7.8Azimuth, 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:

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.

The AutoDome uses the azimuth to determine the compass direction. The following table shows the azimuth range and its corresponding compass heading:

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)

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-ENTERto turn off the command lock (if active).
	3.	Press ON-94-ENTERto set the Azimuth Zero point.

CAUTION!

Bosch recommends that only the installer calibrate the Azimuth Zero point. A recalibration to the Azimuth Zero point may cause inaccurate compass headings.
