Coexist In Harmony
Managing remote teaching and learning from a classroom can be challenging. On Air Warning! will let everyone in class know that the remote students and/or guest speaker can hear and/or see them.
Know if they can see you!
MuteBar Software by On Air Warning! lets you adjust the color
and brightness of each indicator light.
Our unique Clip Mount works with any laptop and most monitors. Just slide the On Air Warning! device in and clip it to your screen for maximum visibility.
Sometimes the most visible location is on a desk, file cabinet or shelf. It is super easy to slide the On Air Warning! device into this stable Desk Mount.
On Air Warning! can mount to almost any monitor by using either the Clip Mount or by using hook and loop fasteners directly from the monitor to the On Air Warning! bottom rail.
Sometimes On Air Warning! needs to be front and center so everyone can see it, that’s when the threaded bottom on the Clip Mount comes in handy!
If you need On Air Warning! mounted on your wall, just select the Vertical option at checkout.
Working hands-on with On Air Warning has all of our staff wishing they had one.
