Camera Settings
Entering the Menu
The two buttons marked A and B that are situated below the camera lens are used to set the
camera. Press these buttons to access and navigate the on screen menu as follows:
• To access the menu system, press A momentarily.
• To cycle through the menu items, press A repeatedly.
• To change the setting in the selected menu item or go to a supplementary menu
page, press B.
• To save your settings, select Save and Exit and press B. Note that settings will be
saved when the menu times out.
Adjusting the Picture Settings
In most situations, the default settings give good quality results. However, in specific circumstances,
the following adjustments may improve performance.
Use the direction buttons to navigate the menu, and to select parameters.
Exiting the Menu System
The menu system can be exited by selecting SAVE AND EXIT with the up/down menu buttons and
then pressing the Enter button. Any changes made while within the menu system will be saved. The
menu system will be automatically exited if a key is not pressed for 2 minutes.
Exposure
Hi is intended for general usage including brightly lit outdoor scenes and indoor scenes which
contain a view outdoors. It maintains optimum contrast in the darker portions of a wide dynamic
scene.
Lo(w) may be used for indoor scenes, where the contrast between the brightest and darkest parts of
the picture is low. It maintains optimum contrast in the brighter portions of a wide dynamic scene.
AGC
This affects the way in which the camera displays scenes with lower illumination levels.
DnR gives the optimum performance for stationary or slow moving objects. DnR is a Digital Noise
Reduction system that reduce AGC noise by means of a field integration algorithm. A consequence
of DNR is that moving objects can appear blurred at very low light levels. This setting has a
maximum gain of 24dB.
Motion provides a clear image of moving objects but may introduce noise into the darker parts of
the picture. This setting does not use DNR at high gain. The images are sharper than DNR but the
visible gain in the image is greater. This setting has a maximum gain of 24dB.
Low is less sensitive at low light levels and provides a relatively noise free picture. Setting the
AGC to LOW reduces the camera’s performance at low light, but improves image quality in bright
conditions. This is the preferred setting for well-lit scenes. This setting limits the gain to 7dB.
White Balance Range
With some street lighting, for example sodium or mercury lamps, the camera may show an overall
colour hue instead of white. In these situations, setting the White Balance Range to Wide corrects
the white balance.
PRO (default)
This setting limits the white balance range to 2800 - 6500K. This provides a more accurate colour
rendition.
WIDE
This setting extends the white balance range to 2500 - 9500K
