Have a look at the post at bottom of page 6 of this thread?I'm considering this camera for the backyard, by the patio sliding door.
I don't like the mounting options, offered by Dahua.
I'm looking at this mount on Amazon, and it seems like the diameter should accommodate the diameter of the camera.
