Is a TV wall mount stable on a brick wall?

Alright! Thank you all! Yes, that's in the basement. However, the wall was only built afterwards because the construction company made a completely idiotic 160sqm room out of the basement. Now we're off to the hardware store. Thank you :)

From my point of view, there are 2 criteria that are important:

1. Does the wall hold?
2. Does the anchor hold?

1.
With a masonry wall, I basically have no worries, no matter what it is made of. If the anchor is secure, the wall holds.

2.
Anchors hold very differently depending on what the wall is made of and how they work.
The safest method in my experience is: drill a hole and glue in threaded rods.
The adhesive material for this is often quite expensive.
My previous tests have shown that even cheap adhesives hold well enough.

The wall was only added later during construction because the construction company turned the basement into a completely idiotic 160 sqm room.

What year of construction is the wall anyway? I don't want to rule out bricks, but it could also be KS. 2DF in pure stretcher bond, so apparently only one header thick, to my irritation without mortar joints ... unusual.

I think it looks pretty clearly like aerated concrete ... (but I am not a mason)

I think it clearly looks like aerated concrete ...

I just forgot aerated concrete in the list, but I don’t see anything “clear” about it. KS is rarely whitewashed additionally, with aerated concrete a coat of paint is common, but that would be expected to look more coarse-pored – but we’re not on site and the OP is probably not a photographer.

As a non-building bystander, the size seems to speak against sand-lime bricks to me. That the vertical joints were not mortared makes me assume that they have the typical connections for aerated concrete blocks ...

but I admit: I don't know o_O
