The Green Slim Projector was only 1.7 inches thick, making it among the market’s most portable projectors. But its slim form factor also was somewhat limiting. At this year’s InfoComm, Casio launched two new series of lampless projectors—a Pro and a Short Throw series—that “remove the shackles of the slim form factor,” said a Casio representative.

Casio’s Short Throw lampless projectors allow a 60-inch image to be projected from less than three feet from the screen. They can display 3D content and include an optional pen and software for turning any surface into an interactive workspace, allowing users to annotate and save projected content.

The company’s Pro series of lampless projectors also are 3D-ready. They are networkable, put out 10 watts of sound, and offer up to 3,500 lumens of brightness, Casio said.

For schools that already own lamp-based projectors, Extron Electronics announced that its PoleVault and WallVault AV switching systems include an automatic shut-off feature that can save power and extend a projector’s lamp life.

If the systems determine there has been no action taken within a certain amount of time (as set by the user), they will power down the projector automatically, Extron said.

The PoleVault system is designed for classrooms with a ceiling-mounted projector, and the WallVault system is designed for rooms with a wall-mounted projector. Both include complete, centralized AV switching with audio amplification, as well as network connectivity for web-based monitoring and problem resolution.

Crestron’s RoomView AV scheduling and control software, which runs on Windows-based servers, also enables schools to be more energy-efficient.

Designed to give users control of their AV and electronics systems over an IP network, RoomView allows administrators and support staff to manage AV resources, perform remote system diagnostics, track the usage of projector lamps, log network activity, and automate tasks, all through a single browser interface.

Users can see whether projectors, lights, TVs, and other devices are on or off, and they can schedule these systems to turn off automatically at certain times of the day. Users also can preset the thermostat levels of various rooms to correspond to when the rooms will be in use, thereby maximizing energy efficiency.
