5.1 VG5 AutoDome Operation and Control 14

1 Camera Setup

Install and wire the 100 Series AutoDome according to the VG5 AutoDome Installation Manual. A typical system includes a keyboard, matrix switcher, monitor, and appropriate wiring connections. Please refer to the individual product manuals for complete installation and setup instructions for each of the system components.

1.1 Configuring the Camera

To assist setup, the VG5-100 Series camera module can be connected to a monitor through the miniature 2.5 mm monitor jack located on the camera circuit board. The monitor jack provides a composite video signal with synchronization. An optional cable (part number S1460) is available for making this connection.

To access the monitor jack, remove the bubble and covert liner:

1. Insert a small screw driver through the keyway in the Pendant trim-ring, rotate the dome bubble counterclockwise and remove the dome bubble. For In-Ceiling AutoDomes, you must loosen the small screw in the trim ring before rotating the bubble.

2. Press and hold the two retention buttons on each side of the camera module and then pull off the covert liner. See the image below.

Removing the covert liner provides access to the menu keys, and the pan and tilt thumbscrew adjustment locks.

2 Positioning the Camera

The camera module position can be adjusted along the horizontal, vertical, and diagonal (for azimuth) axes. When adjusting the position, ensure that the picture displayed on the monitor is level. After the covert liner is removed, position the camera by performing the following steps:

WARNING!

To prevent damage to the camera module do not rotate the camera past its stops.

1. For horizontal (pan) adjustment, loosen the thumbscrew at the platform base and rotate the camera (left or right) to the desired position. The camera can be rotated up to 360° between stops. If it hits the stop before achieving the desired position, rotate it in the opposite direction. Retighten the thumbscrew to secure the camera.
2. For vertical adjustment (tilt), loosen the thumbscrew at the tilt wheel and position the camera (up or down) to the desired position. The camera can be tilted up to 110^ between stops. Retighten the thumbscrew to secure the camera.
3. To compensate for angled ceilings or sidewall mounts, push the camera inward toward its base and rotate it until the image on the monitor is horizontal. The camera can be rotated up to 300^ between stops.

CAUTION!

The CCD image sensors are highly sensitive and require special care for proper performance and extended lifetime. Do not expose it to direct sunlight or bright spotlights in operating and non-operation conditions. Avoid bright lights in the field of view of the camera.
