Operation Manual
Camera Adjustment and Programming
With the exception of the focus and field of view adjustments (made
using levers A and B) all settings for the ZC-DWT4039 series camera
are made using its on screen menu display. A working video monitor
and a separate plug-in control board (C,G) are required to view and
select options.
Within the dome enclosure, attach the Control Board connector to the
socket (D) at the top of the service jack interface board (Type A), or on
the socket (H) on the gimbals disk (Type B). Ensure that the OSD lead
(F) is connected between the middle socket of the smaller circuit board
and the camera.
With power applied to the camera and a video monitor connected,
press and hold the ENTER key for three seconds to access the top
level menu. A map of the menu options are shown below.
To navigate through the menus, use the arrow keys on the control
board and use the ENTER key the “SAVE SETTINGS” option in the
“SAVE/RESTORE” menu. Otherwise any changes made will be lost
when the camera is next reset or has its power cycled.
Menu Description
PRESETS
These are "factory-set" general configurations. Select from the
preconfigured camera modes for the best performance in the specified
environment. Pressing the ENTER key on the selected option will
display the pre-configured set-up parameters.
NORMAL - This should provide the most versatile settings for general
purpose applications.
INDOOR or OUTDOOR - These settings are optimized for
indoor/outdoor lighting conditions.
FLUOR1 - Line lock recommended.
INT 1 - Internally generated sync.
LL - Line lock - sync is locked to the AC supply cycle and permits
adjustment of V-phase to correct vertical sync picture roll. (Applicable
for 24 V AC supply only. If a 12 V DC power supply is used, then the
camera will run in INT1 or INT2.)
INT 2 - Internal flicker less - Internally generated sync that can reduce
flicker under florescent lighting.
FLUOR2 - DC IRIS recommended.
EXPOSURE
EXPOSE MODE has 4 Exposure modes for selection. Each Exposure
mode uses the electronic shutter differently and is suitable for a
specific environment.
AGC - Automatic gain control - When low light priority is set to gain,
gain increases as light decreases up to the maximum set using gain
limit. No color artifacts are visible nor does the dynamic range
decrease as gain increases.
WDR RANGE CTRL - Use WDR control, electronic shutter control,
mechanical iris control, and the low brightness zone controls selected
in LOW Lux MODE to automatically control the exposure time.
Seamless switching between control zones delivers shockless AE.
**Requires a separate mechanical lens.
AE PREFs - Automatically optimizes the scene for highlights or for
shadows.
SHUTTER LIMIT - Limits the shutter value.
WHITE BALANCE
WHITE BALANCE has 4 modes for selection. Each mode uses the
electronic shutter differently and is suitable for a specific environment.
ATW Xtnd - Extended auto white balance range - use this setting for
scenes that may have an extremely wide range of color temperatures.
ATW Normal - Selects a normal auto white balance range for general
operation. If necessary, the range is configurable with low limit (to help
with reds) and high limit (to help with blues) adjustments.
AWB - Save or cancel AWB and all changes.
MANUAL - Allows manual setting of the image's color temperature.
This can be achieved by using the Kelvin option, by the method
familiar to the installer. This setting is also good for static environment
applications where the lighting conditions never change, such as in
indoor hallways.
VIEWING
MIRROR - This mode reverses the top and bottom sides of the linear.
GAMMA MODE - Select appropriate gamma mode for type of display.
Gamma correction compensates for a non linear grayscale in a display
device or to create non-standard luminance.
MANUAL - Manual Gamma may be used to enhance detail in low light
areas of an image which would normally not be visible with highlights
present in the image.
SHARPNESS - Adjusts overall image sharpness.
SATURATION - Adjusts overall color content of the image.
SETUP
IRIS- DC GAIN - Adjusts the iris control gain when using a DC iris.
AI THRESH - Adjusts the threshold at which the automatic iris
becomes active.
DAY/NIGHT SETUP - Day/Night operation. This feature may be used
to improve low light performance by reducing noise from the video
signal or force the camera into night mode regardless of lighting
conditions.
SAVE/RESTORE
RESTORE USER SETTINGS - This will undo any changes made
since the last time the settings were saved.
SAVE USER SETTINGS - Save any programming changes to ensure
they are retained after power loss or reset. If changes are not saved,
the camera will revert to the previous settings on power-up.
RESTORE FACTORY SETTINGS - Restore camera settings to factory
default - full reset, all previous programming will be lost including the
video standard, which will default to NTSC.
RESET CAMERA - This is a soft reset and has the same effect as
cycling the camera power.
SYSTEM INFO - Displays the camera firmware version.
