Video doorbell on which wall?

The feedback from the door manufacturer just came in. He cannot offer a front door with integrated ekey.

Now we still need a place for the ekey xLine (new ekey fingerprint in the standard switch program format).

Now only the following division actually works.

Red = ekey xLine
Blue = video doorbell
Green = mailbox

possibly Green and Blue can still be swapped

Mounting height ekey = 1.20m-1.30m recommended
Video doorbell = 1.20m recommended.

I would set both at about 1.20m

Hello, we are wondering which side of the door is the best place to mount a video doorbell. I have attached our floor plan of the entrance area. There is the option to mount it on the right side of the front door on the protrusion or on the left side of the door on the wall. What would you say is the better option? A simple Ring, Nest, or eufy doorbell is planned.

What about the fence? Do you not have or make a fence? We install one on the fence. The new eufy.

No fence is planned in front of the house.
We only have a small flower bed in front of the house.

We have to place it on one of the 3 walls.

The new arrangement is the only sensible one, right?

Red = ekey xLine
Blue = video doorbell
Green = mailbox

Would you do it like this or switch Blue and Green?
The ekey has to be on Red or would Blue still be an alternative for the ekey? (if the doorbell is not on Blue)

And why don't you install a system, for example, Gira 106 with everything: Ekey, doorbell, and video system?

Systems like [z.B. Gira 106] or [Siedle] are unfortunately way too expensive for us. Therefore, we first chose an affordable video doorbell; the [Ring] costs about €200 for the top model. Additionally, these systems also have many negative points. For example, we don't want a classic indoor station; the image should simply be streamed to our phones and, if applicable, to our existing [Echo Show] in the living room. Many people we know have had good experiences with the WLAN doorbells, and our electrician has confirmed this as well.

You don't have any children yet, do you?
