In 2002, we reported on how designers built wireless Internet (WI) cameras using standard CMOS imagers coupled with 802.11b-based wireless networking. One such product was the D-Link Air from D-Link Systems (Irvine, CA; www.dlink.com), a WI camera primarily targeted at surveillance applications. While these cameras still fill a need, their applications are limited since their true frame rate (and resolution) depends on the level of image compression, resolution, and bandwidth performance.
