Wireless Video Presentation System II
Wi-Fi VGA Presentation System
December 6, 2010
If you have a frequently-used conference room, you already know how much of a hassle connections can be. Every computer system is different, and switching from one source to another can be frustrating. Enter the Wireless Video Presentation System II from Black Box, a wireless video system capable of sending computer video signals over a simple wireless network.
The idea is simple: connect your computer to the Black Box WVPS II's wireless network, install their software, and your computer streams video data over the wireless network. In practice, the WVPS II has quite a few tricks aside from just simple projection. It also has a few flaws that one might not anticipate. But all in all, for a high-volume shared conference space, it's a good investment at $449 direct from Black Box or as low as $380 from licensed resellers.
What the WVPS II does, in its simplest form, is removes the need to connect audio and video cables between projector and computer. It also allows you to connect more than one projector at a time; up to four can be displayed in split-screen, with more participants connected and waiting in the wings. Browser-based conference management software allows the meeting host to control whose turn it is.
The WVPS II is ideal for a conference room that is shared by a large number of people, especially if some of those people come from outside your company or use non-standard laptops. Since laptops these days use a wide variety of video connections ranging from VGA to DVI and HDMI as well as all manner of proprietary connectors, this is not an uncommon situation.
The WVPS II can be attached to any projector with a VGA port, but it can only output three resolutions: 1024x768, 1280x768, or 800x600. For the best visual experience, use a projector with one of these native resolutions. The presenters' laptops must be connected to the WVPS II's own wireless network during use, so anyone relying on WiFi for their Internet connection will need to make alternate arrangements. Luckily, connecting the WVPS II to your workplace's wired network allows the unit to serve as a wireless bridge. If your presenters need Internet connectivity, make sure to run an RJ45/ethernet cable to the WVPS II unit.
