Grandstream GDS3705 IP Audio Door System – SIP Intercom with RFID, PoE & Weatherproof Design

Description

The Grandstream GDS3705 IP Audio Door System is a robust and reliable access control solution designed for secure facility entry and audio-based communication. It is ideal for offices, residential buildings, warehouses, schools, and industrial environments that require controlled access and real-time communication.

Unlike traditional door entry systems, the GDS3705 is a SIP-based IP intercom, allowing seamless integration with VoIP networks, IP phones, mobile apps, and IP PBX systems. It enables users to initiate and receive calls directly from the door station, providing efficient visitor management and remote access control.

The device features HD audio with dual microphones and a built-in loudspeaker, supported by advanced acoustic echo cancellation (AEC), ensuring clear two-way communication even in noisy environments.

For secure entry, the GDS3705 includes a built-in RFID chip reader and keypad, allowing both keyless card access and PIN-based authentication. This makes it suitable for modern access control systems without the need for traditional keys.

Built with a zinc alloy metal casing, the device is weatherproof and vandal-resistant, ensuring durability in outdoor installations and harsh environmental conditions.

The GDS3705 supports Power over Ethernet (PoE), simplifying installation by delivering both power and network connectivity through a single cable.

It also offers alarm-in and alarm-out interfaces, enabling integration with door sensors, exit buttons, electric locks, and other security systems for a complete access control solution.

With support for Grandstream’s GDS Manager software, administrators can centrally manage RFID cards, monitor devices, and configure settings across multiple sites.

The Grandstream GDS3705 IP Audio Door System is a cost-effective and scalable solution for organizations that need secure, durable, and easy-to-integrate access control with SIP-based communication capabilities.
