CONTROLS AND SETTINGS

1. Backlight compensation: subjects will appear dark and hardly visible if lit by a strong light from the
back. Position dip-switch BLC to BLC to compensate for this problem.
2. Automatic exposure control: position dip-switch ES to ES to automatically vary the electronic shutter
speed according to the light conditions in the environment.
Note: Use of automatic electronic shutter speed control may cause flickering of the image when a
source of fluorescent light is framed.
DO NOT USE THIS FUNCTION WITH AUTO-IRIS LENSES.
3. Automatic gain control: use the automatic gain control (dip-switch AGC to position AGC) to ensure
sharp pictures in medium-to-low light conditions.
4. Auto-Iris controls: DC/VIDEO driver switch can be used to select two types of lenses:
•
DC driver lenses (without amplifier): position switch to DC; use the camera LEVEL settings to
obtain a clear, sharp picture, if required.
•
VIDEO driver lenses (with amplifier): position switch to VIDEO; use the camera LEVEL and lens
ALC settings to obtain a clear, sharp picture, if required.
Note: These adjustments are usually made by the manufacturer and need not be modified.
When using an Auto-Iris lens, the automatic exposure control switch (ES) must be set on NOR.
5. Line Lock/Int Sync: in a multi-camera system, all incoming video signals must be in synchronism or
mixing and switching between cameras will cause frame roll. By setting the dip switch INT/LL to LL
position, the camera will synchronize with the mains frequency. Thanks to this feature cameras using
the same power supply line can be synchronized with one another. Also you can adjust the V-PHASE
to let every camera be in phase. For those who want to let camera be in Int Sync mode, just set dip
switch to INT position.
6. The NC switch doesn't effect the camera performances.
