motion detection is disabled. The Enabled/Disabled status is displayed in the bottom right corner of
the Motion Settings window.

Motion detection is computed independently in multiple detection zones on a square grid. The largest
grid supported for any CBC camera model and image size is 8 by 8. The actual grid for any particular
model is determined by the chosen zone size (a drop-down list in the lower right corner of the Motion
Settings screen) and the camera’s pixel resolution. The actual grid is displayed in the lower left corner.
When motion is present, the Motion Settings window displays green marks (selectable between crosses
and boxes) in the zones affected.
 A privacy mask can be set up to block motion detection in some of the zones by drawing a rectangle
with the mouse (by left-clicking and holding down the mouse button). The privacy mask is marked
with red crosses. A more complex shape can be created by drawing multiple rectangles. Erasing the
mask (or part of the mask) is done by drawing a rectangle with the right mouse button.
Motion detection settings apply only to the camera which number is displayed in the Camera field on
the left of the Motion Settings menu: use drop-down list to change the camera number. The settings
are:
 “Detected by” provides two options to select between the software motion detection and the
on-camera motion detection. Note: some of the CBC camera models may not support motion
detection on-camera.
 “Sensitivity” is a group of controls to adjust motion detection computation:
 “Level” adjusts the inter-frame brightness change threshold that triggers
motion detection. Lower settings may cause false motion detection due to
noise.
 “Detail” adjusts the size of the detectable objects within each motion
detection zone. Lower settings may cause false motion detection due to
noise.
 “Limit” serves as a guard against false triggering due to a sudden overall
change in lighting that would trigger motion detection in a large number of
zones simultaneously. If the
number of zones activated simultaneously is
larger than “Limit”, motion detection will be blocked. This parameter
