The GDS3705 was built for users looking for a robust audio-only facility access and security monitoring solution that can be deployed in environments of all sizes. This audio door system features dual microphones and HD loudspeakers with advanced AEC to offer intercom functionality that can support SIP calls to IP phones, and it has a built-in RFID chip reader and keypad for secure keyless or keyed entry. The GDS3705 comes equipped with a zinc alloy metal casing, making it weatherproof and vandal-resistant, and it offers alarm-in and alarm-out support for integration
with existing security devices. The GDS3705 integrates with Grandstream’s free management utility software, GDS Manager, allowing RFID card information, as well as the device itself, to be fully managed by this software.
