جهاز ميكروفون وسبيكر النداء السقفي من جراند ستريم (Grandstream) بدعم Wi-Fi/PoE

The GSC3516 is a state-of-the-art public address and two-way intercom system (SIP Intercom Speaker/Microphone) designed for sleek ceiling installation in offices, hospitals, schools, hotels, and warehouses. It functions as a central paging and audio broadcasting device for the facility, with a key feature that surpasses traditional speakers: its integrated microphones allow those in the room to respond and speak directly to the person making the call, making it a complete ceiling-mounted intercom system.

What gives the GSC3516 exceptional engineering flexibility is its dual connectivity support; it features built-in dual-band Wi-Fi for easy on-premises setups, or a wired connection via a network cable with full PoE support for simultaneous power and data. The device integrates seamlessly with UCM PBXs and IP phones, allowing you to dial the speakerphone's extension from your mobile or landline phone to initiate a call or conversation immediately.
