What the existing connection tells
In many houses, the transformer is hidden in the meter box or behind the doorbell. Therefore, it is only after installation that it becomes clear that the doorbell does start up but reacts unstable when ringing.
advice
Connect doorbell to existing transformer
an existing transformer can sometimes stay, but a doorbell with video and app often asks for more than a traditional push button.
The technical choice
Find the specifications for the transformer, doorbell, and new doorbell. Investigate how the old wiring runs and whether the chosen doorbell needs the existing doorbell or a separate module.
What you let me arrange
Use only a suitable configuration for the exact model. Replace or add a module when the existing power supply does not meet the required values.
Delivery to the door
Test video call, ring, speak back and make multiple notifications. Check if the old doorbell, if retained, responds correctly and does not constantly reconnect the doorbell.
