public activityLevel : Number[read-only]

The amount of motion the camera is detecting. Values range from 0 (no motion is being detected) to 100 (a large amount of motion is being detected). The value of this property can help you determine if you need to pass a setting to Camera.setMotionLevel().

If the camera is available but is not yet being used because neither Video.attachVideo() nor NetStream.attachVideo() has been called, this property is set to -1.

If you are streaming only uncompressed local video--that is, you are not streaming the video within a NetStream object and you have not called Camera.setLoopback(true)--this property is set only if you have assigned a function to the Camera.onActivity() handler. Otherwise, it is undefined.
