Underrated Feature: Camera Tilt/Rotation Markings

Looking at a Hikvision dome recently, I noticed they had added degrees rotation on the imager gimbal, making it really easy to answer the old "is this upside down or right side up?" question without having to use a monitor.

But I know of very few other cameras that do this, with most having a vague notch or mark at the top or bottom of the lens, if anything.

The Axis Q3709 has degree tilt marks, which is useful, as well, but I've never seen rotation marked like above.

Anyone know of others that use markings like this? It's a simple install feature that seems like it could save a few minutes compared to guessing at orientation and checking on a monitor.
