Tonmind Launches New 15W IP Horn Speaker with Built-in Microphone SIP-S26H
Aug 06, 2026Combining 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.
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.
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.
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.
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.
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.
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.
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.
