Planning network cabinet and home server

Thanks for the food for thought :)
We already had a consultation with the police and received advice on all parts of the house, including the lighting of the property and also cameras.

Very good approach;
Also ask yourselves the question:
What happens if you see the burglar on the camera?

Which access points for outdoor use can you recommend? Where is the best place to position it? The terrace wraps around the corner.

I convinced my wife that we should get an access point on the terrace. I'll lay the cable tomorrow. It was a good argument that she can probably do home office on the terrace with her laptop then.

Ubiquiti UniFi AC MESH -> UAP-AC-M POE injector as well as wall mount included. Software controller installed on PC / notebook (don't forget backups) You only need to come up with something for the transition between the installation cable and the patch cable to the access point (deep box outside?) I used a small electrical distribution box and stored everything inside it. It is also visually inconspicuous in the bike shed.

Oh, do I really not need a mesh as an interim solution for that?

I thought the device is as small and flat as a light switch

This now somewhat exceeds the scope and may be unnecessarily paranoid, but I personally also recommend RADIUS authentication for the switch ports that lead outside to the APs. Most managed switches support at least a simple form of this. If you buy a 24-port switch, it probably supports that as well. Otherwise, just take a look at the data sheet. The manual usually explains how to configure it. This ensures that no device other than the access point can be connected to the network cable. Otherwise, anyone could plug the cable into their computer and compromise your network. However, someone would have to enter your garden and dismantle the access point for that to happen. An unlikely scenario, but the possibility exists. We will implement this since we have routed several LAN cables outside (doorbell, access point, wallbox, garden shed, etc.).

Radius is really almost too much. ;) But mac filter and closed firewall for these ports should definitely be in place if cables run outside the house
