Polycom intros HDX 7000 HD video conferencing solutions
Although Polycom just got around to shipping its HDX 4000 / 8000 HD video conferencing systems last month, you won’t catch this firm resting on its laurels — oh no. Instead, it’s pushing out an entirely new series in its HD video portfolio, the HDX 7000.
This one, which caters to small and medium-sized conference rooms, features 22kHz StereoSurround for “natural voice clarity,” Lost Packet Recovery (LPR) technology, 720p video support, a 16:9 EagleEye HD camera and the ability to adjust bandwidth for content. You’ll also find an RS-232 control port along with DVI, USB 2.0 and a number of audio inputs and outputs. Supposedly, to-be owners can expect the HDX 7002 to land in March for $9,499, while the HDX 7001 (SD version) lures in the bargain hunters at $7,999.

William Landay, head of the Office of Naval Research, witnessed the shot via a live video feed at the Naval Surface Warfare Center in Dahlgren. The gun was launched from a control center after approximately four minutes of charging the electromagnetic rails. After the charge, the gun fired and witnesses saw a quick burst of flame as the projectile, traveling at 2,500 meters per second, or Mach 7, hit its target.
