DoorBird Video Intercoms for Gates in Maryland

DoorBird makes IP video intercoms, developed and made in Germany. When a visitor presses the call button, your phone rings with live video: you can see them, talk to them and open the gate from anywhere in the DoorBird app. ADP Garage Door Repair is an authorized DoorBird dealer. We install DoorBird intercoms together with gate operators, wired to the operator so the app, a PIN code or an RFID tag opens your driveway, community or business gate.

• 20+ gate jobs completed since June 2020, all gate brands
• 8 phones or tablets a DoorBird can ring at once with video and voice
• 50+ materials, finishes and colors for DoorBird door stations

Job count from our own Housecall Pro records; it covers every gate job we have done, 10+ of them in the last two years, not only jobs with a DoorBird. Product facts on this page are from DoorBird’s website (doorbird.com), manuals and data sheets, checked November 2026.

Why a DoorBird at the gate

• Answer the gate from your phone. Push notifications with video and two way audio, at home or away, so you can let in a guest or a delivery without walking down the driveway.
• Open it the way you choose. The app, PIN codes, RFID tags and, on some models, a fingerprint, each with schedules you set in the app.
• Works with your gate operator. DoorBird door stations switch an electric door, gate or garage opener through a two wire, potential free relay contact, so they pair with the LiftMaster and Maximum Controls gate operators we install.

DoorBird’s current door stations are the D11x series for single family homes, the D22x series (successor to the D21x) with a 5 MP camera and built in RFID and Bluetooth, and the D31x series with a 7 inch touch display. Indoor video stations, the A1121 keypad and RFID access device and the A1081 I/O door controller complete a gate system.

Materials and finishes

DoorBird door stations come in more than 50 materials and colors: brushed V2A stainless steel, V4A stainless steel (resistant to salt water and grinding dust) for coastal or industrial sites, PVD bronze, gold and brass finishes, chrome, and powder coatings in many RAL colors. DoorBird’s 3D configurator lets you choose size, buttons and finish.

A DoorBird door station has a relay, a switch with no power of its own, that is wired to the gate operator’s open input with two wires. When you tap open in the app, or someone enters a valid PIN or RFID tag, the relay closes and the gate operator opens the gate. DoorBird recommends putting that relay indoors in its A1081 I/O door controller so nobody can open the gate by tampering with the outdoor station.

• The relay. On the D11x it is a bistable latching relay rated up to 24 V DC or AC and 1 A. It supplies no power: the device it switches has its own power supply. It keeps its state through a power loss, and its default position and how long it closes are set in the DoorBird app.
• The safer way. DoorBird warns that a door opener wired straight to the outdoor station could be triggered by someone who breaks the station and shorts the wires. The A1081 I/O door controller sits in a protected indoor spot, talks to the door station over the encrypted network, and controls up to three doors or gates. The app shows whether each relay is open or closed.
• An inside button. D11x and D21x stations have an input for a door opener button inside the house, which triggers the first relay.

• Notifications with video. When the call button is pressed, up to 8 smartphones or tablets get a push notification with video and voice, or IP phones get a voice or video call.
• See and talk first. Watch live video and speak with the visitor before you open the gate, from home or anywhere in the world.
• Open doors, gates and garages from the app, through the door station’s relay or an A1081 controller.
• Visitor history. The app shows who rang and when. DoorBird says cloud recording of single images is free, with no monthly fees.
• Access settings. PIN codes, RFID tags and fingerprints, with time frames and schedules, are set up in the app.
• Motion alerts. The built in motion sensor can send an alert to your phone or switch a relay, for example to turn on an outdoor light.

DoorBird says its intercoms work with more than one hundred smart home, access control and building management systems through open interfaces and APIs, including Control4, Crestron, Loxone, KNX, Home Assistant, Synology and SIP phones.

• Home automation: Control4, Crestron and Crestron Home, Loxone, KNX, Home Assistant, openHAB, Homey, RTI, Universal Remote Control, Fibaro and others.
• Smart locks: Yale, August, Kwikset, Nuki, Kevo and others.
• Garage doors: LiftMaster and Chamberlain, and Aladdin Connect, are on DoorBird’s integration list.
• Video recorders and phones: Synology, QNAP, Milestone, Hikvision and other NVRs, plus SIP phone systems such as Grandstream, Yealink and Snom.

From DoorBird’s integrations page and D22x series page (doorbird.com), checked November 2026. Each integration is set up in the partner’s system; ask us which fits what you already have.

• Power over Ethernet. DoorBird stations run on PoE (IEEE 802.3af Mode A) over a network cable, which DoorBird recommends, or on the supplied plug in power supply. They do not use a battery.
• Cable length. A network cable can run up to 80 m (262 ft) from the switch or router; longer runs need a network switch in between. Where only two wires exist, DoorBird’s A1072 2 wire Ethernet PoE+ converter carries network and power over them.
• Wi-Fi. Only some models (D1101V, D1102V) connect by 2.4 GHz Wi-Fi; DoorBird recommends a cable for stability.
• Placement. DoorBird says to avoid direct sunlight on the station: it can overheat the housing and damage the camera sensor, and defects from direct sunlight are not covered by warranty. In a gate pillar or mailbox, the space must drain and stay dry.
• Power supplies. Use only DoorBird’s own power supply units; DoorBird says the warranty ends if another one is used.
• Warranty. DoorBird offers a 2 year warranty on its products under its terms of business.
