Set your eufy Video Doorbell S4 on a wall corner and turn it 45° toward the people walking up. This 45° Corner Mount has a 3/4-inch base that slips onto tight inside or outside corners and skinny trim where a standard mount rocks or overhangs — so the S4's 180° × 180° view lands on the approach instead of the neighbor's driveway.

The angled face carries our Eufy adapter bracket, confirmed to fit the S4. Choose Eufy Video Doorbell S4 (2026) in the Doorbell Model dropdown.

Printed to order in the USA from UV-stable PETG. Free shipping over $100, backed by our Replacement Guarantee. Doorbell specs: eufy Video Doorbell S4.

Tall doorbell, narrow base. The S4 is about 6.6 inches tall and 2 inches wide; this base is 3/4 inch × 2.5 inches. The doorbell overhangs the base by design — that is what lets it sit on a corner. Send a photo of your corner and we will confirm clearance before we print.

Installing Your 45° Corner Mount on an eufy Video Doorbell S4

  1. Select your doorbell: Choose Eufy Video Doorbell S4 (2026) in the dropdown so we print the matching bracket.
  2. Remove the old doorbell: Switch off the breaker and disconnect the two wires.
  3. Position the base: Thread the wires through, set the 45° corner base on the inside or outside corner and sight the aim toward the walkway with a level.
  4. Anchor it: Fasten the base to the corner trim with the provided #6 wall screws and a #2 Phillips screwdriver (pilot holes optional).
  5. Attach the bracket: Attach the Eufy bracket to the mount face with the small center screws (usually preinstalled). Use a #1 Phillips PRECISION screwdriver.
  6. Wire and mount the doorbell: Connect the two wires to the S4 terminals and mount the doorbell onto the bracket with the screws PROVIDED WITH THIS MOUNT (not eufy's stock plate).
  7. Finish up: Restore power, open the eufy app and check the field of view and activity zones.

Tools: #2 Phillips screwdriver, #1 Phillips PRECISION screwdriver, drill (optional pilot holes), level, and a multimeter to confirm 16-24V AC at the wires.

FAQ — Corner Mount Angled 45° for the eufy Video Doorbell S4

Will this also fit my E340 or S330?
The S4 rides on the same Eufy adapter bracket family as the E340, S330, C31, C30 and S220, but each model has its own listing in our Eufy collection. Order from the listing for the doorbell you own so the bracket and photos match your install.
What are the base dimensions?
The base is 3/4 inch wide and 2.5 inches long with 2-inch center-to-center hole spacing (customizable). It holds a fixed 45° corner angle with roughly 1 inch of offset from the corner.
Can I change the hole spacing or base length?
Yes — both are made to order. Hole spacing runs from 1-3/8 inch to 4-1/8 inch, including slotted holes, and the base length can be changed with the add-on.
What if I need a different corner angle?
We also make 15° and 30° offset corner mounts plus an adjustable 0-90° corner mount for fine-tuning the aim.
The S4 is wired-only. Does this mount handle the wiring?
Yes. Every one of our mounts has a wire channel through the body, so the two low-voltage doorbell wires run from the wall, through the mount, to the S4's terminals. The S4 needs 16-24V AC at 10-40 VA; its small internal battery is only a backup for power outages, so hardwiring is required.
Does the 180° × 180° camera see the wall it is mounted near?
On a corner it can. That is the point of the 45° turn — it swings the lens away from the adjacent wall so more of the panoramic image is porch and walkway instead of siding.
How do you make sure I get the right bracket?
Upload photos of your doorbell and corner with the photo upload option on this listing. We review them before your order ships.
Will sun and cold affect it?
No. It is printed in UV-stable PETG made for year-round outdoor use, through freezing winters and summer sun.
