Upgrading from VDB770 to VDB775

Is the VDB770 to VDB775 doorbell upgrade a straightforward swap out?

In other words do I need to do every step of the install, or would it leverage the same powersupply/wiring and I just need to swap the device itself. Mine was installed by a pro, so I have no idea how to do anything more than unscrew it, swap over wires and connect the new one. I am capable of provisioning.

The VDB775 is meant as a replacement. The power requirement for AC transformer is 16-24 VAC, 10-40VA (16VAC, 10VA recommended). Your transformer should state what its rated for. Similarly, the 770 is AC transformer 16-30V AC, 10-30VA

More information on the 775 including installation instructions can be found below. While we do not currently carry this camera, we should have it available on the store front soon. Otherwise, compatible equipment can be purchased elsewhere and still be used with service.

Can you tell if I need a new transformer from this? It looks like 770 and 775 transformer specs are similar.

The item in the picture is the chime. The transformer for a doorbell usually looks like the picture below. It is usually located near the chime, garage, entry closet, or attic. The transformer is where we will be able to tell if it provides enough power for the doorbell
