1 Product Overview
The CyberData SIP-enabled V2 Speaker is a Power-over-Ethernet (PoE 802.3af) and Voice-over-IP
(VoIP) public address two-way loudspeaker that easily connects into existing local area networks
with a single CAT5 cable connection. The speaker is compatible with most SIP-based IP PBX. In a
non-SIP environment, the speaker is capable of broadcasting audio through multicast. Its small
footprint and low height allows the speaker to be discretely mounted almost anywhere.
The CyberData V2 Speaker is an innovative addition to our portfolio of paging/notification
products. As an example, in an open-room setting, the CyberData V2 Speaker with its adaptive full-
duplex voice operation allows for clear two-way communication during event notifications.
Note Prior to installation, create a plan for the locations of your speakers.
General Alert
Consult local building and electrical code requirements prior to installation.
