1.1.1 W B
HITE ALANCE
ATW mode (default)
In the ATW mode, the colour temperature is being monitored continuously, and the white balance is set
automatically by an internal micro-controller. The operating colour temperature range is
from 2500 to 9500 K.
AWB mode
When the switch is set to AWB (conventional white balance), a camera using white as its reference
automatically adjusts the content of blue and red in the picture, depending on the scene, to provide a
picture with balanced colour content. If the colour temperature of the scene is continuously changing, the
camera can lose its colour reference; in this case, switch the camera to ATW.
1.1.2 B
ACKLIGHT
This auto BLC is a digital light-level control system. It is activated automatically by screen histogram
(contrast) and 225-area window weighting integration. This controls iris gain and white balance
simultaneously so that a clear object with adequate light level can be optimised.
Central Window Weighted Average Backlight Compensation
This method is ideal when the main subject is fixed within the screen.
Histogram Backlight Compensation
This method is ideal when the main subject moves within the screen.
The combination of two types of backlighting makes it easier to arrange backlight compensation
operation to match the imaging conditions and installation location.
Note:
Compensation might be insufficient when the background is extremely bright.
1.1.3 G C
AMMA
Gamma correction is an electronic correction within the camera circuitry that matches the brightness
level seen by the camera with the brightness level displayed on the monitor. This adjustment enables the
monitor to display the correct level of contrast. The standard setting is .45 (default). The manual switch
should be used only if the controls on the monitor are not giving sufficient adjustment.
1.1.4 S
YNCHRONISATION
Line-Lock (external) (default)
The sync pulses are referenced to the supply frequency. The phase adjust buttons are used to
synchronise cameras even when they are connected to different phases of the mains supply, which
results in roll-free pictures
Internal
An internal sync generator is used when the camera is being powered off of 12 VDC.
1.1.5 A /M
UTO ANUAL
In auto mode, the camera automatically switches from colour mode to black and white mode as light
decreases. In manual mode, you can manually switch the camera from daytime colour mode to nighttime
B/W mode using the Day/Night switch (see section 1.1.6).
1.1.6 D /N
AY IGHT
When the AUTO/MANUAL switch is set to manual, the camera can be switched manually from daytime
colour mode to nighttime B/W mode.
