If you are not happy with the location of the mask you created, you can delete it by clicking anywhere in
the mask area. You can also cancel any edits you have made on any of the Motion Mask tabs (as long
as you have not clicked the Apply button) by clicking the Cancel button.
The Sensitivity slider control increases and decreases the sensitivity of the motion necessary to trigger
the video recording. It is a useful tool for adjusting motion recording for certain environmental or camera
signal quality factors. For example, you can set the sensitivity high (90 or 100%) if your cameras
produce a good quality video signal with little noise and are in a bright environment because camera
noise or shadows won’t cause unwanted motion recording. If you have a dark environment with poor
visibility and a poor quality video signal, setting the sensitivity low (10 or 20%) will reduce unwanted
motion recording. The slider control ranges from 1% on the left being the least sensitive to 100% on the
right being the most sensitive. To adjust the motion sensitivity, you can move the slider to the right and
left or click on the control and use the left and right arrow keys.
The Percentage slider control increases or decreases the portion of the mask area that must be filled to
trigger video recording.
Once you get the Motion Mask in the location you desire, you can set the camera to record only when
motion occurs inside the mask area by clicking the Include button. This is the system default, but you
can also block recording in the mask area by clicking the Exclude button.
You can add additional Motion Mask tabs by clicking the Add button again and repeating the process
above. To set your Motion Mask tab or tabs, click the Apply button.
To remove a Motion Mask tab, click the Edit button, click on the tab you want to remove, and then click
the Remove button. You can also remove all of the Mask tabs by clicking the Edit button and then the
Clear button.
To return to the default settings, click the Defaults button. The system will reset the Format to mpeg and
the Quality to 8. It will also clear any Motion Masks that had been created.
Some camera manufacturers have implemented cropping in their IP cameras. If you are using one of
those cameras, the Crop Window will be enabled, allowing you to crop unimportant portions of a
camera image in order to save disk space.
