The AtlasIED IPX Series IP-DDS is an indoor dual sided display incorporating speakers and LCD display. It can display time as well as scrolling text and leverages the VoIP communication solution to extend notifications with effective visual text alerts for high ambient noise areas or large spaces. AtlasIED IP-DDS registers as a communication endpoint directly within InformaCast, SA-Announce, and GCK advanced notification applications, supporting both visual text and audio broadcast to enhance physical security while improving day-to-day communications through advanced alerting, bell schedules, pre-recorded, scheduled announcements & intercom, while leveraging the WAN/LAN network architecture. When used within a Cisco Environment, these same IP dual sided LED displays with speakers from AtlasIED can join Cisco’s Unified Survivable Remote Site Telephony (SRST) as a supported device within SRST endpoint Architecture. Cisco’s SRST provides remote location call-processing redundancy when access to the centralized Cisco Unified Communications Manager is interrupted because of a WAN outage. The ability of LAN communication between any combination of phones and speakers is particularly critical during an emergency (which may be the actual cause of the WAN outage).
