Hey @Lbeato! If you are installing the Video Doorbell 2 and are using the existing wiring, I recommend following our recommend steps for installation which can be found here. Keep in mind, an existing chime kit should be compatible for it to work as intended. Check out our Chime Compatibility List to ensure the Doorbell 2 will work with that chime kit.
If this concern persist, please reach out to our support team, at 800-656-1918, for more in-depth troubleshooting.
