The Noise-Cancelling IP Horn Speaker & Microphone pairs a horn-loaded driver with a Class D amplifier built directly into the enclosure, all powered over a single PoE Ethernet cable. The horn geometry concentrates sound energy for high SPL and tight directivity, delivering up to 120 dBA peak output — well suited to installations where the speaker sits at a distance from listeners and physical space for a horn-style enclosure isn't a constraint.
Because the amplifier lives in the speaker itself, there's no central amplifier rack and no traditional speaker loop to design around. Each unit is individually addressable over IP, can be grouped into zones across a LAN, WAN, or the internet, and reports its own health — network faults and electronics faults alike — to your central management platform or third-party systems via SNMP or Syslog.
The built-in microphone adds speaker-as-mic functionality: automatic volume control, self-checking diagnostics, half-duplex communication for traditional broadcast paging, and ambient listening. Combined with ONVIF support, the unit can be auto-discovered by a VMS, receive messages, and provide talkback — all without extra hardware.

Ideal Applications
- Roads & Tunnels — Built to cut through high ambient noise and control reflections that would otherwise wreck speech intelligibility in enclosed, reflective spaces.
- Truck Scales — Operators and drivers can actually hear each other over idling diesel engines, no button-pressing required.
- Industrial Sites — Rated IP66 and IK08 for dust, water, and impact resistance, with a wide -40° to 70°C operating range for demanding plant environments.
- Perimeter & Building Security — Talkback, ambient listening, and ONVIF/VMS integration make it a natural fit for asset protection and perimeter monitoring alongside existing camera systems.

Frequently Asked Questions
Do I need a central amplifier or speaker loop for this system?
No. The amplifier is built into each speaker, so there's no central amplifier unit or traditional speaker loop required. Speakers can still be grouped into zones across a network or the internet.
How is the unit powered?
Entirely over the network cable via PoE (IEEE 802.3af, Class 3, 6.49–12.95 W), eliminating the need for separate power runs.
Is it suitable for outdoor or industrial installation?
Yes. It carries an IP66 rating against dust and water ingress, an IK08 impact rating, and operates across a -40° to 70°C temperature range.
