I use the Eufy E340 with my original doorbell chime. It was very easy to install and the small extension wires were so convenient. it was amazing that they thought to include them, It was very easy to connect to the home base and get working quickly.
Easy to install, however, the wedge needed to be reversed and a spacer added to have the camera point at about a 15 degree angle towards the entrance center. I guess eufy didn't take into account that most exterior door frame trims are not flat.
