The iSight is a webcam made by Apple Computer. It is a FireWire camera that can be mounted on any current Apple laptop, all-in-one desktop, and display. The iSight was designed for iChat AV, Apple's video-conferencing client. iMovie 4 can be used to capture video from the device, which is also the recommended camera for use with Freeverse Software's ToySight game collection.

Some advocates claim the iSight has superior colour quality and striking industrial design. The 1/4-inch color CCD sensor has a 640x480 VGA resolution. Apple calls iSight's three-part F/2.8 lens with two aspherical elements custom-designed. It features auto-focusing from 50mm up and autoexposure and can capture video at 30 frames per second in 24-bit color and use a variety of shutter speeds. All iSights include internal microphones, which, Apple advertises, feature dual-element noise-suppression.

While the iSight is compatible with both Mac OS X and Windows computers, the internal microphones will only operate on a Mac with the iChat AV software installed.

The iSight uses an included FireWire cable for audio, video, and power. Three camera stands, a carrying case, and a FireWire cable adapter are also included.

Apple introduced the iSight at 2003's Worldwide Developers Conference.
