I was wondering if T4 have any recommendations regarding Visualizer models suitable for schools?

I am afraid we are prohibited from recommending equipment from individual manufacturers unless they have gone through a procurement process. Just some points you might bear in mind when making your decision on which visualizer to buy:

• What is the capture area.  We would recommend that it is capable of capturing a full A3 image.
• Has the unit built in illumination?
• Can the unit be controlled with a Remote control unit?  Not necessary, but can be useful.
• What is the Zoom range, has it auto zoom and auto focus?
• Has the unit Image freeze capability?  Can you take snapshots of the image?
• Can the unit blank or mask a portion of the image?
• How portable is the unit?
• What warranty is supplied with the unit?

These are guidelines only and individual visualizers will have other different functions & capabilities.
