15W IP Horn Speaker SIP-S26H for Outdoor IP PA and Security Integration

The Tonmind SIP-S26H 15W IP Horn Speaker is designed for outdoor public address, emergency broadcasting, security linkage, and smart building audio applications. Made of durable ASA material, the speaker is suitable for harsh outdoor environments and long-term installation. With a built-in 15W amplifier, PoE power supply, and clean integrated interface design, it provides a flexible audio solution for schools, factories, hospitals, warehouses, parking areas, and outdoor security sites.

Built-in Interfaces for Flexible Outdoor Installation

SIP-S26H features a built-in Ethernet port and multiple expansion interfaces, keeping the speaker appearance clean while making installation easier. The PoE port can be directly connected to a PoE network switch, allowing both power and network transmission through one Ethernet cable without a local power supply.

The speaker provides 1 IO input channel for integrating third-party devices such as cameras, infrared curtains, smoke detectors, or alarm sensors. When an external device is triggered, SIP-S26H can activate linked alarm actions for emergency notification. It also supports 1 IO output channel, which can directly drive a siren or other external alarm device.

In addition, the DC12V output can provide power to connected external devices, reducing extra wiring and simplifying system deployment. The built-in microphone supports two-way intercom communication, and the MIC on/off switch allows users to enable or disable the microphone directly on the device.

SIP and RTP Multicast Compatibility

SIP-S26H supports standard SIP protocol and can be registered to a SIP server, SIP system, or IP PBX system. It can receive audio streams from SIP phones, IP microphones, and other SIP devices, making it suitable for voice paging, emergency calls, and public announcements.

With the built-in microphone, SIP-S26H also supports two-way intercom between a SIP phone and the IP horn speaker. This allows operators to not only make announcements but also listen and communicate with people near the speaker, which is useful for gate entrances, parking areas, factories, schools, and industrial sites.

The speaker also supports RTP Multicast, allowing audio to be broadcast to multiple IP speakers at the same time. This makes it ideal for zone paging, background music, scheduled announcements, and large-scale IP PA system deployment.

ONVIF Integration with CCTV and VMS/NVR Systems

SIP-S26H supports ONVIF, enabling integration with third-party monitoring platforms, VMS, NVR, and CCTV systems. It can be added to a security platform as an IP audio endpoint, helping users combine video surveillance and audio broadcasting in one system.

During an emergency, the operator can directly make live announcements to the speaker through the monitoring platform. The built-in microphone also allows the platform to listen to on-site audio, improving situational awareness and response efficiency.

This makes SIP-S26H suitable for applications such as perimeter security, industrial parks, campuses, warehouses, transportation areas, and public safety projects where video and audio linkage are required.

Web Configuration, Recording, and Large Built-in Storage

SIP-S26H supports flexible configuration through its web interface. Users can set SIP accounts, RTP multicast addresses, volume, alarm trigger rules, audio parameters, and other system settings according to project requirements.

The speaker also supports HTTP API, making it easier to integrate with third-party systems, alarm platforms, access control systems, and custom software. This provides more flexibility for system integrators and project developers.

With real-time voice recording support, SIP-S26H can record selected input and output audio. Its large built-in storage is designed for saving recording files and uploaded audio files, such as pre-recorded messages, alarm tones, and scheduled broadcast content.

Ideal Applications

Tonmind SIP-S26H is suitable for outdoor areas that require both public address and security linkage, such as factory entrances, industrial parks, parking lots, school campuses, warehouses, construction sites, perimeter fences, and transportation stations. It can be used for live paging, emergency announcements, alarm broadcasting, scheduled messages, and two-way communication. By integrating with SIP/IP PBX systems, ONVIF VMS/NVR platforms, alarm sensors, and external sirens, SIP-S26H helps build a reliable outdoor IP audio solution for security, notification, and daily broadcasting.
