Raspberry Pi motion detector
main example of working with MMAL -> https://github.com/tasanakorn/rpi-mmal-demo.git

Device:
  Raspberry Pi 2 Model B Rev 1.1
  Raspberry Pi Camera Module
  3,5” RPi LCD 480×320

FPS
  motion-h264-detect-opencv ~ max 4 FPS
  motion-h264-detect-vector ~ max 29 FPS
  motion-final ~ 15 FPS

Examples ( directory - 'images' ) :
creates files in the directory(variable "DirSave"):
  *-f.jpg, *-f-small.jpg - first frame motion detect
  *-s.jpg, *-s-small.jpg - frame after ~ 1.5sec from the motion detect
  *.mp4 - Video
  * - yyyymmdd_hhmmss

Start the alert in ~1.5 sec:
  running script(send.sh), parameter($1): "varable Dirsave"+20231009_142258-s.jpg
  running script(sendvideo.sh) after video file recording is complete, parameter($1): "varable Dirsave"+20231009_142258.mp4
