Tonmind SIP-S26H IP Horn Speaker: Real-Time Voice Recording and Local Storage
August 26 , 2026The Tonmind SIP-S26H 15W IP Horn Speaker with MIC is a powerful network audio solution designed for public address, two-way intercom, security communication, emergency notification and IP audio applications.
Equipped with a built-in 15W amplifier and microphone, the SIP-S26H supports two-way voice communication and high-quality network audio transmission. It is compatible with standard SIP and ONVIF protocols, making it easy to integrate with SIP servers, IP PBX systems, VMS, NVR and CCTV platforms.
The speaker also supports PoE (IEEE802.3af/at), allowing network data and power to be transmitted through a single Ethernet cable for simplified installation.
Other key functions include:
Built-in microphone for two-way intercom
Real-time voice recording
4GB or 8GB built-in storage
SIP and ONVIF compatibility
PoE power supply
RTP Multicast
Pre-recorded message broadcasting
Scheduled broadcasting
HTTP API
IO Input and IO Output
DC 12V Output
Durable waterproof ASA housing
Among these features, the real-time voice recording and local storage function significantly expands the applications of the SIP-S26H beyond traditional IP paging and broadcasting.
The SIP-S26H is available with 4GB or 8GB built-in memory, which can be used to store both uploaded media files and recorded audio.
Instead of relying entirely on an external recording server, the IP speaker can record audio directly and save the recordings locally on the device.
This makes the SIP-S26H especially useful in applications where users need to broadcast, communicate and record audio using a single network audio device.
First, make sure the SIP-S26H is connected to the network.
Enter the IP address of the SIP-S26H into a web browser and log in to the speaker's web configuration page.
Then go to:
Advanced → Record
The recording settings can be configured from this page.
Because the configuration is web-based, there is no need to install additional software simply to access the recording settings.
The SIP-S26H supports real-time recording of the audio being played through the speaker.
When Speaker Out is selected as the recording source, the system can record the audio output being broadcast from the speaker.
For example, this can include:
Live paging announcements
SIP call audio
Network broadcasting
Training or presentation audio
Other audio being played through the speaker
This is useful when organizations need to keep a record of announcements, broadcasts or other important audio communications for later review.
The SIP-S26H can also record audio captured from the MIC In source.
With its built-in microphone, the speaker can receive audio from its surrounding environment and save the recorded content directly to its internal storage.
This allows the SIP-S26H to function not only as a network speaker, but also as an audio recording endpoint for suitable applications.
For example, during a training session or classroom activity, the microphone can capture the live audio while the device stores the recording for later playback.
The combination of IP broadcasting, microphone input and local recording provides greater flexibility than a conventional one-way IP horn speaker.
Managing stored recordings is also simple.
Users can access the Record Playback section from the SIP-S26H web interface to view stored audio recordings.
Recordings can be searched according to their date and time, making it easier to find the required audio file without manually browsing through large numbers of recordings.
A typical workflow is:
Open Speaker Web Interface → Record Playback → Select Date/Time → Find Recording → Playback
This feature can be especially useful when recordings are generated regularly and users need to review audio from a specific meeting, lesson, training session or event.
Different projects may have different requirements for audio storage. For this reason, the SIP-S26H provides 4GB and 8GB memory versions.
The built-in storage can be used for:
Real-time audio recordings
Pre-recorded announcements
Alert messages
Music files
Other media files used for broadcasting
The larger local storage provides greater flexibility for projects requiring frequent recording or a larger audio file library.
By combining recording storage and media storage within the same device, the SIP-S26H can reduce dependence on additional external storage equipment in many applications.
For offices and enterprise environments, audio recording can help preserve important meeting or communication content.
The SIP-S26H can be used as part of an IP audio system for live communication while simultaneously supporting audio recording.
Users can later search for recordings according to the meeting date and time and replay relevant content when required.
This provides an integrated IP communication and recording solution for offices, meeting rooms and enterprise facilities.
Schools can use the SIP-S26H not only for paging and public address but also for applications requiring live audio recording.
For example, classroom teaching, lectures or other educational activities can be recorded and stored locally.
After the session, authorized users can access the speaker's Record Playback page and locate the required recording according to its date and time.
Combined with SIP communication, scheduled broadcasting and RTP Multicast, the recording function makes the SIP-S26H a flexible audio device for modern campus networks.
Training institutions often need to record lectures, courses and presentations for review or internal documentation.
With built-in microphone support and local storage, the SIP-S26H provides a convenient way to capture live audio without requiring a separate recording device for every application.
The recorded files can then be searched and replayed when required.
This makes the speaker suitable for:
Corporate training
Technical training centers
Educational institutions
Lecture environments
Internal employee training
Presentation and demonstration areas
Traditional horn speakers are mainly designed to broadcast audio. The Tonmind SIP-S26H adds several intelligent IP audio capabilities to this basic function.
With two-way intercom, real-time recording, local storage, SIP, ONVIF, PoE, RTP Multicast and HTTP API, the speaker can become part of a wider network communication, public address and security system.
Its standard SIP support enables integration with SIP servers and IP PBX platforms, while ONVIF compatibility allows the speaker to work with compatible video surveillance and security systems.
RTP Multicast can also be used for efficient audio distribution to multiple IP speakers, while HTTP API support provides additional possibilities for third-party system integration and automated audio triggering.
The real-time recording function makes the Tonmind SIP-S26H 15W IP Horn Speaker with MIC suitable for applications that require more than simple paging.
With 4GB or 8GB built-in storage, users can record Speaker Out or MIC In audio, store recordings locally and easily search previous recordings by date and time through the web interface.
For offices, schools, classrooms, training centers and other environments where live audio needs to be recorded and reviewed, the SIP-S26H provides a practical combination of IP broadcasting, two-way communication, recording and local storage in one device.
Together with PoE, SIP and ONVIF compatibility, RTP Multicast, pre-recorded messages, scheduling and HTTP API, the SIP-S26H offers a versatile solution for modern IP audio and communication projects.
