A new security system in Extron’s VoiceLift microphone system gives educators many of the same capabilities, but with a key difference: Schools don’t have to use cameras made by a specific manufacturer, Extron said.
Crestron’s FreeSpeech wireless microphone system also includes a panic button, which sends an emergency alert to the company’s RoomView AV controller software—but it adds another innovation designed to save instructors from potential embarrassment.
The microphone uses both radio frequency (RF) and infrared (IR) technology to connect with a receiver. The sound waves travel via RF technology, but the IR connection exists so that if an instructor leaves the room—say, to use the bathroom—but he or she forgets to turn off the mic, the device no longer will broadcast.
