31Appendix C — GlossaryAlarm ActionsThe assigned responses for the dome camera when inputs change from normal to abnormalstates. The dome may run a Preset, Pattern, or have no assigned action for each of the fourdome inputs. The dome may also send alarm states to the host controller for processing. Seealso Input and Normal Input State.AreasProgrammed 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 bedifferent sizes. Up to 16 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-offbetween picture level and noise may be adjusted when AGC is disabled.On-screen MenuThe text overlay menu system used for setting dome features. The utility is accessed using akeystroke combination. The utility provides settings for camera functions, zoom, alarms, textdisplay, and password protection.FlipAllows the dome to automatically turn 180 degrees when the camera tilts to its lower limit andstays in that position for a brief delay. When the dome flips (rotates), the camera starts movingupward as long as the tilt control is kept in the down position. Once the control is released, thetilt control returns to its normal operational mode. The flip feature is useful when you need totrack someone who walks directly beneath the dome and continues on the other side.Home PositionThe default position to which the dome camera returns after an assigned period of inactivitypasses. The default position may be a Preset, Tour, Pattern, or No Action.Input AlarmA connection point on the dome camera that enables the system to monitor Input Devices. Thereare four inputs available for the dome camera.Input DevicesExternal devices that provide information about the condition of system components thatconnect to the inputs on the dome camera. Typical input devices include door contacts, motiondetectors and smoke detectors.
