Yes, deliberately. The cables are there, I can upgrade anytime, but even after 6 years there is still no need.
All trades are also connected to the bus, the obligatory poster recognition is also present, but in my opinion an intercom system is unnecessary, so there isn’t one.
Doorbell yes, but as already mentioned, if someone rings, you can see them anyway and I won’t open if I’m not home.
Who was there I see on the surveillance cameras if something happens or so.
The only problem is if you have a front door without glass or with frosted glass... then you are left with just ding dong...
Well, you have to decide that directly on site what you need. Every house and every entrance situation is different.
Alex and I have glass in the door for example... so you can see what’s going on...
