Mounting the Doorbell
Finding a Mounting Spot: Use the live view in the app to check the field of view. Recommended mounting height is 48 inches (1.2m) from the ground. Avoid placing the doorbell too close to a side wall to prevent IR reflection, which can cause blurry night vision.

Installation:
- Wooden Surface: Use the provided screws to secure the mounting bracket directly.
- Hard Materials (Brick/Concrete/Stucco): Drill 2 holes using a 15/64 inch (6mm) drill bit, insert anchors, and secure the bracket with the provided long screws.
- Angle Adjustment: Use the 15° mounting wedge if you need to adjust the viewing angle.
Once the bracket is mounted, align the doorbell with the top of the mount and snap the bottom into place.
Detaching the Doorbell
To remove the doorbell for charging or maintenance, insert the provided doorbell detaching pin into the hole on the bottom of the device, press, and lift the bottom of the doorbell to release it.

Charging the Doorbell
Charge the doorbell using a universal USB charger that delivers 5V 1A output. A full charge from 0% to 100% takes approximately 6 hours. The LED will be solid orange while charging and solid blue when fully charged.
