Video-door chime

For the wired 2K video door bell do loose my home door bell chime?

Do you mean would this be a replacement for your current doorbell that has a chime inside?

Yes, when you install the wired doorbell using existing wires of your “old” doorbell, the “old” chime will not work anymore. That is the reason you get a wireless chime with the wired doorbell that you can place anywhere in the house.
