This Intruder Detection example shows how the Image Acquisition and Data Acquisition Toolboxes can be used together.
This program displays live video and audio data acquired from a web cam and sound card. Whenever certain motion or sound thresholds are exceeded, an alarm will sound while the video and audio data are recorded to disk for 10 seconds.
