This document provides information about Salto offline doors and audio options for a webinar. It summarizes that Salto offline doors can increase security and safety through features like lockdown and access control while providing huge cost savings compared to fully online door systems. Offline doors take 10 times longer to install but use typically 1/3 of the hardware cost compared to online doors. A typical setup example shows using a combination of a few online doors and many offline doors can save over 50% of the total cost for access control on 30 doors compared to using all online doors.
