Masking
Use this option to create masks that will cause motion in user-specified image areas to be ignored (Motion Mask), or prevent user-specified regions of the image from being seen (Blockout Mask) for the selected camera during alarm and surveillance activities.Note: When switching between the Motion Mask and Blockout Mask tabs, you may notice a difference in the size or resolution of the displayed Camera view. The Blockout Mask shows the entire field of view of the camera, while the Motion Mask shows the current cropped area of the Camera view. If you have limited the view of the camera by zooming in on the displayed image (through the device web interface or the NetBotz Advanced View application), the Motion Mask tab will show only the cropped area.
Motion Mask
Use this tab to configure the camera's motion sensor to ignore movement that is detected in specified regions of the image capture.Note
A motion mask causes the camera to ignore any detected motion in the masked area. If detected motion would normally cause a clip to be generated, the motion mask prevents any action from being taken. These masks are useful if you want to restrict the camera to movement only in a certain area: for example, monitoring an entryway next to a busy corridor. Using a motion mask, you can block off the corridor, so that only motion through the entryway causes a clip to be generated.

| Drawing Mode |
Select the Drawing Mode. Mask: dragging the mouse across the displayed Camera view draws a green masking rectangle. After you release the mouse button, the masking rectangle turns light blue. Any motion that takes place behind the blue rectangle will not trigger a clip. Unmask: dragging the mouse across the displayed Camera view draws a purple rectangle. After you release the mouse button, the rectangle disappears, along with any portion of a masking rectangle that intersects the purple rectangle. You can flip back and forth between modes as many times as you like until the motion mask is defined to your liking. Once you are finished, click Apply to save your changes. If you want to remove the current mask, click Revert Masks. This does not affect masks that you have already saved with the Apply button. If you want to remove an applied mask, use the Unmask mode. |
| Area of Motion |
Use this setting to specify how large an area of the image must change (as determined by the Sensitivity value) before the changed image is considered movement. A lower Area of Motion value indicates a smaller area and therefore a smaller amount of movement is required to flag a change. |
| Sensitivity |
Use this setting to specify how much change in a portion of the image will be tolerated before the changed image is considered movement. A lower Sensitivity value indicates less tolerance for change between images. More subtle movements will be marked as a change. |
| Enable Camera Motion | Select to enable the camera motion sensor. |
| Show Motion Outline | Select to have a dotted-line outline surround any region of a captured image that is determined to be indicative of motion. |
Blockout Mask
Use this tab to configure a selected camera so that specified areas of the image cannot be seen, when that camera is monitored by a NetBotz Appliance that has the Premium Software Module.| Element | Description |

| Drawing Mode |
Select the Drawing Mode. Mask: drag the mouse across the displayed Camera view to draw a green masking rectangle. After you release the mouse button, the masking rectangle turns light blue. When the surveillance feed is viewed, the masked area will be covered with a light grey rectangle. Any motion that takes place behind the gray rectangle will not trigger a clip. Unmask: drag the mouse across the displayed Camera view to draw a purple rectangle. After you release the mouse button, the rectangle disappears, along with any portion of a masking rectangle that intersects the purple rectangle. You can flip back and forth between modes as many times as you like until the motion mask is defined to your liking. Once you are finished, click Apply to save your changes. If you want to remove the current mask, click Revert Masks. This does not affect masks that you have already saved with the Apply button. If you want to remove an applied mask, use the Unmask mode. |
