0-35° Adjustable Mount for the Alarm.com ADC-VDB770 Video Doorbell
Built for the Alarm.com ADC-VDB770 — Alarm.com's next-generation Wi-Fi video doorbell with a portrait 1440×1920 head-to-toe view, expansive 150° vertical × 115° horizontal field of view, package detection, touchless doorbell ringing, two-way audio, IR night vision, and HDR for high-contrast porch lighting. Standard kit on Brinks Home, Monitronics/Brinks Home Pro Series, and many ADT-affiliate dealers. The bracket cradles the slim VDB770 body specifically and the 0-35° dual-axis ball joint aims the wide frame in any direction. Outdoor PETG, made-to-order in the USA.
Custom-Fit for the Alarm.com ADC-VDB770
This bracket is shaped specifically for the Alarm.com ADC-VDB770 Wi-Fi Video Doorbell Camera — Amazon ASIN B08R6JB5KR. Alarm.com's flagship 2MP wired doorbell with: 1440×1920 portrait/head-to-toe video resolution, 150° vertical × 115° horizontal field of view, HDR, IR night vision (15 ft), package detection analytics, touchless ringing (motion-triggered automatic notification), two-way audio, and full integration with the Alarm.com platform via Brinks Home, Monitronics, ADT-affiliate dealers, and other Alarm.com-powered alarm services. Wired-only operation: requires existing 16-24V AC doorbell wiring + Alarm.com service plan.
Does NOT fit: the Alarm.com ADC-VDB750 (older 165° H × 145° V body — different shape), VDB-755P PoE Pro (different chunkier station body), VDB-780B Battery (rounder battery body), or any non-Alarm.com doorbell. Each Alarm.com doorbell has its own dedicated mount listing.
Confused which Alarm.com doorbell you have? The VDB-770 is the slim wired model with portrait/vertical lens orientation, was launched 2021 and has the head-to-toe 1:1-style aspect ratio (taller frame than wide). VDB-750 has a smaller squarer lens face. VDB-780B has a battery compartment + charging port. VDB-755P is much chunkier with a PoE Ethernet port.
Pro-Monitored + Touchless + Head-to-Toe — Aim It Right
The VDB-770 is the most-installed Alarm.com doorbell at the moment — Brinks, Monitronics, COPS, and many ADT-affiliate dealers all standardize on it. Touchless ringing means the doorbell auto-notifies you on motion, no button press needed. Package detection analytics call out specific delivery events (separate from generic motion alerts). And the head-to-toe portrait frame catches the visitor's face AND the package on the doormat in one shot.
That head-to-toe advantage only works when the camera is aimed correctly. This 0-35° dual-axis swivel mount rotates the VDB-770 in any direction up to 35°, locks permanently with set screws, and routes the existing 16-24V wires cleanly through the joint. Locked aim is essential for pro-monitored installs — drift can register as a tamper event with your Alarm.com central station.
Two-Axis Aiming, 0-35° Range
One smooth ball joint. Aim left, right, up, or down — all the way to 35° in any direction. Lock the angle with set screws. Done.
Internal Wire Routing — Hidden & Protected
Low-voltage wires enter from the wall, pass through the hidden internal channel inside the ball-joint mount, route through the front adapter, and connect directly to the doorbell terminals. No exposed wiring, no weather risk.

- Custom Bracket for VDB-770: Pre-shaped pocket fits the slim VDB-770 body — flush, no rattle, no obstruction of the head-to-toe lens, mic, or speaker.
- Dual-Axis 0-35° Swivel: Aim the 1440×1920 head-to-toe portrait frame precisely; lock with set screws.
- Wire Pass-Through: Routes 16-24V AC doorbell wires through the joint cleanly.
- Outdoor-Rated PETG: UV-stable, freeze-tolerant.
- Siding Compatible: Flat surfaces and lapped siding up to 1.8" wide.

- Pro-Monitoring Friendly: Locked set screws prevent aim drift / tamper false-alerts at your Alarm.com central station.
Installing on the Alarm.com ADC-VDB770
- Coordinate With Your Alarm Dealer: If your Alarm.com system is professionally monitored (Brinks, Monitronics, ADT-affiliate, etc.), call your dealer before swapping the mount and request a 1-hour test mode. Replacing the doorbell can register as tamper.
-
Power Down: Turn the breaker off at the chime circuit. Verify with a tester at the existing wires before pulling them through the mount.
- Verify Wiring: Confirm 16-24V AC at the doorbell location with at least a 10VA transformer. The VDB-770 is wired-only, no battery option.
- Mount the Base: Pull the doorbell wires through the hole in the swivel base, position vertical (the VDB-770's head-to-toe portrait orientation works best vertically), secure with #6 screws (PH2 driver). Anchors as needed.
- Attach the Swivel: Route the wires through the swivel center, attach to the base with four #4 / PH1 center screws.
- Connect & Mount the VDB-770: Connect the two doorbell-circuit wires to the VDB-770's screw terminals. Snap onto the bracket using the screws PROVIDED WITH THIS MOUNT (PH1 driver) — not Alarm.com's stock plate.
- Pair via Alarm.com / Customer Site: Restore power. Your dealer can re-pair the doorbell to your Alarm.com account remotely, or you can use the Alarm.com mobile app to add it (Add Device → Video → Scan QR code on the back).
- Aim & Lock: Live View in the Alarm.com app → adjust the swivel until the head-to-toe frame catches both the package zone (bottom) AND the visitor face (top) → tighten the set screws.
- Configure Detection Zones + Touchless Ringing: In the Alarm.com app: set motion zones to exclude the street, enable package detection, and configure touchless ringing thresholds. Confirm professional monitoring is back online if you put it in test mode.
Service tip: the VDB-770 only works through Alarm.com — meaning you need an active service plan from a dealer. If you cancel service, the doorbell becomes inert (no live view, no recordings). Plan ahead if you're switching alarm providers — or shop our Ring Battery Pro / Nest Wired listings as Alarm.com-free alternatives that work standalone.
