Combining RFID access control, keypad entry, and SIP-based intercom functionality, this weatherproof unit delivers comprehensive access management in a durable, vandal-resistant package.
Key Features and Benefits

- Expansion Interfaces: RS485 and Wiegand (26 bits) input/output for integration with third-party access control systems
- SIP Intercom Integration: Makes SIP calls to Grandstream IP phones (GXP series), video phones (GXV series), and the GS Wave mobile app

Professional Access Control for Modern Facilities
The GDS3705 is engineered for organizations requiring dependable door access management with integrated communication capabilities. Whether deployed at building entrances, secure areas, or gate access points, this IP audio door system seamlessly integrates into your existing network infrastructure. The RFID reader accommodates up to 2,000 card credentials, while the illuminated metal keypad provides an alternative entry method for users without cards. Integration with Grandstream's free GDS Manager software streamlines configuration and monitoring, while SIP compatibility enables two-way communication with desk phones, video phones, or mobile devices. The relay outputs can trigger electric strikes or magnetic locks, and the alarm inputs monitor door status or integrate with external sensors. RS485 and Wiegand interfaces ensure compatibility with existing access control ecosystems.
