Kramer Introduces a New Wall Plate Switcher/Transmitter

Introducing WP−577VH: The New Wall Plate Switcher Transmitter

Kramer Introduces a New Wall Plate Switcher/Transmitter
 

Kramer Electronics is pleased to introduce the WP−577VH, a 2−gang Decora wall plate CATx switcher/transmitter for HDMI, VGA and stereo audio with support for RS−232 data and control.

The WP−577VH has auto switching capability. It will automatically switch to either the last connected input, or a selected priority input, and transmits the signals to a compatible DGKat twisted pair receiver (such as the TP−578H). These automatic switching features make the WP−577VH an ideal solution for a Bring−Your−Own−Device environment such as boardrooms, hotel rooms and hospitality venues. The use of Kramer DGKat technology allows for easy installation of the WP−577VH and signals can travel up to 70m (230ft) at 1080p60 over CATx cabling. The WP−577VH also has automatic analog audio detection and embedding. Stereo audio can be embedded into the signal (either HDMI or VGA) or transmitted by itself without video.

The WP−577VH can be powered via a single connection to either the transmitter or receiver through Kramer’s Power Connect Plus™ system. K−Link™ compatibilitygives the unit the flexibility to either control remote devices, or be controlled by Kramer Protocol 3000, and to send data to external RS−232 devices.

The WP−577VH provides signal reclocking and equalization, is HDTV compatible and HDCP compliant, and offers a maximum date rate of 4.95Gbps (1.65Gbps per graphic channel). The unit also passes EDID from the display to the source.

The WP−577VH is in stock and available from Kramer offices around the world.

Interactive Projectors

Interactive White Boards has been around in the market for quite sometime now. Despite the varying technologies employed by the different manufacturers, they share something in common, the use of a projector.

Projection application has moved beyond simple presentation on a white screen. The demanding environment in today’s world needed something more. Interactive White Board was one of the many ideas that helps bring classrooms/ meetings alive; making the presentation livelier and getting the audience involved easily. And now, projector manufacturers are eyeing a piece of this newfound demand for interactivity.

Interactive Projectors incorporated an additional ‘Transmitter’ and ‘Receiver’ device to allow actions on the screen to be transferred into the connecting computer. Regardless of the technology used, the principals are pretty much the same, to compete with Interactive White Boards.

Some of the pros and cons between the two:

Function(s) Interactive White Board Interactive Projector (Short Throw)
Cost Cost of Projector + Cost of Board + Cost of Projector Installation + Cost of Board Installation Cost of Projector + Installation only
Projection Surface Must be on the board Can be only any hard and smooth enough surface
Glare, Hot Spot & Shadow Will need to use an ultra-Short Throw Projector to minimize these effects, which means additional cost Effects reduced with Ultra-Short Throw capabilities
Image Size Image size is fixed Can adjust big/ small image size by changing projection distance
Sensitivity Dedicated sensors behind the board will have excellent response Subject to the technology of the “Transmitter/ Receiver” device, might have slight lag depending on the setup conditions
Software Most Interactive White Boards do provide optional Interactive Software for instant application No full-fledge interactive software, but able to work with 3rd party Interactive Software

Although the technology is available and choice between the two will be based on individual’s requirements, it is important to understand that technology is nothing when the users are not properly trained to use them.

Most users will find it daunting to do an interactive setup and scrambling to understand the buttons and logos to use the interactivity features properly. Hence without the right training, most, if not all technology will be nothing but an additional piece of under-utilized hardware.
