Bosch has launched its new IP-based, high-output LHN-UC15L-SIP horn (for long-throw applications), and compact LHN-UC15W-SIP horn (for wide-angle coverage) as well as the AMN-P15-SIP amplifier module.

The horns are designed to provide superior sound quality and flexible integration for video security and public address applications, supporting both two-way VoIP (Voice-over-IP) communications via SIP (Session Initiation Protocol) and pre-recorded/automated messages.

The 15-watt class-D amplifier module is designed for direct connection to passive loudspeakers or via line-out to an external amplifier, serving as a bridging device to add VoIP/SIP capability to existing public address systems, increasing functionality while extending ROI. The horns are each equipped with a built-in class-D amplifier also delivering up to 15 watts and can be integrated directly into existing SIP-capable systems for use as VoIP/SIP endpoints. The horns and the amplifier module support Power over Ethernet (PoE).

Video security with immediate audio intervention

The LHN-UC15L-SIP and LHN-UC15W-SIP horns serve as a state-of-the-art integrated audio solution for use with video security systems, providing immediate audio intervention when and where it is needed most.

For example, businesses, facilities and institutions must monitor their perimeters to ensure the safety and compliance of persons on the premises and to proactively prevent trespassing, theft and vandalism. Similarly, municipalities as well as large sports and entertainment venues need to maintain order. They also need to ensure that public safety or information announcements are heard quickly and clearly in indoor and outdoor areas.

In scenarios such as these, the horns can ensure real-time situational awareness with audio alerts – whether it’s to stop intruders in their tracks on private property, or to relay a message to a group of people in a public space. In addition to pre-recorded messages that are instantly activated using camera detection with Intelligent Video Analysis (IVA), VoIP/SIP capability makes it possible to channel live speech from a central control room – either one-direction or two-way talkback utilizing the horn’s built-in condenser microphone, enabling a dialog with the person(s) in view.

Equipped with the latest technology

The horns and amplifier module offer a range of user-friendly features for flexible and cost-effective integration, including full IP for power (PoE), communication (VoIP/SIP) and control; remote configuration via a web-based GUI; Bosch Alarm Task Script Language (ATSL) support for direct camera integration; internal storage for pre-recorded messages; third-party integration via easy-to-use HTTPS REST API; GPIO for generic third-party integration; audio line-in to support live speech from other devices, such as the audio line-out of a camera; remote health/self-testing; and powerful onboard DSP (Digital Signal Processing).
