Northern California Community College System Standardizes Classroom AV Control
SAN MATEO, CA—Spanning the region between San Francisco and the Silicon Valley, the San Mateo County Community College District (SMCCD) serves more than 40,000 students. Three campuses, the College of San Mateo, Caûada College, and Skyline College, provide students a two-year education in a variety of vocational technical programs as well as studies that can be transferred to four-year colleges and universities.
Over the past few years, the SMCCD has been renovating and updating classrooms on its campuses, adding “smart classroom” technology as well as modernizing the facilities. The smart classrooms include built-in projection equipment and media centers for connection of laptop computers, document cameras, DVD players, and other media. Rooms waiting for renovation are currently using media carts.
“Our instructors rely on the media technology, but they want it to be easy to use,” said Jim Petromilli, SMCCD director of instructional technology. Petromilli’s team

“We had several criteria for choosing a control system,” Petromilli explained. “First and foremost, it had to be easy to use. Next, we wanted a consistent user experience, meaning a teacher could walk into any room and be able to activate the AV equipment, and they would be able to do it the same way every time. We wanted a setup time of three minutes or less from the time the instructor enters the room with a laptop computer. We also wanted a small form factor in the control system; we wanted it to be a low-maintenance device, and we wanted it to be easily upgradeable.”
Using these criteria, the ITS team evaluated a number of control systems and selected the SP Controls Pixie for use in the SMCCD complex. “The Pixie met all of those criteria perfectly, and it was inexpensive as well,” Petromilli noted.
The SP Controls Pixie fits in a single-gang back box and uses a Decora wall plate for trim. One Pixie can control two or more display devices, providing separate buttons for power, AV sources, and volume up/down. The unit is easily installed and set up— an infrared emitter is placed against the receiver of the projector to ensure accurate commands with each button press on the unit, and the Pixie has the ability to learn the IR commands of a remote through a few simple steps.
Pixies in SMCCD classrooms are used for projector, source, and audio control. “With the Pixie, we’re able to set up the equipment and know it won’t be inadvertently messed up by someone pressing the wrong button,” said Mike Tyler, media technician at Caûada College. “When you are dealing with remotes, there are too many things that can go wrong. One example of a problem we used to have is that people would accidentally reset the projector to the factory defaults, and since we mount the projectors upside down in the room, they would end up with an inverted image. Or they’d start playing with the focus controls and not be able to get back to where they started. With the Pixie, those controls aren’t there so the problems can’t happen.”
To further simplify installation in the classrooms, the Pixie units take advantage of the audio output of the projectors in the room. All audio goes into the projector, and audio follows video on the projectors, so when sources are switched, the proper audio comes up with the video. Audio outputs are fed into an amplifier and the Pixie is used to control volume up/down.
Between the three campuses in the SMCCD, 179 smart classrooms are currently outfitted with Pixie controllers and others are in the queue for updating. In older rooms, the Pixies are wall mounted with wires running up channels on the walls to the projector; in renovated classrooms, Pixies are mounted on the side of a media center adjacent to connection points for laptop computers.
