ᐅ Looking for a wireless intercom system with local power supply

If that is acceptable for you, I even have a suggested solution. Try searching for TP Link, powerline adapters, and so on.

I am currently using such devices in my house, and they work quite well. However, they are not very suitable for outdoor use.

Aside from the fact that Wi-Fi outdoors is even more vulnerable to interference than inside your apartment, the data transfer rate over a wired LAN is simply much higher.

You are absolutely right. Somehow, I don’t quite believe there isn’t a low-end DECT solution. It will probably come down to pulling cables, and at that point, it’s no extra effort to lay a data cable alongside.

Could you briefly explain why they are not very suitable for outdoor use? I only have experience with indoor use from earlier times, but they work just as well for me as they do for you.

Alternatively, I just saw a directional antenna on EBAY for 650 EUR. You need to compare the investment cost with buying a microwave link, which you would then no longer need. And you can communicate wirelessly with your outdoor unit.

1. I don’t trust these devices to be weather-resistant, and
2. I consider the ventilated open construction highly attractive to crawling insects seeking warmth.

Microwave link? I prefer low-end options.
I would rather get an old FFOBZB, but even then I would need cables again.

If power is drawn, the data cable should be installed at the same time without much additional effort.
Powerline adapters are a (poor) retrofit solution and will never achieve the speed and reliability of a true LAN.
Radio link is not necessary for something like this. An outdoor access point is sufficient. Since the cable would then be outside, it makes sense to lay it for the remaining meters as well.
Anyone recommending powerline should not talk about capturing data over Wi-Fi. A good Wi-Fi setup (e.g., radius authentication with certificates, separate network, MAC address filtering, no new devices allowed…) is significantly more secure.
With powerline, it depends on the situation. Sometimes neighbors also have signals...

@hampshire thanks for the tip about Ando.
I have to admit that I’m not very knowledgeable about architecture. More the type “I like this, I like that less.” Your wooden house and the one from @Climbee really appeal to me. They simply radiate warmth and coziness. I’ve always wanted a cubist style with concrete. Inside, there will also be some (walnut) elements.
Your wooden wall also dampens the Wi-Fi signal quite a bit. Especially since you probably also have insulation, vapor barrier, or something similar.

Sorry, but it seems you didn’t fully understand either the question or my answer. Part of the question was: "The second-best solution would be to install power ONLY," so based on that premise I explained how data can be transmitted using the power lines. Of course, a 1000 Mbit (1000 Mbps) connection is better than Powerline networking, but that wasn’t within the preferred solution scope mentioned in the question.

I don’t want to start a side discussion about Wi-Fi here, but RADIUS is mostly used in business environments and is not supported by a standard consumer modem-router. However, if you have a RADIUS server set up and can configure and manage it, then sure, why not.

The suggestion of using point-to-point wireless for a 35-meter (115 feet) distance was a JOKE!!! I almost expected that this technology would not be needed for such a short distance.

Regarding MAC address filtering and not allowing new devices: That’s just a command line away from spoofing any MAC address (which I can identify in advance by monitoring your devices). So, even devices that are already allowed can be impersonated. Not to mention other attack scenarios. If someone wants to set up Wi-Fi outdoors, they can do so. I just advised the original poster based on my personal experience. Especially if this is linked to door intercom systems that also unlock doors or gates, etc.

You are right, I said that only electricity was the second-best option. Thanks for the suggestion, powerline could be an option—I would look for outdoor-rated devices.
