Power line frequency: Set the power line frequency consistent with local utility settings to eliminate
image flickering associated with fluorescent lights. Note that after the power line frequency is
changed, you must disconnect and reconnect the power cord of the Network Camera in order for
the new setting to take effect.
Video orientation:
Flip - vertically reect the display of the live video;
Mirror - horizontally reect the display of the live video. Select both options if the Network Camera
is installed upside-down (e.g., on the ceiling) to correct the image orientation. Please note that if
you have preset locations, those locations will be cleared after ip/mirror setting.

The camera may be installed on a vertical, side-facing, or tilted surface in order to accommodate
the interior or exterior design of a vehicle. Because the interior of a transportation vehicle is often
shaped as a narrow rectangular space, the conventional HD image, such as that of a 16:9 aspect
ratio, will be incongruous with its wide horizontal view. With video rotation, the camera can more
readily cover the eld of view on a vehicle.
In addition to video rotation, if the camera is mounted on a tilted surface, you can:
1. Loosen the retention screw.
2. Rotate the lens module to adapt to the mount position. When done, fasten the retention screw.

The rotation here indicates clockwise
rotation. Rotation can be applied with
flip, mirror, and physical lens rotation
(see below) settings to adapt to different
mounting locations.
