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 respo...
