Authentic part manufactured by eufy. Used for adjusting the installation angle and direction. Compatible with eufy Video Doorbell S220.
The 15° angle was exactly what my doorbell needed to see the walkway instead of just the wall. Installation took five minutes with the existing screws.
My porch is set back from the sidewalk so the camera kept missing people walking up. This wedge fixed that in about ten minutes, and the angle is just enough to catch faces instead of the tops of heads. Fit the existing mount holes perfectly with no drilling.
The wedge clicks into place cleanly and angles the doorbell just enough to catch visitors at the top of our porch steps, which the flat mount completely missed. Feels solidly made and the 15 degrees is subtle but exactly right for our setup.
