Tonmind is pleased to introduce the new 15W IP Horn Speaker with MIC SIP-S26H, a compact and powerful network audio device designed for public address, emergency notification, security warning, two-way intercom, and outdoor broadcasting applications.

Combining a built-in 15W amplifier, microphone, PoE power supply, flexible interfaces, and SIP and ONVIF compatibility, the SIP-S26H provides an efficient audio solution for modern IP communication and security systems.

New Integrated Interface Design

The SIP-S26H features a newly designed built-in Ethernet port and integrated interfaces, creating a cleaner installation while helping protect cable connections in outdoor environments.

Available interfaces include:

• RJ45 Ethernet port

• IO Input

• IO Output

• DC 12V Output

• Reset button

• Microphone control switch

The IO Input can connect to external triggering devices, while the IO Output can be used to control indicators, alarms, or other external equipment. The DC 12V Output can also provide power for compatible peripheral devices.

Built-in Microphone for Two-Way Intercom

Unlike a traditional one-way horn speaker, the SIP-S26H is equipped with a built-in microphone, allowing users to establish two-way voice communication through SIP-based systems.

Operators can broadcast announcements through the speaker and receive audio from the installation site, making the product suitable for security monitoring, entrance communication, industrial coordination, and emergency response applications.

Its support for the OPUS 48KHz audio codec helps provide clear and natural voice communication over IP networks.

Real-Time Voice Recording and Local Storage

Another important feature of the SIP-S26H is its support for real-time voice recording. Live announcements can be recorded and saved directly to the speaker’s built-in storage.

The customizable built-in memory can store both recorded content and uploaded audio files, allowing users to create a local audio library for repeated broadcasting. This is especially useful for emergency instructions, safety reminders, warning messages, shift notifications, and scheduled announcements.

SIP and ONVIF System Integration

The SIP-S26H supports standard SIP and ONVIF protocols, enabling integration with a wide range of third-party communication and security platforms.

Through SIP, the speaker can connect with IP PBX systems, SIP servers, VoIP phones, IP paging microphones, and other SIP devices for paging and two-way intercom.

Through ONVIF, it can be integrated with VMS, NVR, IP camera, and CCTV management platforms. This allows video surveillance events and security alarms to work together with audio warnings, improving situational awareness and emergency response efficiency.

Flexible Broadcasting and Alarm Functions

The SIP-S26H supports multiple audio broadcasting and alarm management functions, including:

• RTP Multicast

• Live voice recording

• Pre-recorded message playback

• Scheduled broadcasting

• SIP paging and calling

• HTTP API control

• IO-triggered actions

RTP Multicast allows one audio stream to be transmitted to multiple Tonmind IP speakers simultaneously, making it easy to organize paging zones and large-scale announcements without creating separate SIP calls for every device.

The HTTP API also allows third-party platforms and automation systems to remotely trigger audio files or other configured actions.

Simplified Installation with PoE

With PoE support, the SIP-S26H receives both network data and electrical power through a single Ethernet cable. This eliminates the need for a separate local power supply and simplifies installation, especially in locations where access to electrical outlets is limited.

The speaker is manufactured with durable ASA material and supports an operating temperature range from -30°C to +60°C, making it suitable for demanding outdoor and industrial environments.

Designed for Diverse Applications

The Tonmind SIP-S26H can be widely used in:

• Schools and campuses

• Factories and warehouses

• Transportation facilities

• Parking areas

• Commercial buildings

• Public spaces

• Security and CCTV projects

• Emergency notification systems

Whether used as an independent SIP paging speaker or integrated into a complete IP public address and video surveillance system, the SIP-S26H provides reliable broadcasting, two-way communication, alarm integration, and flexible remote management.

With its new interface design, built-in microphone, real-time recording, local storage, PoE support, and SIP and ONVIF compatibility, the Tonmind 15W IP Horn Speaker with MIC SIP-S26H offers a versatile solution for modern IP audio and security applications.
