Grandstream GDS3705 Facility Access System

The Grandstream GDS3705 is an enterprise-grade IP audio door system that provides secure access control and high-quality two-way communication for modern facilities. Unlike traditional door phones, it combines SIP-based intercom functionality with RFID authentication and keypad entry, making it an excellent solution for organizations seeking dependable, network-based access management.

The built-in RFID card reader enables convenient keyless entry for authorized personnel. Additionally, users can unlock doors remotely through compatible SIP phones, IP video phones, mobile applications, or VoIP systems, providing greater flexibility for managing visitors and deliveries.

Designed for demanding environments, the GDS3705 features a durable zinc alloy metal housing that is both weatherproof and vandal resistant. Therefore, it performs reliably at office entrances, apartment complexes, industrial facilities, schools, hospitals, and other outdoor installations.

For communication, the device includes dual microphones with advanced Acoustic Echo Cancellation (AEC) and an HD loudspeaker that delivers clear, natural conversations. As a result, visitors and staff can communicate effectively even in busy environments. The system supports SIP calls directly to IP phones, allowing receptionists or security staff to identify visitors before granting access.

Installation is straightforward thanks to Power over Ethernet (PoE) support, which supplies both power and network connectivity through a single Ethernet cable. Furthermore, the GDS3705 includes alarm inputs and outputs for integration with electric locks, exit buttons, door sensors, and existing security systems, making it suitable for complete access control deployments.

The GDS3705 also integrates with Grandstream GDS Manager software, enabling administrators to manage RFID credentials, configure devices, and simplify large-scale deployments from a centralized interface. This makes the solution ideal for businesses operating multiple entry points or multiple sites.
