Grandstream GDS3727 Compact Video Door Station with Wi-Fi 6

The Grandstream GDS3727 is the lightest, slimmest model in the GDS372x series and the only one with dual-band Wi-Fi 6. It keeps the 4MP sensor, dual-frequency card reader, NFC and Bluetooth, and suits office, apartment and clinic doors inside buildings where pulling a network cable is hard.

====

The Grandstream GDS3727 solves a familiar problem in existing buildings: an office or apartment door needs a video intercom, but no network cable reaches it. It is the only GDS372x model with Wi-Fi 6, and weighs just 524 g.

Grandstream GDS3727 with Wi-Fi 6

The unit supports dual-band Wi-Fi 6 (802.11ax on 2.4GHz and 5GHz). Setup takes three steps:

• Connect it once with an Ethernet cable and open the web interface.
• Choose your network under Wi-Fi Settings and join it.
• From then on it runs on a 12V supply alone and reconnects by itself after a reboot.

The 10/100 Mbps port with 802.3af PoE stays available if you prefer a cable. Note that Wi-Fi replaces only the data cable: power still comes from a 12V adapter of at least 1A, which is not in the box. It fits doors with a power point nearby but no network jack.

Same camera and credentials, smaller body

The GDS3727 carries the same 4MP HDR sensor as the GDS3725 and GDS3726, with video up to 1920×1080, an F2.2 lens covering 152° diagonally, six white LEDs and a PIR sensor with a 3 to 5 m range. Door opening options:

• RFID cards at 13.56MHz or 125kHz, up to 5,000 cards.
• NFC, and the SecureAccess app over Bluetooth BLE 5.0.
• Visitor QR codes, SIP calls and the HTTP API.

Lock and alarm wiring

There is one solid-state relay rated 30VDC/2A. Use COM and NO for a fail-secure electric strike, or COM and NC for a fail-safe magnetic lock. Two alarm inputs take a door contact or an exit button, and you also get RS-485 and a microSD slot for up to 256 GB.

Installation

It measures 180.6 × 86.6 × 29 mm and mounts on an 86 box, a 1-gang box or directly on the wall. Grandstream recommends placing the lens at about 130 cm with 50 cm of clear space in front, out of direct sunlight. Ratings are IP66 and IK07, the operating range is -30 to 60°C, and power is PoE or 12V DC.

Where it fits in Saudi Arabia

• Department doors inside a company building: staff badge in, visitors call the department directly.
• Apartments in a building that already has a main entrance intercom.
• Clinics inside a medical complex: a camera at reception and card access for staff.
• Rented offices where new cabling through the walls is not allowed.

Compatibility

It registers on SIP PBXs such as the Grandstream UCM6300, calls GSC357x stations, and Grandstream publishes an official guide for pairing GDS37xx units with WP8xx Wi-Fi phones. Management is through GDS Manager 2.

GDS3727 or GDS3726?

Pick the GDS3727 when you need Wi-Fi and a light body. Pick the GDS3726 when you need more than one lock or higher impact protection: it has two relays instead of one, three alarm inputs instead of two, Wiegand 26/34, IK10 instead of IK07 and 9–36V DC input, at 1.55 kg.

Frequently Asked Questions

Can the Grandstream GDS3727 run on Wi-Fi without a cable?

Yes, after first setup. Connect a cable once to configure Wi-Fi, then it runs on a 12V adapter and Wi-Fi. It still needs a power source.

Can it be installed outdoors?

It is rated IP66 for water and dust and IK07 for impact. If you need IK10 impact protection, choose the GDS3726 or GDS3725.

How many locks can it control?

One, through a single 30VDC/2A relay. For two locks or a lock plus a gate, choose the GDS3726.
