DS-QAZ1325G1T(C) - Network Horn Speaker 25W

The Hikvision DS-QAZ1325G1T(C) is an enterprise-grade, 25-watt intelligent active network horn speaker engineered for long-range public address (PA) broadcasting, high-decibel mass notifications, and real-time active deterrence. Housed in a heavy-duty, all-metal chassis with an extreme IP67 waterproof and dustproof rating, this high-efficiency active horn features an advanced compression driver that delivers an exceptional acoustic sensitivity of 110 dB (1 m, 1 W) and achieves a punishing maximum Sound Pressure Level (SPL) of 124 dB. Equipped with a built-in digital amplifier and an independent IP network interface, the device supports dual-voltage adaptability via Power over Ethernet (PoE 802.3af/at) or a 24 VDC physical input, entirely removing the need for external amplifiers or dedicated long-run speaker wires. It operates across a vocal-optimized 300 Hz to 8 kHz frequency response envelope and integrates an onboard industrial-grade dual-core processor with a built-in 4 GB eMMC drive (1 GB allocated for local MP3/WAV audio file storage) and an alarm input terminal. Supported by advanced acoustic algorithms (AEC, AGC, ANS, and DRC), the horn natively executes automated time-delayed schedules, real-time live paging, prioritized emergency mass alerts, direct Text-to-Speech (TTS) software commands, SIP protocol integration, and two-way audio talkback via an integrated dual-microphone array.
