New IP-based horn loudspeakers and amplifier module

Superior sound quality and flexible integration for video surveillance and public address applications

Video surveillance with immediate audio intervention

March 24, 2023 - The LHN-UC15L-SIP and LHN-UC15W-SIP horn loudspeakers serve as a state-of-the-art integrated audio solution for use with video surveillance 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 and large sports/entertainment venues need to maintain order and ensure that public safety or information announcements are heard quickly and clearly in indoor/outdoor areas.

In scenarios such as these, the horns can ensure real-time situational awareness with audio alerts – whether it's to stop an intruder 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 to listen to or dialog with the person(s) under surveillance.

IP-based horn loudspeakers and amplifier module

The high-output LHN-UC15L-SIP horn (for long-throw applications) and the compact LHN-UC15W-SIP horn (for wide-angle coverage) are designed to provide superior sound quality and flexible integration for video surveillance 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 AMN-P15-SIP 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 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).

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).

A complete system solution from Bosch

Bosch is a proven global leader in IP-based security cameras, video analytics and professional loudspeakers, all of which deliver an optimal combination of innovation, reliability and versatility for an array of applications. An integrated security system solution comprising Bosch IP-based horn loudspeakers with Bosch IP-based cameras can therefore offer the convenience of a single vendor with an unparalleled level of synchronized audio-visual performance.
