3.4 Analog video output

Please use the supplied adapter (2-pin / BNC)
for the use of the analog video output
(composite / CVBS, 1Vpp).
The analog video output is designed for
service purposes such as adjusting the lens.

3.5 Zoom and focus setting

1) First loosen the zoom and focus handle
(turn the handle counter-clockwise).
2) Then set the desired zoom factor and focus
point.
3) Then fix the zoom and focus handle by
turning the handle clockwise.

3.6 Notes to the usage of internal IR LEDs

The IR range is strongly dependent on the environmental conditions. If the area in the
camera's field of view reflects poorly or if there are no objects within the max.
illumination range, the brightness of the video image at night may be too low. This will
result in poor usability of the video image.
In addition, when installing the camera it must be ensured that no objects are located in
close proximity to the camera's field of view (e.g. roof gutter or wall). These objects can
reflect back the IR light, resulting in circular fading on the video image in the opposite
direction to the object.
The IR range might be reduced as well by strong absorbing surfaces (e.g. asphalt).
