Optimized for Video Conferencing
Special Surface for Transparencies
All WolfVision Visualizers have a special crystalline white working surface for perfect
reproduction of transparencies. The quality of a transparency on this surface is even
better than with a bottom light, because there is more contrast and the colors are not
"washed out".
The whole working surface has the same even color thus providing the perfect
background for transparencies and other objects.
For x-rays or oversized slides, external lightboxes are available.
WolfVision's camera electronics produce a very strong and stable picture,
which is very important when a Visualizer is used as a document camera for
videoconferencing systems.
The even lighting, smooth auto iris and perfect focus are very important
features, enabling video conferencing systems to digitize and transfer the
picture from a WolfVision Visualizer much faster than pictures from other
document cameras. Furthermore there is no blinding stray light from a
WolfVision Visualizer, which could disturb the auto iris of the room camera.
Of course these features are equally important for live image presentations
with a data projector and for other Visualizer applications.
Due to the "Image Flip" feature the Visualizers can also be used as an
additional room camera of a videoconferencing system.

The VZ-8plus has PAL/NTSC video outputs for video conferencing systems
without data input. Plus it also supplies the proper signal for modern
widescreen videoconferencing systems.
The user has the opportunity to store 9 images and recall them by just
pressing one of the numerical keys on the infrared remote control.
By pressing the "All" key, a split image with all 9 pictures of the memory can be
displayed, enabling easy selection. The 9 pictures in the memory can also be
downloaded to a PC via USB.
The Visualizer is equipped with a battery backup, so pictures remain in the
memory for 1-4 weeks even when the power is disconnected.

The VZ-8light offers a 1 image freeze function, instead of the 9 picture
memory.

WolfVision Visualizers offer many possibilities to improve the readability of text.
With the "Text Enhancer" function, the outstanding contrast of the picture is
improved even more with colors only slightly darker than before.
Dark text on a bright background can sometimes be easier to read if the
Visualizer is switched to "Negative" or "Negative/Blue".
For special applications (like analyzing x-rays), the image can also be switched
to Black and White.

High Speed Autofocus
The continuously working autofocus recognizes every object quickly and precisely. As
a result, the presenter never needs to worry about focusing. The high speed of the
autofocus is due to a special WolfVision software, which is analyzing 30 frames per
second.
For special objects, a manual focus is also available.
