>>430238220The camera was a D-link HD network camera, with only a wired connection. I chose that because of the various problems that wireless always has.
Its a medium sized camera, so there was only one good way to hide it. I purchased a full-length mirror, except it was a "two-way" mirror.
I drilled a hole in the wall to mount the camera, hooked it to a powerline networking adapter, and hard-wired the powerline adapter to the electrical wiring inside the wall.
Mounted the camera in the drilled hole, and then put up the mirror. You can't see through the mirror and it looks completely normal, but the camera can see through looking the other way just fine.
