Step-by-Step Instructions

1

Download app and create account

5 minutes

Before starting installation, download the manufacturer's app (Ring, Nest, etc.) and create an account. This is needed to complete setup and will walk you through installation.

2

Turn off power to existing doorbell

5 minutes

Turn off the breaker that powers your doorbell. This is typically the same circuit as the transformer, often in a closet, basement, or garage. Or, turn off the breaker and test at the doorbell.

Pro Tip

If you're not sure which breaker, turn off the main breaker to be safe.

3

Remove old doorbell button

5 minutes

Unscrew the old doorbell button from the wall. Gently pull it away to expose the two low-voltage wires behind it. Note the wire positions.

Pro Tip

Doorbell wires are low voltage (16-24V AC), but it's still best to turn off power.

4

Check transformer voltage

5 minutes

Most video doorbells require 16-24V AC. Check your transformer (usually in basement, closet, or garage) for its output rating. If it's below 16V, you may need to upgrade it.

Warning

An underpowered transformer can cause the doorbell to malfunction or not charge properly.

5

Mount the bracket

10 minutes

Position the mounting bracket over the existing holes if they align, or mark new holes. Ensure the bracket is level. Drill pilot holes if needed and screw the bracket to the wall.

Pro Tip

Use a wedge mount if you need to angle the camera for a better view of your porch.

6

Connect the wires

5 minutes

Connect the two doorbell wires to the terminals on the back of the video doorbell. For most models, it doesn't matter which wire goes to which terminal - doorbell wiring is not polarized.

7

Attach doorbell to bracket

3 minutes

Snap or screw the video doorbell onto the mounting bracket. Most have a security screw on the bottom to prevent theft.

8

Restore power and complete setup

10-15 minutes

Turn the breaker back on. The doorbell should power up and show an LED indicator. Follow the app instructions to connect the doorbell to your WiFi network and configure settings.

Pro Tip

For best results, ensure strong WiFi signal at your front door. A WiFi extender may be needed.

Common Mistakes to Avoid

  • Insufficient transformer voltage (doorbell doesn't charge or work properly)
  • Poor WiFi signal at door location
  • Wrong mounting angle (doesn't capture visitors properly)
  • Not setting up app before installation

Safety Warnings

  • Doorbell wiring is low voltage but still turn off power before working
  • Don't install where it can be easily stolen without security screw
  • Ensure doorbell is rated for outdoor use in your climate

When to Call a Professional

If you don't have existing doorbell wiring, if you need to upgrade the transformer, or for battery-only models that need a custom power solution.
