AtlasIED IHVP+ is a vandal proof, weather resistant, wall mount IP speaker. It leverages VoIP communication to extend tele-presence with enhanced audio for environments where network-wide communication is desired and high-output speakers are required to overcome high ambient noise and or large spaces. The speaker grills are vandal and weather resistant. Manufactured of cast aluminum alloy, the grills provide security and durability in indoor and outdoor applications. AtlasIED IHVP+ registers as a communication endpoint directly within InformaCast, GCK, and SA-Announce Advanced Notification applications, supporting audio broadcast to enhance physical security while improving day-to-day communications through advanced alerting, bell schedules, pre-recorded and scheduled announcements, while leveraging the WAN/LAN Network Architecture. When used within a Cisco Environment, the IHVP+ speakers can join Cisco's Unified Survivable Remote Site Telephony (SRST) as a supported device. 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). Where 3rd party notification applications are not required, the IHVP+ vandal proof, weather resistant, wall mount IP can register as SIP devices directly to a SIP server or VoIP Communications Manager for critical alerts and public address applications.
