rugged outdoors
Some choices:
