Key Features of the Grandstream GDS3702 IP Audio Door Bell System
π High-Definition Two-Way Audio Communication
At the core of the Grandstream GDS3702 is its 2-watt HD loudspeaker with excellent output clarity. With a powerful speaker capable of delivering audio up to 3 meters, and a sensitive built-in microphone supporting clear voice input up to 1.5 meters, the system ensures smooth, reliable communication at the door.
Whether it’s for greeting visitors, communicating with delivery personnel, or verifying an identity, the HD audio and echo cancellation features allow for a crystal-clear conversation every time.
π Secure Access Control with Relay and Alarm Integration
Security is a key aspect of the GDS3702, and it shines in this area. This audio doorbell system includes:
- Two alarm inputs β ideal for door sensors, motion detectors, or exit buttons
- Two relay outputs β to control electric door locks, gates, or alarm systems
This gives you full control over who enters and when. With proper configuration, it can easily serve as a complete standalone access control system or be integrated with a broader building security network.
π§ Built for Outdoor Durability β IP66 & IK10 Rated
The GDS3702 is housed in a metal enclosure thatβs both IP66-rated waterproof and IK10 vandal-resistant, making it extremely durable and ideal for outdoor or semi-outdoor installations. It can withstand rain, dust, heat, and even deliberate tampering attempts.
Whether you’re installing it at the main entrance, gate, or exposed corridors, you can be confident in long-lasting performance and protection.
β‘ Simplified Installation with PoE Support
Say goodbye to multiple cables. The Grandstream GDS3702 supports Power over Ethernet (PoE), which allows you to power the device and provide network connectivity using a single Ethernet cable. This makes installation cleaner, faster, and more efficient.
It supports IEEE 802.3af Class 3, ensuring compatibility with most standard PoE switches or injectors.
π‘ Flexible Networking and SIP Integration
As an SIP-enabled device, the GDS3702 integrates smoothly with a wide range of VoIP systems and IP phones. Whether youβre using a Grandstream phone system or a third-party IP-PBX, the GDS3702 supports SIP calls, intercom features, and remote door unlocking β even from mobile devices using compatible apps.
This makes it ideal for:
- Office environments
- Smart home integrations
- Commercial properties with remote receptionist systems
- Multi-tenant apartment buildings

To ensure optimal call quality over varying network conditions, the Grandstream GDS3702 supports a wide range of voice codecs, including:
- G.711 ΞΌ-law and A-law
- G.722 (wideband audio)
This flexibility allows for efficient bandwidth usage while still delivering superior sound performance.
π§° Versatile Mounting Options
Installation is made even more flexible with on-wall and in-wall mounting options. This gives system integrators and installers the freedom to choose the best mounting style based on space, aesthetic preferences, and user convenience. (Please note: the in-wall mounting kit is sold separately.)
