Milestone XProtect ® Express 1.1Administrator's ManualNameSensitivityMotionKeyframe OnlyDetection intervalDetection resolutionDescriptionDetermines how much each pixel must change before it is regarded asmotion. With a high sensitivity, very little change in a pixel is requiredbefore it is regarded as motion. Areas in which motion is detected arehighlighted in green in the preview image. Select a slider position in whichonly detections you consider motion are highlighted. The more you drag theslider to the left, the more of the preview image becomes highlighted. Thisis because with a high sensitivity even the slightest change in a pixel will beregarded as motion. As an alternative to using the slider, you may specify avalue between 0 and 256 in the field next to the slider to control thesensitivity setting.Adjust the Motion slider so that motion detection is only triggered by therequired level of motion. The selected motion level is indicated by the blackvertical line in the Level bar above the sliders. The black vertical lineserves as a threshold. When motion is above (to the right of) the selectedlevel, the bar changes color from green to red, indicating a positive motiondetection.Alternatively, specify a value between 0 and 10000 in the field on the left tocontrol the motion setting.The more you drag the slider to the left, the more positive motiondetections you see because less change will be needed to trigger a positivemotion detection. The number of positive motion detections may also affectthe amount of video you record, the amount of notifications you receive,etc.If you want motion detection to take place only on keyframes of the videostream to reduce the system resources used on motion detection, selectKeyframe only.Specify how often motion detection analysis is carried out on video from thecamera. The default is every 240 milliseconds (close to once a quarter of asecond). The interval is applied regardless of your cameras' frame ratesettings.Adjusting this setting can help lower the amount of system resources usedon motion detection.Specify whether the full image or a selected percentage of the imageshould be analyzed. For example, by specifying 25%, every fourth pixel isanalyzed instead of all pixels, reducing the system resources used but alsooffering less accurate motion detection.Privacy maskingAsk yourself whether there are any areas of the camera image that must be masked from viewing. For example, ifthe camera points in a way so that it catches the window of a private building, the privacy of the residents must berespected. In that case, you can mask areas of the image by configuring the settings below.NameEnableDescriptionEnable the Privacy Masking feature.www.milestonesys.com 102 Advanced configuration
