WiFi Paging Adapter SIP-T22W Solution for Smart IP Audio Integration

Flexible Wireless IP Audio Integration for Paging, Intercom and Alarm Systems

1. Product Introduction

The Tonmind WiFi Paging Adapter SIP-T22W is a wireless IP audio gateway designed to connect traditional analog speakers with modern IP communication systems. With a built-in 15W amplifier, SIP & ONVIF support, and 2.4GHz WiFi connectivity, the T22W enables paging, emergency notification, intercom, and background music applications.

The SIP-T22W allows users to upgrade existing analog speakers into intelligent IP audio devices without complex network cabling. It is ideal for schools, factories, warehouses, offices, shopping malls, and other commercial or industrial environments requiring flexible audio communication.

2. Interface Overview and Device Connection

The SIP-T22W provides rich interfaces for audio connection, alarm integration, and external device control. All device parameters can be configured through the built-in Web Management Interface, including network settings, SIP accounts, audio parameters, and alarm functions.

● 1 × IO Input: Connects emergency buttons, sensors, door switches, or security systems to trigger prerecorded messages, SIP calls, or network commands.

● 1 × IO Output & 1 × Relay: Control external devices such as LED indicators, sirens, door locks, and automation equipment based on configured events or commands.

● 1 × MIC Input, 1 × Headset Output & 1 × Speaker Output: The MIC input supports EMC microphones for two-way intercom and live paging. The headset output connects to an analog amplifier or AUX input, while the 15W speaker output directly drives analog speakers for easy IP audio integration.

● DC 12V Input & PoE Port: DC 12V and PoE provide flexible power options for different installation environments.

● 1 × WiFi Antenna: The external antenna provides wireless network communication through 2.4GHz WiFi, offering flexible deployment where wired network connection is difficult.

3. WiFi Wireless Function

The SIP-T22W supports flexible 2.4GHz WiFi communication with two working modes: Access Point Mode and STA Mode.

In STA Mode, the T22W connects to an existing WiFi network by configuring the wireless SSID and password through the Web interface. After joining the network, the device can communicate with SIP servers, IP PBX systems, VMS platforms, and other IP devices.

In Access Point Mode, the T22W creates its own wireless network, allowing other devices to connect directly to the T22W for configuration or communication. This mode is suitable for temporary deployments, remote locations, or environments without existing WiFi infrastructure.

Users can freely switch between AP Mode and STA Mode according to different application requirements, providing greater flexibility for wireless IP audio deployment.

4. SIP and ONVIF Compatibility

SIP Protocol Integration

The SIP protocol allows the T22W to connect with Tonmind PA System Software, SIP servers and IP PBX systems. Alarms and events can be sent to the server, while IP phones, IP Paging Microphone can send control commands or make live broadcast calls through the T22W.

Through SIP integration, the T22W supports two-way communication, remote paging, emergency broadcasting, RTP Multicast, and seamless connection with existing VoIP systems.

ONVIF Protocol Integration

The ONVIF protocol enables the T22W to integrate with professional CCTV systems. It can connect alarm devices, IP cameras, VMS, and NVR platforms into one unified security system.

Through ONVIF integration, users can monitor device status, send control commands, and respond to security events through a centralized management platform, combining video surveillance and IP audio communication efficiently.

5. Conclusion

The Tonmind WiFi Paging Adapter SIP-T22W combines wireless connectivity, IP audio conversion, SIP communication, and ONVIF integration into a compact and flexible solution.

With its powerful interfaces, built-in amplifier, WiFi capability, and compatibility with third-party systems, the T22W provides an efficient way to upgrade traditional analog speakers into intelligent IP audio systems for paging, security, and communication applications.
