Have you ever wondered how you could set your webcam up as a security
camera and have the images sent to you somewhere else? Maybe you wanted
motion detection or noise detection to turn it on automatically? Or
maybe that's just us, and we're a little paranoid. Regardless,
Periscope is a tool that lets you do all of those things with your webcam, and more.

You can trigger it to start recording in several ways: motion
detection, noise detection, via Apple Remote, or with a timer. Once
it's on, it'll capture images and save them to disc or send them to a
few other places for review. It works with Flickr, e-mail, FTP, iPhoto,
and the now-obsolete .mac (presumably an upcoming version will support
MobileMe). You can also time-stamp or add your own logo automatically
to your pictures.
Even if you're not interested in the
security applications of Periscope, you might find it useful for making
time-lapse videos. With its ability to capture images at intervals, you
could theoretically capture your entire day at your desk if you had the
disk space. Although we tested it with a built-in iSight, Periscope
should work with other webcams.
