Grandstream GDS3727 Compact IP Video Door Phone, Wi-Fi 6, RFID/NFC, IP66

Overview

The Grandstream GDS3727 is the compact, plastic-cased video door phone (IP video door station) in the GDS3720 series. It keeps the 4 MP camera, card reader and SIP (Session Initiation Protocol) intercom of the larger models and adds dual-band Wi-Fi 6, so it can go on a door that no network cable reaches. It suits front desks, reception areas and villa entrances where a quick, cable-light installation matters more than vandal resistance.

Is it right for you?

• Choose it for a sheltered or lower-risk door where Wi-Fi saves running a cable. For exposed or high-risk entrances the metal, IK10-rated GDS3726 is the sturdier choice.
• It has one relay and no Wiegand port, so it suits a single-lock door rather than a door feeding a separate access controller.
• One call button and no keypad: for PIN entry at the door choose the GDS3725.
• Up to 5,000 users and 5,000 cards.
• Calls need a SIP server or an indoor station.

Key features

• Dual-band Wi-Fi 6 (802.11 a/b/g/n/ac/ax, 2.4 GHz and 5 GHz), plus a 10/100 Mbps PoE port and Bluetooth Low Energy (BLE) 5.0.
• 1/3 in 4 MP camera with HDR, 1080p at 30 fps, 127° horizontal view and up to 120 dB wide dynamic range (WDR); 6 white fill-light LEDs with auto brightness for night.
• Reads 13.56 MHz IC cards (MIFARE Classic 1K/4K, Ultralight, Plus and DESFire) and 125 kHz ID cards, plus NFC, QR codes and app unlock.
• One solid state relay (SSR) output (NO/COM/NC) rated 30 V DC/2 A, 2 alarm inputs and RS-485.
• IP66 weather rating and IK07 impact rating; works from -30 to 60 °C.
• PIR sensor with 3 to 5 m range, 2 microphones and a 3 W speaker, and a microSD slot up to 256 GB.
• ONVIF Profile S, so the camera can record to a video recorder.
• Small and light at 180.6 x 86.6 x 29 mm and 0.524 kg.

What else you need

• Power: a PoE switch port (802.3af Class 3) or a 12 V DC supply of at least 1 A, 12 W. When it connects over Wi-Fi it still needs the 12 V DC supply.
• Calls: a SIP server such as a Grandstream UCM (Unified Communications Manager), or direct IP peering with an indoor station such as the Grandstream GSC3570.
• An electric lock and a power supply for the lock.
• Cards and fobs: G-AC1 (MIFARE Classic EV1) or G-AD2 (MIFARE DESFire EV3) cards or fobs for your users.

Installation

An intercom or access control installer should fit it. It wall mounts only: the GDS372X flush-mounting box does not apply to this model. The job involves fixing the unit to the wall, running either a network cable to a PoE port or a 12 V DC feed with Wi-Fi for data, wiring the lock to the relay, and configuring the unit through its web interface.

Software and licences

• Managed from its local web interface, with GDS Manager software, or through GDMS (Grandstream Device Management System) UC and GDMS SecureAccess.
• The SecureAccess app handles Bluetooth and QR code entry and remote unlock on a phone.
• SIP, ONVIF Profile S, HTTP API and TR-069, with Home Assistant integration supported. No licence is listed.

Before you buy

• On Wi-Fi it still needs a 12 V DC supply of at least 1 A.
• One relay and no Wiegand port, so it suits single-lock doors.
• Wall mount only; the flush-mounting box does not fit this model.
• Plastic case rated IK07: for exposed or high-risk entrances choose the IK10-rated GDS3726.
• Calls need a SIP server or direct IP peering with an indoor station.
