Appendix B — Troubleshooting
If problems occur, verify the installation of the camera with the instructions in this manual and
with other operating equipment. Isolate the problem to the specific piece of equipment in the
system and refer to the equipment manual for further information.
Problem Possible Solution
No video.
Verify that power is connected to all pieces of
equipment in the system.
Verify that the power switches are in the ON position.
Check the video connections.
Poor video quality.
Check that the BNC connectors are inserted properly.
Check the voltage level of the dome camera.
Cable for video is shielded.
Dome cameras lose their positions.
Reset the cameras using the Dome configuration
menus.
Check that the dome cameras are inserted properly in
the base.

Appendix C — Glossary
Alarm Action
The assigned responses for the dome camera when input change from normal to abnormal
states. The dome may run a Preset, Pattern, or have no assigned action for 4 dome inputs. The
dome may also send alarm state to the host controller for processing. See also Input Alarm and
Normal Input State.
Area
Programmed start and end points of the dome's field of view around its pan axis.
Each area is a part of a circular viewing area that extends around the dome. The areas can be
different sizes. Up to 8 areas can be programmed for the dome.
Automatic Gain Control (AGC)
Allows for the amplification of the video signal in scenes with minimal ambient light. Many low-
light scenes result in picture noise. As gain is increased, the picture noise is also amplified. When
AGC is enabled, the value of the gain setting is based on feedback from the camera. When AGC
is disabled, the camera uses the value set for the manual gain setting. The trade-off between
picture level and noise may be adjusted when AGC is disabled.
