7.8 Azimuth, Elevation, and Compass Directions
The VG5 AutoDome allows a user to display the azimuth and elevation position, and the
compass heading of the camera. The AutoDome displays the position data in the lower-right
corner of the image display. These readings are described as:
The AutoDome uses the azimuth to determine the compass direction. The following table
shows the azimuth range and its corresponding compass heading:
7.8.1 Setting the Azimuth Zero Point
The installer must calibrate the Azimuth Zero point. The AutoDome uses the Azimuth Zero
point, usually set to magnetic North, as the zero degree pan position and as the North
compass heading. The AutoDome then displays the azimuth reading and the compass heading
based on the number of degrees from the Azimuth Zero point.
To set the Azimuth Zero point:
1. Determine the North compass heading, then move the camera to that position.
2. Press OFF-90-ENTER to turn off the command lock (if active).
3. Press ON-94-ENTER to set the Azimuth Zero point.
Azimuth: The pan angle from zero to 359 degrees in one degree increments. An azimuth
of zero degrees corresponds to North.
Elevation: The tilt position from zero (horizon) to –90 degrees (camera pointing straight
down) in one degree increments.
Compass: The cardinal or intercardinal (N, NE, E, SE, S, SW, W, NW) heading in which the
camera is pointing.
Azimuth Range Compass Direction
21° to 65° NE (Northeast)
66° to 110° E (East)
111° to 155° SE (Southeast)
156° to 200° S (South)
201° to 245° SW (Southwest)
246° to 290° W (West)
291° to 335° NW (Northwest)
336° to 20° N (North)
CAUTION!
Bosch recommends that only the installer calibrate the Azimuth Zero point. A recalibration to
the Azimuth Zero point may cause inaccurate compass headings.
