For 800 / 1000 USD you can get a nice 4K PTZ CCTV camera for coparison, which is a larger and way more elaborate housing - 20 X optical zoom - a couple of DC step motors and what not + a memory card slot.
Personally as a camera geek i feel many of these "e - scopes" are pretty darn expensive VS say a high end action camera or Dash camera system.
EDIT: i just saw the video flies are in AVI format,,,,,,, damn near fell of my office chair, i have not handled any camera ( dash or action or CCTV ) in years that use AVI
It do at least support a 256GB memory card, so that is good, but surprised a lot to not see H264 or H.265 for the video files.
