Revo REHVDPTZ22-1 INSTRUCTION MANUAL - Manual (Page 81)

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.
On-screen Menu
The text overlay menu system used for setting dome features. The utility is accessed using a
keystroke combination. The utility provides settings for camera functions, zoom, alarm, text
display, and password protection.
Flip
Allows the dome to automatically turn 180 degrees when the camera tilts to its lower limit and
stays in that position for a brief delay. When the dome flips (rotates), the camera starts moving
upward as long as the tilt control is kept in the down position. Once the control is released, the tilt
control returns to its normal operational mode. The flip feature is useful when you need to track
someone who walks directly beneath the dome and continues on the other side.
Home Position
The default position to which the dome camera returns after an assigned period of inactivity
passes. The default position may be a Preset, Tour, Pattern, or No Action.
Input Alarm
A connection point on the dome camera that enables the system to monitor Input Devices. There
is 1 input available for the dome camera.
Input Device
External devices that provide information about the condition of system components that connect
to the input on the dome camera. 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.
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 name. 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 dome camera’s input. The normal state
may be open or closed. When a device is not in its normal input state, an alarm is issued.
