Freeze Frame
A feature that allows the current image to be maintained on-screen when switching to a
preset or pattern. This function prevents the display of the dome movement and lens
adjustments while the preset or pattern position is sought. Once the preset or pattern is
ready for display, the image switches smoothly to the new scene. See
Preset and
Pattern.
Home Position The default position to which the dome returns after an assigned period of inactivity
passes. The default position may be a
Preset , Pattern , or No Action .
Input
A connection point on the dome that enables the system to monitor Input Devices . There
are four inputs available for the dome.
Input Devices
External devices that provide information about the condition of system components
connected to the inputs on the dome. Typical input devices include door contacts,
motion detectors and smoke detectors.
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 .
Preset
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to
96 presets may be programmed for the dome. For domes running in a Manchester
network, only 64 presets may be programmed. See also
