ᐅ Looking for a wireless intercom system with local power supply

Hello everyone,
I would like to install a mailbox with a doorbell and intercom at the entrance to our property, but I really don’t want to run any cables out there. My requirements are:
The distance in a straight line between the intercom and the FritzBox is about 35 m (115 feet), but the cabling route would be around 100 m (330 feet).
The second-best option would be to only run power there, moving the “doorbell mailbox” to the opposite side of the street, where it is somewhat less convenient.
Does anyone have any suggestions?
Thanks in advance!

- 3 doorbell buttons
- DECT connection for the intercom linked to the FritzBox
- local power supply (battery + solar panel)

WiFi with WPA2 is just as secure as Powerline.
MAC addresses can be easily changed, but first, you need to know which devices are allowed. No one stands outside a typical house just to hack the WiFi. The devices inside the LAN should also be secured. For example, I mentioned RADIUS as one option for additional security. Many devices support this. Once you have a NAS, you can set up a RADIUS server.
Hampshire wants a "simple" solution.
The only Powerline devices I know that are suitable for outdoor use are the hotspot from Bega / Devolo. That means placing a Devolo device inside near the router (e.g., a FritzBox) and connecting it there. Then, run powerline wiring to the doorbell system and plug the hotspot in there. If you only use the app, you could also use the guest network (LAN 4, activated in the settings) on the FritzBox for this purpose. This way, the LAN would also be protected. The benefit is having internet access in the garden or driveway. But for that price, you could also get enough CAT8 cable...

Sorry, what on earth do you want to do with CAT8 cables? Connect a data center to a masonry gate post or something?! The range is well under 100 meters, they’re a pain to install (bending radius), and you can’t really take advantage of the higher data transfer speeds because the connectors can’t be crimped by a private person and aren’t supported by most devices.
For a video camera, CAT5e is more than enough, it’s easy to install and very cheap. That would be my preference instead of some hastily done Wi-Fi solution.

I can tell you why. The cable length is estimated to be around 100 meters (330 feet).
When installing new cabling today, you would use CAT7 or even CAT8, depending on price and availability.
For a length of 100 meters (330 feet), I would especially pay attention to shielding. The goal isn’t to get a 10 Gbps connection all the way to the fence but to have a stable 1 Gbps or 100 Mbps connection.
When installing, there isn’t much difference between using CAT7 or CAT8 patch cables.
The connectors in this application are not really CAT8 anyway...

I have now decided on a wired solution, most likely Auerswald, as it is available at a low cost with three doorbell buttons and no camera, connecting via an a/b port.
Thank you very much for the advice.

Cat 8 is basically using a sledgehammer to crack a nut in private cases...
By the way, CAT8 officially has a maximum cable length of 30 meters (100 feet), which can be quickly exceeded in house construction.
Cat5e is more than sufficient here, as it is specified up to 100 meters (330 feet) and supports 1 Gbit/s. That is completely adequate.

I didn’t mean to suggest using CAT8. Cat 8 is generally better shielded by default. At the fence, it probably won’t be needed in the future either.
100 meters (or more) at 1 Gbps are easier to achieve with Cat 8 than with Cat 5e.
Anyone installing CAT cable today should go for 7 or 8.
But Hampshire has now found a solution for itself.
