FAQs
What does the 126 dBA output mean for coverage?
126 dBA is extremely loud—suitable for large indoor venues and outdoor spaces. It ensures announcements are heard clearly across expansive areas like warehouses, parks, and sports facilities, even with background noise.
Can the GSC3518HS be used outdoors?
Yes. The IP66 rating provides complete protection against dust and water ingress, and the stainless steel housing resists corrosion from weather exposure, making it ideal for playgrounds, parks, and outdoor industrial sites.
How does PoE++ input and PoE+ output work?
The unit receives power via PoE++ (higher power standard) and can output PoE+ to cascade additional devices. This eliminates the need for separate power supplies and simplifies network cabling.
Does it integrate with existing VoIP systems?
Yes. The GSC3518HS supports both SIP and multicast protocols, allowing seamless integration into most modern VoIP phone systems and network infrastructure.
What is the AI noise reduction feature?
AI noise reduction processes audio from the three built-in microphones to filter background noise and ensure clear two-way communication, even in loud environments like factories or busy public spaces.
Can announcements be automated?
Yes. The built-in text-to-speech capability enables automated announcements for routine messages, reducing the need for manual broadcasting.
What is the warranty period?
The GSC3518HS comes with a 24-month manufacturer warranty.
