Video Drive (VSD) Lens
Set the VSD/DC switch on the rear of the camera (see
Figure 3 ) to VSD.
Backlight Compensation (BLC)
If there is excessive light (for example, a window exists in a
scene), the camera tries to compensate by reducing the
overall exposure, resulting in the areas surrounding the
window becoming too dark. Turn the BLC switch ON to
eliminate the silhouette effect.
Automatic Gain Control (AGC)
This feature can improve picture quality when the level of
scene illumination is low. When set to OFF, the maximum
gain is 11 dB. When set to ON, the maximum gain is 30 dB.
Synchronization Selection (LL/INT)
This switch selects the synchronization mode of the
camera. When the camera is connected to an AC supply,
the Line lock (LL) mode is used to lock the camera’s frame
rate to the frequency so that each camera in the system is
triggered at the same point on the supply’s AC cycle. The
default setting is LL.
WARNING! The LL/INT switch must be set to INT
when operating from 12 VDC.
