Wired 2k doorbell + 2k cam?

I plan on installing wired doorbell 2k in my front door. Is there benefit having a eufy cam there? What does the cam do that the wires doorbell doesn’t do ? Please help!

Anyone ? Anyone !

I have the cam and doorbell on the same area. Gives video from different angels. The cam was there before the bell. And did not have more options for the set of two. Maybe overkill. Still handy.
