Backlight Compensation; Agc Low / Agc High; Synchronization Selection (Ll/Int); Line Lock Phase Adjustment Potentiometer - Honeywell E Serie Installationsanleitung

Backlight Compensation

If a strong background light such as a window exists in a scene, the camera
tries to compensate by reducing the overall exposure. This means that areas
surrounding the window become too dark. Set the backlight compensation
(BLC) to ON to eliminate the effect of an area of strong background lighting
in a scene. The default setting is BLC OFF.
BLC will only function with a manual iris lens when the Electronic Iris feature
is switched on. For Direct Drive and Video drive lenses, BLC will function
even though the Electronic Iris feature is switched off.

AGC Low / AGC High

The Automatic Gain Control feature can improve picture quality when the
level of scene illumination is low. For most applications, select:
LOW AGC for 18 dB gain
HIGH AGC for 38 dB gain

Synchronization Selection (LL/INT)

This switch is used to select the synchronisation mode of the camera. When
the camera is connected to an AC supply (either Mains or 24V Low Voltage),
the Line-lock (LL) mode can be used to lock the camera's frame rate to the
mains frequency so that each camera in the system is triggered at the same
point on the supply's AC-cycle. See also
Potentiometer. The default setting is LL.
WARNING! The LL/INT switch must be set to INT when
operating from 12 VDC.

Line Lock Phase Adjustment Potentiometer

When the camera is in Line-lock mode it is possible to adjust the point on the
AC cycle at which the camera triggers. This facility is provided so that
cameras that are connected to different mains phases may still be
synchronized.
