Video-Ait-Sytem
Check all settings on a correctly adjusted monitor.
If the mechanical iris is closed more than necessary, the
IVS will compensate by increasing the gain and restore
the image brightness electronically. This creates additional
electronic noise. To avoid this, open the mechanical iris.
• To change the iris, turn the wheel with the iris symbol Õ.
10.3.3 Alignment of the image position
(X, Y and Rotation) and focus
The position of the image on the CCD Chip and its focus can
vary slightly from camera to camera. The video image on the
monitor may appear off-centre, not levelled or out of focus.
All adjustments can be made by using a 1,5 mm Allen key,
which is delivered with the IVS.
Do not use force!
• Image position adjustments in x and y direction can be
made with the adjustment screws marked x and y aphoto.
• The screw marked Ò moves the video image horizontally
on the monitor. The screw marked Ó moves it vertically.
Note: Design restrictions imposed by the IVS‘ small
size mean that the direction of movement
imparted by the x and y adjustment screws
might be not precisely in the x and y directions.
• Image rotation can be adjusted by the screw marked
with the Ô symbol aphoto.
• The image can be focussed using the screw which is
marked with the F symbol aphoto.
