minimum_motion_frames

  • Type: Boolean
  • Range / Valid values: 1 - 1000s
  • Default: 1
  • Group: Motion Detection

Picture frames must contain motion at least the specified number of frames in a row before they are detected as true motion. At the default of 1, all motion is detected. Valid range is 1 to thousands, but it is recommended to keep it within 1-5., Picture frames must contain motion at least the specified number of frames in a row before they are detected as true motion. At the default of 1, all motion is detected. Valid range is 1 to thousands, but it is recommended to keep it within 1-5.

Note that the picture frames are buffered by Motion and once motion is detected also the first frames containing motion are saved so you will not miss anything.

The feature is used when you get many false detections when the camera changes light sensitivity or light changes.

Experiment for best setting. Even though Motion accepts large values you should set this to a relatively low number (below 10). For each step larger than 1 Motion reserves space in RAM for the picture frame buffer. If you have a large value Motion will miss many frames from the camera while it is processing the all the pictures in the buffer.
