LOUD AND CLEAR
Emergency communications cannot include bad audio. It should incorporate solutions that are intelligible in even the most chal- lenging circumstances that enable security teams to deliver clear instructions with intelligible voice and audio whenever the need arises and to improve the quality of assistance provided by secu- rity guards and control rooms.
In today’s ever-changing and ever increasing and complicated risk environment, the importance of high-quality, clear audio can- not be understated. It is purchase a communications system and send emergency communications if the audible announcements and messages cannot be heard, or understood. It is time to stop accepting bad audio, and instead, embrace a
solution that offers audio and voice technology
that allows people to hear, be heard, and be un-
derstood in every situation.
