Figures from Grandstream's official product information.

The Grandstream GDS3705 in depth

Intercom and access control in one unit

The GDS3705 lets visitors call staff on SIP phones while authorised users open the door with an RFID card or keypad PIN. Its relays drive an electric lock, and alarm inputs monitor the door and exit button.

Integrates with existing systems

RS485 and 26-bit Wiegand input and output let the GDS3705 work with third-party access controllers, and GDS Manager centrally manages RFID card information and the device.

Tough enough for the front door

A zinc alloy casing rated IP66 and IK09 handles weather and tampering, with PoE making installation a single cable. Wall-surface and flush in-wall mounting are supported.
