Glossary G-3
Input Devices
External devices that provide information about the condition of system components that
connect to the inputs on the dome. Typical input devices include door contacts, motion
detectors and smoke detectors.
IR Mode
A feature of the camera that permits manual or automatic switching between color and IR
(black-and-white) operation. When IR mode is active, clearer images may be obtained under
low-light conditions.
Line Lock
Allows you to phase lock the video with the AC power line. When line lock is enabled, it
prevents vertical video rolling when switching multiple cameras to a single monitor. If text
appears slightly tinted on color monitors, disabling the line lock may prevent this problem.
Name Information
Relates to the display the dome name, the area where the dome is pointing, the name of the
preset or pattern that is running, and alarm names. The display of each type of name setting
can be enabled or disabled. When the display of camera or area names is enabled, the
information appears on the screen continuously. Preset, pattern, and alarm names appear only
while they are active.
Normal Input State
Describes the expected state of a device connected to one of four dome inputs. The normal
state may be open or closed. When a device is not in its normal input state, an alarm is
issued. Transmitting the dome input states to the host controller is not supported with
Manchester.
North Position
User-definable setting that may correspond to magnetic north or some well-known landmark.
Used to approximate the camera dome's pointing direction when Direction Indicators are
enabled.
Open Shutter
Setting used to improve the quality of video obtained in extreme low-light situations. When
the Open Shutter setting is enabled, low-light information is collected over multiple fields
based on the Shutter Limit setting. As a result, video may appear blurred or choppy in
extreme low-light situations. This setting does not effect camera operation in normal lighting
situations. See also Automatic Gain Control (AGC).
Password Protection
Prevents unauthorized users from starting the Configuration Utility. The password may be
from 1 to 8 characters long.
Pattern
A series of pan, tilt, zoom and focus movements from a single programmable dome. Up to 3
patterns may be programmed for the dome.
Peel
Button found on some controllers that initiates the Apple Peel pattern.
See Apple Peel Pattern.
