DIP switch settings
The bank of dip switches allow the following settings to be made:
SDN mode (SDN / ON)
When ON the camera operates in monochrome mode in reduced
lighting.
Auto White Balance (AWB / AWB.EX)
AWB: The camera operates in the normal Auto White Balance range
2700K~11000K.
AWB EX: The camera runs in the extended Auto White Balance
range 2000K~18000K.
Line Lock (INT / LL)
In LL mode, the V-Phase may be adjusted to compensate for
connected supply phase differences.
Only applicable for 24VAC supply - otherwise the camera operates
with INTernal sync.
Flicker less mode (FL / ON)
ON: The Camera reduces flicker in the image under fluorescent
lighting.
Back Light Compensation (BLC)
When set ON, this option improves the camera response to strong,
unwanted lighting effects behind the required subject.
Low Light Sensitivity (AGC-EX)
When set to EX sensitivity in low light is increased.
Focus & view angle adjustment
Twist the levers on the side of the varifocal camera to adjust the
focus and view angle settings.
TIP: If necessary, perform the final focus through the dome cover.
Hold it to the lens reversed to confirm the final results.
Vertical phase adjustment
Use this adjustment when using an AC supply to align the camera
phase with that of the supply.
Iris adjustment
This is factory set and should not normally require adjustment
except to compensate for excessive image blooming.
