On the BRC64 PC-NVR, you can use the mouse or the software control panel to perform the
PTZ (pan, tilt, zoom) operations. For the mouse-based PTZ control, the drag operation of the
mouse changes the viewing direction, and the mouse wheel does the zoom-in and zoom-out
of the image.
The result of the PTZ operation depends on where the camera is installed (on the ceiling, on
the ground, or on the wall). For the BRC64 PC-NVR to know the actual position of the camera,
please right click on the FishEye / Immervision A0**V / Immervision A8TRT camera image for
the menu to pop up. Then select Image Effect  Panorama  Camera Position. Under
Camera Position, 3 options are available: Ceiling, Ground, Wall.
Ceiling Select this option if the camera is installed on the ceiling
facing the ground.
Ground Select this option if the camera is installed on the ground
facing the ceiling.
Wall Select this option if the camera is installed on the wall
facing forward.
