Unfortunately, school campuses aren't necessarily the safest places on earth, but the RAVENAlert Keychain hopes to change this sad fact. A campus emergency alert, it uses a proprietary one-way wireless network to broadcast news 15 to 20 seconds after it has been dispatched from campus security.

A convenient accessory, the RAVENAlert Keychain clips easily to backpacks, clothes and more. Created by Intelliguard, it emits a loud, audible alert and vibrates upon receipt of an emergency message.
