The unit supports Power over Ethernet (PoE) for simplified installation and provides HD audio to ensure clear two‑way communication between visitors and occupants. Built for wall or surface mounting at entrances, the GSC3575 integrates with access systems to enable remote door release, visitor verification and event logging while maintaining a compact and robust form factor.

Advantages

The GSC3575 combines PoE support and HD audio to reduce wiring complexity and improve voice clarity during communication. Its access control capabilities allow remote unlocking and integration with existing security systems, while a durable enclosure suited for entrance installation provides reliable operation. The device is engineered for straightforward network integration and interoperates with standard SIP-based systems for flexible deployment with IP PBX or cloud services.

Key specifications

• Power over Ethernet (PoE) support for data and power over a single cable
• HD audio with full‑duplex two‑way communication
• Network connectivity via Ethernet with SIP support for IP PBX integration
• Wall/surface mounting form factor suitable for entrance installation
• Durable enclosure designed for continuous operation in access points

How to use

Mount the GSC3575 at the desired entrance location following the manufacturer’s mechanical and environmental guidelines. Connect the device to an Ethernet network that provides PoE power or supply compatible power separately if PoE is not available. Configure SIP account and network settings through the web interface or provisioning server to integrate the station with an IP PBX or cloud communication service. Assign access control actions and link the unit to door release hardware or access controllers as required. Test audio paths and remote unlocking functionality before placing the unit into regular operation.

Recommendations

Place the station at a height and orientation that optimizes audio pickup and visibility for visitors. Use a managed switch with PoE and VLAN support to separate voice and access control traffic for security and reliability. Regularly verify firmware updates from the manufacturer and perform periodic functional tests of audio and door release mechanisms.
