What is Visualisers/Document Cameras?
Many teaching rooms have document cameras which replace Over Head Projectors (OHP). They contain a movable camera which displays onto the projector. There are three types of visualisers deployed in teaching areas. Most rooms will only have modern projectors such as Samsung or Aver brands (above picture). There are also a few legacy projectors (C).
This guide explains operation of the projectors.
Why would I use Visualisers/Document Cameras with my students?
This is useful for projecting artefacts you may have (e.g. rocks, bones, small things), as well as printouts. You might also use it to diagram in real time rather than using the whiteboard.
How do I use Visualisers/Document Cameras with my students?
Part one: Crestron control panels
There are two types of control panels: button and touch screen. Make sure the systems are switched on by pressing the power button on the control panel.
To switch the room projector to the visualiser’s camera feed, select the visualiser button on the control panel.
Part two: Checking the visualiser’s power
Visualisers should be left switched on, but occasionally they might have lost power. Switch on the visualisers thusly:
Part three: Adjusting the camera
The visualiser’s camera should now be displayed on the projector. The camera will auto focus on the object under it.
Move the camera arm to point to the object you want displayed. The Aver and Samsung models have pivot heads which enable you to point the camera where you want.
