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.

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.

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).
