SD card and file handling

I have just installed a Sentry 2 camera; amazing value, think I might get another!

  1. Does anyone know how to download videos from it?
  2. How do I manually delete videos from it?
  3. How long does it take to fill up the 128Gb SD card?
  4. What format are the video files?
    Is there a detailed manual available?
    That’s all for now!!

All good questions, I know I’d like the answers to. I have not found any kind of user manual, I’m just stumbling my way through. It seems as though many of the things netvue says the camera will do, it does not. I’m yet to have a video recorded to my SD card.
