Viewers – All about document viewers
The viewer (also called viewer) is a very practical digital viewing tool: it allows you to display all types of documents via its camera on a computer, a TBI or a interactive screen. It is the ideal tool to accompany all your presentations, both at school and in the company.
The viewers capture sublime color video at up to 30 frames per second, in full HD quality.
On most models you can use the viewer without a computer or IWB: a simple video projector is enough.
Thanks to digital or optical autofocus, the focus is automatic, the image is always sharp.

What is a viewer?
Sometimes called viewer or viewer, the viewer is in a way the digital evolution of the overhead projector…but much more complete ! Thanks to its camera, it allows you to capture and retransmit objects, a photo, newspaper extracts, books…
Because we sometimes need non-digital resources, it is a very popular tool, especially at school, to show different objects on the big screen, and thus involve everyone.

How does it work?
Linked to a video projector or screen, the viewer broadcasts the images it captures live, in the same way as a webcam – but with a large number of additional functions. It can be added to an interactive board or a computer to directly exploit and annotate the projected image.
Its flexible head allows it to be very easily manipulated, and thus to visualize all types of documents from all angles.
Some models are equipped with a lamp or even a backlight, to be able to observe an object with more clarity.

Mobile or desktop viewer ?
Differentiated in general two types of viewers:
- Mobile viewers (preferred by schools)
- Desktop viewers (mostly used in universities and companies)
The mobile viewer
Lightweight, handy and very easy to use, the mobile viewer is totally adapted to classroom use. It allows you to view any type of document very easily, with great flexibility of use.
It is therefore a very popular tool for students in particular, who can use it wirelessly.
The desktop viewer
Designed for amphitheatres, universities and companies, the desktop viewer is more complete and accurate (zoom up to 2x higher), but also less manageable.
It is also more autonomous and has (for most models) a backlit support, in order to project an X-ray or a transparency for example.

Fluidity and image quality
The viewers are equipped with a high-resolution sensor (greater than or equal to 5M pixels), with autofocus and a very powerful optical (and/or digital) zoom.
You can film fast as well as very slow phenomena with the same fluidity.
The viewer connects to all your equipment (video projector, monitor, computer, IWB…) thanks to its many included ports: HDMI, USB, DVI, VGA, XVGA, S-Video…
Some models even connect wirelessly!
Easy to use software
The Lumens and Speechi viewers are equipped with the Ladibug software , which allows them to be fully controlled (focus, angle, zoom…) via a control panel.
It is also possible to capture and annotate the screen live, with the same interface.
Since 2007, Speechi has been offering many models of viewers (or viewers) to complete the use of its interactive solutions (IWB in particular). As with mobile interactive boards, the company favours products that are easy to use, easy to handle and easy to lend, especially for school use.
