MildMannered Inds has released a public beta of Iris, a freeware application for Mac OS that allows you to do more things with an iSight based Camera.

Here are some of the key features of this application:

-Take Snapshots
-Make Movies
-Record TimeLapse Movies
-Detect moving objects with Motion Detection and Email Alerting
-Broadcast video over the web, with Iris’s built in WebCam
-Browse snapshots and movies in Iris’s built-in Gallery. Send them by email, upload them to Flickr, or export them to view on your iPod, Apple TV, or iPhone.

The motion detection feature takes a snapshot of an object when motion is detected and sends an email to the owner with details.

Download Iris for Mac OS here. Iris is a Universal Binary, and will run on PowerPC or Intel based Macs.
