5.2.2 Motion Threshold
Options can be ignored
The simplest way to obtain a report of motion in the video is to click Search after clicking
Fetch; see procedure 50 in 5.2, above. Use of Motion Threshold or Masking that Detects
Motion, explained in this section and 5.2.3, are optional. If this is your first read-through
of these options, please skip to p. 5–7 for 5.3: Search Report, and come back to find out
about the search options later. See figure 41.
Sensitivity. Threshold for reporting movement. Moving the slider right of center picks up
smaller movements. Setting the slider to the far left turns off motion search. Slider range
of magnitudes: 1 to 100.
Interval. Minimum amount of time, in seconds, between reports. Two or more
occurrences of movement within the interval are reported as a single item in the motion
search report. Adjust the interval as needed. Range: 1’’ to 9999’’ (or 2h:46’:39’’).
