Corner Security Cameras

I am trying to find a decent solution for a pair of hidden cameras to go in a client’s house. Most of the cameras I have taken care of already, but for their main living space, they don’t want to see the cameras and want a fairly good FOV of the room.

I need to mount the two hidden cameras I’ve found (Hikvision DS-2CD6425G1-30 covert cameras) directly into the corners of both rooms. However, this will still leave a visible black dot in the corner, which the client does not want.

Does anyone have a solution for this? I considered trying to find some sort of corner one-way mirror mount and putting a white mesh over the mirror but couldn’t find anything like what I was looking for.

Any help would be appreciated!

Edit #1: No, this is not for an Airbnb. They are just some very rich clients who have specific tastes and don’t want their home design thrown off by cameras in their hosting area.
