Grandstream GSC3575 7-inch Android Intercom Indoor Station, Black, Wi-Fi 6

Overview

The Grandstream GSC3575 is a black indoor screen (intercom indoor station) that runs Android, with a 7-inch touchscreen for answering door stations, seeing the visitor and releasing the door. It also arms local alarm zones from its own inputs and can switch to a meeting room panel mode. It suits apartments, offices, hotels and shopping centres that need an indoor screen for door calls, and meeting rooms that need a booking panel. The GSC3574 is the same station in the other colour.

Is it right for you?

• Choose it as the indoor half of a Grandstream intercom, paired with the GSC3560 or GSC3565 outdoor intercoms, and as a panel for a building with several doors and cameras: it links up to 50 door stations and 32 IP cameras.
• 8 alarm inputs and 2 relays suit an apartment or office that wants door sensors, panic buttons and two locks or lights handled from one screen; the earlier Linux-based GSC3570 is the simpler option.
• Meeting room booking mode needs a Grandstream UCM with Wave.
• Indoor use only, within 0 to 40 °C.

What else you need

• A door station to answer, such as the Grandstream GSC3560 or GSC3565 outdoor intercom.
• Power: a PoE switch port (802.3af Class 3) or a 12 V DC 1.5 A supply on the 2-pin input.
• A SIP server such as a Grandstream UCM (Unified Communications Manager) for calls.
• Only if you want meeting room booking, a UCM with Wave.
• If it drives a lock from its own relays, the lock and a power supply for the lock.

Installation

An intercom installer should fit it, although the wiring is light. It mounts flat on the wall with the 0° bracket or stands on a desk or angled wall position with the 20° bracket; both brackets come with it. The job involves a network cable to a PoE port or a 12 V DC feed, wiring any door sensors, buttons or locks to the alarm inputs and relays, and registering it to the SIP server. The unit measures 182 x 122 x 26.2 mm and weighs 408 g.
