Start by ensuring your current system has the right power output to support the new device. Check the voltage specifications of your new unit to confirm it matches the existing transformer. This step is vital to prevent damage during installation and ensure smooth operation.
Next, carefully remove the old device, taking note of the connections to avoid any confusion later. Typically, you’ll find a pair of wires attached to the old system–one for power and one for the chime. These will need to be reconnected to the new unit based on the updated pinout configuration.

If you’re replacing a mechanical chime, be prepared for a possible modification to your setup. The newer systems often require digital chimes that work with the advanced technology, so make sure to follow the manual for adjustments and connections.
Wiring Setup for Video Doorbell

Ensure your power supply is adequate before beginning installation. The device requires a 16-24 VAC transformer. If your existing transformer provides less than this, you may need to replace it with a compatible one. Once confirmed, turn off the power at the circuit breaker to avoid any electrical hazards.
After confirming the voltage, carefully remove the old system and connect the wires to the new unit. You’ll typically find two wires: one for power and one for the chime. Attach these to the corresponding terminals on the new device, ensuring proper orientation. If your system includes a digital chime, make the necessary adjustments as per the instructions to sync the two components.

Step-by-Step Guide to Connecting Your Video Doorbell to Existing Wires

Start by turning off the power at the circuit breaker to avoid any accidents. Ensure that your existing setup uses a transformer providing 16-24 VAC. If your transformer is underpowered, replace it with one that meets these specifications. This is crucial for proper operation of the new unit.
Once the power is off, carefully remove the old system, noting the wiring connections. You should find two wires connected to the previous device: one for the power input and one for the chime output. If the old setup has additional wires, consult the installation guide for specific instructions on where to connect them.
Connect the power wire to the terminal marked “Power” and the chime wire to the “Chime” terminal. Ensure that the connections are secure and that there is no exposed wire that could cause a short. If your unit includes a mechanical or digital chime, you might need to adjust the settings accordingly, depending on the manufacturer’s recommendations.
Once the wires are securely attached, mount the device in its location and turn the power back on. Test the functionality by pressing the button on your device and ensuring the chime rings correctly. Follow the instructions provided in the setup guide to complete the installation and finalize any configuration through the mobile app.
