To adjust how much motion is required to trigger motion recording, adjust the
values for the following parameters:
•
Sensitivity—
the change in a pixel required for that portion of the
image to be considered changed. The Sensitivity value is expressed as
a percentage times 100. For example, a value of 100 indicates a 1
percent change, 5000 indicates 50 percent, and so on. A brightness
change from black to white would be a change of 10000, or 100
percent. This comparison is performed for all pixels in each image.
•
Unmasked Area % for Motion—
the percentage of an image that
must change as compared to the reference image for motion recording
to be triggered. For example, a value of 10 percent means that one
tenth of the pixels in the image must change enough as compared to
the reference image for motion to be detected.
•
Reference Count—
how often the reference image is updated. A
setting of 100, for example, means that every 100th image becomes
the new reference. The 99th image would be compared to the first
image, whereas the 101st image would be compared to the 100th
image.
