Camera class

Example

In the following example, the ProgressBar instance changes its halo theme color when the
activity level falls below the motion level. You can set the number of seconds for the

motionTimeout

property using a NumericStepper instance. 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

motionTimeOut_nstep

, and a ProgressBar with the instance name

motion_pb

. Then add the

following ActionScript to Frame 1 of the Timeline:

var motionLevel_lbl:mx.controls.Label;
var motion_pb:mx.controls.ProgressBar;
var motionTimeOut_nstep:mx.controls.NumericStepper;
var my_cam:Camera = Camera.get();
var my_video:Video;
my_video.attachVideo(my_cam);

this.onEnterFrame = function() {
motionLevel_lbl.text = "activityLevel: "+my_cam.activityLevel;
};

motion_pb.indeterminate = true;
my_cam.onActivity = function(isActive:Boolean) {
if (isActive) {
motion_pb.setStyle("themeColor", "haloGreen");
motion_pb.label = "Motion is above "+my_cam.motionLevel;
} else {
motion_pb.setStyle("themeColor", "haloOrange");
motion_pb.label = "Motion is below "+my_cam.motionLevel;
}
};
function changeMotionTimeOut() {
my_cam.setMotionLevel(my_cam.motionLevel, motionTimeOut_nstep.value/

1000);

}
motionTimeOut_nstep.addEventListener("change", changeMotionTimeOut);
motionTimeOut_nstep.value = my_cam.motionTimeOut/1000;
