ᐅ Looking for a wireless intercom system with local power supply

Or you can use, for example, a Doorbird D2103V (Wi-Fi).

Thanks for the Doorbird tip – that would be like using a sledgehammer to crack a nut for me – I definitely don’t need a camera or access chip. However, Wi-Fi connectivity is appealing.

But please test the connection first at 35 meters (115 feet) with walls in between. The 2.4 GHz network experiences a lot of interference from other wireless networks. That’s why I didn’t mention it. Besides, I wouldn’t want the doorbell and door opener connected to the cloud...

I understand that the Doorbird can also operate without internet, but some functions would not be available.

It is only one wall made of wood. I prefer a different material than you, Rick.

By the way, if you want to see beautiful concrete, I recommend a visit to the Langen Foundation. The Japanese architect Ando is famous for his smooth concrete. To my knowledge, this is his only building in Europe. It is located near Neuss.

The second-best solution would be to run only electricity there,

If that is acceptable for you, I even have a proposed solution. Look up TP Link, powerline adapters, and similar devices. They transmit the network signal over the electrical wiring. So you plug a device into a socket at one end, which you can also connect to a LAN cable. At the other end, where the electrical wiring ends, you plug the same type of adapter into the outlet, allowing you to tap the signal again via LAN cable. You get both electricity AND a network signal. These adapters are also available with Wi-Fi, but I find LAN to be better.

Apart from the fact that Wi-Fi outdoors can be even more easily intercepted than inside your apartment, the data transfer rate with LAN is simply much higher. This also makes video transmission easier (for example, a doorbell with a camera). Even without a camera, I would recommend focusing on a high data transfer rate for better voice quality. Maybe you have already experienced how well IP telephony works with a poor data connection (you can test this with Skype).

I would advise against the idea of trying to pick up the Wi-Fi signal from the house over a distance of 35 meters (115 feet). Try testing with your phone how good the signal and data transfer rate are when you are 35 meters (115 feet) away from the house... This is not a stable solution.
