D-Link's latest, the Day/Night Wireless N Camera (DCS-932L) features infrared illumination to support night vision for up to 5 meters; like its predecessors, it can be controlled remotely from PCs, iPhones, iPads, Android phones, or an HDTV with a D-Link Boxee Box via the mydlink.com Website. The DCS-932L is slated to ship this spring with a street price of less than $150.

A company called TP-Link, meanwhile, is showing a surveillance camera with sophisticated, Web-based remote controls for pointing, tilting, and zooming, as well as the ability to program up to 32 preset positions and 4 "patrol tours." The TP-Link SC4171G is slated to ship by the end of March at a suggested price of $299.
