motionLevel (Camera.motionLevel property) -- Flash CS3

A numeric value that specifies the amount of motion required to invoke Camera.onActivity(true). Acceptable values range from 0 to 100. The default value is 50.

Video can be displayed regardless of the value of the motionLevel property. For more information, see Camera.setMotionLevel().

Example

The following example continually detects the motion level of a camera feed. Create a new video instance by selecting New Video from the Library options menu. Add an instance to the Stage and give it the instance name my_video. Add a Label component instance to the Stage and give it the instance name motionLevel_lbl, a NumericStepper with the instance name motionLevel_nstep, and a ProgressBar with the instance name motion_pb. Then add the following ActionScript to Frame 1 of the Timeline:

var my_cam:Camera = Camera.get();
var my_video:Video;
my_video.attachVideo(my_cam);

// configure the ProgressBar component instance
var motion_pb:mx.controls.ProgressBar;
motion_pb.mode = "manual";
motion_pb.label = "Motion: %3%%";

var motionLevel_lbl:mx.controls.Label;
// configure the NumericStepper component instance
var motionLevel_nstep:mx.controls.NumericStepper;
motionLevel_nstep.minimum = 0;
motionLevel_nstep.maximum = 100;
motionLevel_nstep.stepSize = 5;
motionLevel_nstep.value = my_cam.motionLevel;

// Continuously update the progress of the ProgressBar component instance to the activityLevel 
// of the current Camera instance, which is defined in my_cam 
this.onEnterFrame = function() {
    motion_pb.setProgress(my_cam.activityLevel, 100);
};

// When the level of activity goes above or below the number defined in Camera.motionLevel, 
// trigger the onActivity event handler. 
my_cam.onActivity = function(isActive:Boolean) {
    // If isActive equals true, set the themeColor variable to "haloGreen". 
    // Otherwise set the themeColor to "haloOrange". 
    var themeColor:String = (isActive) ? "haloGreen" : "haloOrange";
    motion_pb.setStyle("themeColor", themeColor);
};

function changeMotionLevel() {
    // Set the motionLevel property for my_cam Camera instance to the value of the NumericStepper 
    // component instance. Maintain the current motionTimeOut value of the my_cam Camera instance. 
    my_cam.setMotionLevel(motionLevel_nstep.value, my_cam.motionTimeOut);
}
motionLevel_nstep.addEventListener("change", changeMotionLevel);
