Set north. The Set north button programs the north (0°) pan point for the camera.
Note: When using bearings for your pan coordinates, they are easier to interpret if you set the true due north point
as the 0° point. If, however, you are using degree pan coordinates, you can set the 0° point anywhere along the
scale. For example, you may want the 0° point to be a main entrance of a facility.
To program the north point:
1. Select Set north . The programming interface will be replaced by live video that asks you to
aim the camera to the due north point.
2. At the live video screen, use the joystick to pan the camera to the desired position.
3. Press the iris + or the set ( ) key on the keypad to save the north point or press the iris - or
esc key to cancel the north point. Both canceling and saving the north point returns you to the
Coordinates page of the Preferences page.
