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 title(name) is enabled, the 
information appears on the screen continuously. Preset, tour and pattern titles(names) appear 
only while they are active. 
 
Normal Input State 
Describes the expected state of a device connected to one of eight dome camera’s inputs. The 
normal state may be open or closed. When a device is not in its normal input state, an alarm is 
issued.  
 
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. 
 
Low Shutter 
Setting used to improve the quality of video obtained in extreme low-light situations. When the 
Low 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). 
 
Pattern 
A series of pan, tilt, zoom and focus movements from a single programmable dome. Up to 8 
patterns may be programmed for the dome camera. 
 
Preset 
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to 240 
presets may be programmed for the dome camera.
