Product Description

Grandstream GDS3705 IP Intercom

The Grandstream GDS3705 IP Audio Door Intercom System is ideal for application where a robust, audio-only access and security monitoring solution is required.

The GDS3705 IP Door Intercom device features dual microphones and HD loudspeaker for clear two-way communication, and supports SIP calls to IP phones. This robust audio-only intercom also features built-in RFID reader for contactless identification, as well as 12-button keypad for keyless door entry.

Built within a stylish zinc alloy metal casing, the Grandstream GDS3705 is weatherproof and vandalproof (with an IP66 rating) and supports alarm-in and alarm-out for integration with existing security systems and devices.

There is accompanying free software for the GDS3705, the GDS Manager, which allows for easy input of RFID card I.D's and external management of the device.

Fully compatible with Grandstream telephony products such as the GXP Series of IP Phones and the GXV Series of video phones, combined with the WAVE mobile application, provides an all-round access control solution from the touch of a button.
