Recess for camera in external insulation

Hello,

I am currently in the process of completing my electrical planning / installation in the outdoor area.
My exterior wall consists of a 6cm thick wood fiberboard (complete wall construction from outside to inside: 6cm wood fiber, 20cm insulation wool 0.35, 1.5cm OSB, 6cm installation level with 6cm insulation wool 0.40, 1.5cm OSB & 1.25cm plasterboard).

I want to install a few cameras outdoors here (G5 Turret Ultra).
Now, the camera itself has a connection cable that needs to be stored somewhere + the network supply line with a connector coming from the house.
My first idea was to use a Kaiser Econ Iso + box and install the camera on it. But the diameter does not fit. The box is too big or the camera base is too small. You can see it anyway you want... I have not found another box for wood fiberboards yet.

Option 2 would be to use a conduit and try to connect the cable and push it back as far as possible. However, this is not 100% tight and air/moisture may possibly enter my installation level... Of course, there is still the option to foam and seal the conduit on the inside.

Option 3: Mill/drill a recess with a diameter of 3-4cm and a depth of 3cm (50% of the wood fiberboard), route the network cable from the inside there and have everything plastered normally. Then place the camera above it.

Do you see any problem with Option 3 that the insulation / wood fiberboard is weakened too much and a thermal bridge is created?
It wouldn’t be any different with the box anyway (or there is also a weakening with sockets etc.).

Regards

Why not use a Kaiser Universal/System device carrier? That is, either 1159-24 or 9966.21. They offer a mounting plate that can be plastered over, and if the built-in opening is too small or the system plates for [UP-Dosen] are too large, you can cut a larger/smaller opening in it. Inside, you then have more than enough space for cables and any terminal work, and everything is still insulated.

However, for all solutions, the sealing (moisture / airtightness) should already take place at the point where the cables exit the OSB board, with a suitable collar.

Hi ,
I use the universal device carriers (1159-24) for my "old building" which is insulated with 10cm stone wool. These parts are really practical here (screwed to the wall and then the insulation thickness can be adjusted variably).

In this specific case, however, it is only 6cm wood fiberboard and insulation behind it, i.e. nothing to screw into.
Or would you run the parts up to the OSB board (i.e. 6cm wood fiber 20cm clamping fleece) and screw against it there?

What I have now found is the universal installation housing (article no.: 1095-22).
That would actually exactly fulfill my purpose - but it is not insulated or airtight. No idea if that might be a problem again...

I could cut out the wood fiberboard accordingly and screw the housing horizontally.

Sure, let the device carriers pass through, due to the extensions they can, I believe, compensate up to 360 mm insulation thickness. This way you also have some leeway in the future if you want to attach something different there – of course, taking into account the permissible load for the cantilever.

As long as the wood fiberboard allows the lateral screwing, the solution with the 1095-22 is certainly conceivable – as mentioned, the sealing should be done behind the insulation anyway. In the flush-mounted box (however it is executed), there should be at most an additional sealing layer.

I have one general question:
Through my vapor barrier directly the cable or conduit with cable?
To my understanding, a conduit would always be a bridge through which moisture can pass...
But you see it so often!

OK... there are special sealing plugs for that case
