How to Install a Wired Video Doorbell: A Step-by-Step Guide
This guide provides a safe, systematic approach to replacing a traditional doorbell with a wired smart video doorbell. Following these steps ensures a secure electrical connection and a fully functional chime system.
What You'll Need
- Video doorbell kit (including mounting bracket and screws)
- Phillips and Flat-head screwdrivers
- Voltage tester or multimeter
- Power drill (if new holes are required)
- Electrical tape
Steps
Step 1: Power Down the System
Locate your home's electrical panel and switch off the breaker providing power to the doorbell chime. This is a critical safety step to prevent electrical shocks or short-circuiting your device during installation.
Step 2: Verify Transformer Voltage
Use a multimeter or voltage tester to check the transformer output. Most video doorbells require 16-24V AC; if your transformer is underpowered, the doorbell may reboot frequently or fail to ring the internal chime.
Step 3: Remove the Existing Doorbell
Unscrew the old doorbell button from the wall and gently pull it away to expose the two wires. Disconnect the wires and ensure they do not slip back into the wall cavity.
Step 4: Install the Mounting Bracket
Position the provided mounting bracket against the wall, ensuring it is level. Secure it using the provided screws, drilling pilot holes if you are installing into masonry or hard wood.
Step 5: Connect the Doorbell Wiring
Wrap the two existing house wires around the screw terminals on the back of the video doorbell. Since AC power is non-polarized, the order of the wires typically does not matter, but ensure the connections are tight and no bare wires are touching.
Step 6: Secure the Device
Push the doorbell unit firmly into the mounting bracket until it clicks into place. Use the security screw provided in the kit to lock the device to the bracket, preventing theft or tampering.
Step 7: Configure the Chime Box
If your kit included a chime connector or capacitor, install it inside your internal chime box. This regulates the power flow and prevents the chime from humming or failing to trigger.
Step 8: Restore Power and Test
Turn the breaker back on and wait for the device to boot up. Press the doorbell button to verify that both the internal chime rings and the mobile app receives a notification.
Expert Tips
- If wires are too short, use a wire nut and a small piece of copper extension wire to reach the terminals.
- Apply a small bead of silicone sealant around the top and sides of the doorbell to prevent rainwater from entering the wall.
- If the chime doesn't ring, check the 'Chime Type' settings in the device app to ensure it is set to 'Mechanical' or 'Digital' based on your hardware.
