In general all mechanical doorbells can be compatible if they have 

  1. A Trafo with min 9.6W  ( 8-12V / 1,5A for example) 
  2. Enough space to add the power kit adapter from your electrician

 

I have installed everything but my old doorbell is humming!

 

Please check your Power Kit Adapter installation. In 90% of this happening the Power Kit Adapter is not installed. In minor occasions the doorbell is too old or to low powered to drive a video doorbell . If this happens a new mechanical doorbell ( 8-10 Euro) with a 12V Trafo can help out.
