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
