Grandstream GDS3726 One-Button Video Door Station with RFID/NFC

The Grandstream GDS3726 packs a 4MP sensor, a dual-frequency card reader, NFC and Bluetooth behind a simple one-button front. It suits villas, building lobbies and offices where a visitor only needs to press one key, while residents and staff get in by card, phone or QR code.

====

The Grandstream GDS3726 is built for entrances that want a clean look outside and full control inside. Visitors see a single button; pressing it rings an indoor station, an IP phone or a smartphone. Residents and staff get in by card, phone or QR code, with no keypad on the wall.

Why one button instead of a keypad?

Keypads make sense in offices, but on a villa wall or a building lobby they mean more buttons exposed to sun and tampering, and PIN codes that end up shared with every worker. The GDS3726 replaces the PIN with credentials tied to the person:

• RFID cards at 13.56MHz or 125kHz, up to 5,000 cards.
• NFC from a phone.
• The SecureAccess app over Bluetooth BLE 5.0.
• QR codes you send to a guest or a technician.
• Door opening from a SIP call or through the HTTP API.

Grandstream GDS3726 camera

The camera uses a 1/3-inch 4MP HDR sensor with AI ISP. The F2.2 lens covers 127° horizontally and 70° vertically, so a visitor standing close still appears head to shoulders. Six white LEDs and an AI fill light work at night, and a PIR sensor detects motion at 3 to 5 m alongside AI motion detection.

Locks, alarms and integration

The GDS3726 has two solid-state relays rated 30VDC/2A. Three alarm inputs take a door contact and an exit button, and two alarm outputs, Wiegand 26/34 and RS-485 link it to other access systems.

Where it fits in Saudi Arabia

• Villa and rest-house walls: a camera doorbell that reaches your phone when you are away.
• Apartment lobbies: residents use cards; visitors press the button to call the guard or an indoor station.
• Small offices and clinics: staff tap in with NFC or the app.
• Back doors of shops and restaurants: suppliers use a temporary QR code.

Installation details

The metal body is rated IP66 and IK10 for metal and lens and runs from -30 to 60°C. Power it with 802.3af PoE or 9–36V DC at 12W, which lets you reuse a power source already at the gate. It measures 204 × 87 × 35.5 mm, weighs 1.55 kg and has a microSD slot for up to 256 GB.

Compatibility

It registers as a SIP device on PBXs such as the Grandstream UCM6300, calls GSC357x stations, GXV video phones and WP phones, and can be added to NVRs that support ONVIF Profile S.

GDS3726 or GDS3725?

The GDS3726 matches the GDS3725 in everything except the front: no keypad, so no PIN entry, no Hostage Code and no Building Mode.

Frequently Asked Questions

Can the Grandstream GDS3726 open with a PIN code?

Not from a keypad, since it has one doorbell key. Use a card, NFC, the app, a QR code or a SIP call. For PIN entry, choose the GDS3725.

Can the doorbell ring my phone?

Yes. Use GS Wave for answering and viewing, and the SecureAccess app for Bluetooth door opening.
