a wider range of temperatures and weather conditions, realizing excellent environmental performance.
• The IP horn speaker is compatible with the following broadcasting modes:
Internal sound source
broadcasting mode
Enables broadcast of up to 20 internal sound source les by means of contact
control or Remote API (HTTP).
VMS broadcasting
mode
Enables backchannel audio broadcast from the VMS (Video management system)
software using the common protocol for IP cameras.
SIP broadcasting
mode
Enables SIP broadcasts from any voice communications device that utilizes the
SIP protocol, such as SIP or IP telephone (IP-PBX) systems.
Multicast broadcasting
mode
Allows up to 10 multicast ports to be set up, for 10 paging groups.
• Orders of priority can be set among the various broadcasting modes, meaning higher priority broadcasts can
