IP Horn Speaker

Add a strong voice to your IP System

Plug & Sound: Based on open standards, the IP-A1SC15 IP Horn Speaker plugs right into standard IP networks and can be easily integrated with your VMS or SIP-based system. The IP horn speaker broadcasts crystal clear pre-recorded voice messages, manually or automatically triggered by IP cameras, image sensing or motion detection video systems, or live speech announcements via VoIP (Voice over IP) / SIP phone or video management systems.

High sound pressure level: The integration of the IP horn speaker via PoE+ enables the integrated amplifier to broadcast excellent sound quality at a very high sound pressure level over long distances.

Robust weather resistant housing: The IP-A1SC15 combines the TOA proven robust construction with the latest IP technology. Its weatherproof enclosure is perfectly suited for outdoor applications.

Simple to install wherever you need a strong voice: A single standard network cable provides both power and connectivity with your network.

Easy to customize over API (Application Programming Interface): Adapt the individual volume to the environmental noise level and optimize it to time of day, distance, and degree of emergency.

Flexible group paging: The IP-A1SC15 IP Horn Speaker can be addressed via multicast enabling audio paging into groups of IP devices simultaneously.

Application examples:
VMS calls and paging into outdoor areas as construction sites, company or private properties, or parking spaces, as well as alert/every-day paging into outdoor areas of public buildings as schoolyards, hospitals or office buildings. The IP-A1SC15 horn speaker can be integrated into security poles.
