If the wiring is too complicated, we would recommend you disconnect all wires on original chimes and connect all wires back to the output terminals on the transformer. If you want to power up two video doorbells, please use a 24V 40VA transformer. See pictures.


If you want to install more than two video doorbells, refer to the wiring diagram to install additional doorbell transformers and wiring.


 

Special Case - Reuse the Existing Intercom Wiring

The eufy wired video doorbell doesn’t work with existing intercom power and signal systems, but you can reuse the existing wiring if you no longer use the Intercom wiring.

1. Trace the wires from the outdoor device back to the indoor. For example, you select the specific color of the wires on the outdoor device and find the wires with the same color indoor.

2. Replace the original intercom device at the front door with a eufy wired video doorbell. Connect to the selected wires.

3. Get a power adapter to charge the wired doorbell (19V - 0.6A power adapter).

4. Connect the wires on the power cord to the selected intercom wires indoors.

5. Plug in the power adapter and check if the video doorbell is powered up.

 


To avoid the hassle of handling the wires, please connect the doorbell with a power adapter. For more information, please read How to Hardwire Your eufy Wired Doorbell without Existing Wires.
