     The Technology Board endorsed the following minimum specifications for equipment for smart classrooms and digital cameras at its meeting on May 4, 2000. These were determined by examining the published specifications for a range of currently available presentation devices and cameras and ascertaining which features most clearly represent desirable and affordable state-of-the-art technology.

Some classrooms would probably require lockable cabinets for securing components, while others would not. The following specifications could be adapted to meet differing needs:

• Sturdy metal cabinet designed to contain four or more discrete components
• Removable 4" casters for installations requiring component mobility
• Lockable doors for locations needing maximum security
• Built-in electric w/ surge suppressor
• Ventilation louvers in front or back of lockable cabinets

Carts for portable systems should contain and provide some security for all components, although the entire cart will inevitably remain vulnerable to damage and theft.

• Sturdy metal rolling cart capable of containing or supporting three components
• Width and length not exceeding 2’, adjustable height preferable
• Two exposed shelves, top shelf suitable for projector
• Lockable enclosure, preferably with two enclosed shelves
• 4" casters or two 4" and two 8" casters
