If you install a panasonci WV-SW352 in a ceiling mount there is no way to flip the image via the software. Instead you need to take the cover off and then take the little black housing off, it just pops off, you don’t even need to loosen the screws and then rotate the back of the camera. Be careful not to touch the focus as that is not a manual operation.
To focus the camera go to the camera web page, click on setup, type in the default username: admin the default password: 12345 then click Image/Audio on the left and then click the Image/Privacy Tab, at the bottom there is a Focus line, push the Setup button on that line a new window should appear unless it was blocked by a popup blocker, on the Auto focus line click execute.
