11.2 Software Update

Installation of the software is carried out principally as Windows® XP Administrator.

11.3 Troubleshooting

The following malfunctions are to be fixed if applicable:

– Backlighting:

If backlighting effects are identified during recording, the light source must be covered

up, for example using curtains over windows or lampshades on lighting; alternatively, the

location of the camera should be changed.

– Reflections:

If the optical room monitoring system is enclosed in bulletproof or toughened glass, the

lighting conditions may cause reflections. These become stronger as the degree of light

within the glass enclosure increases. Such reflections can be reduced by increasing the

illumination of the area outside the glass enclosure and positioning the cameras closer to

the glass. Reflections can also often be avoided by covering light sources behind or next

to the camera. If these measures do not help, a polarization filter can be fitted in front of

the lens.

– Sharpness:

When checking recordings, care should be taken that persons and objects are sharply

delineated within the defined recording zone. To improve the image sharpness, "gray" or

ND filters can be placed in front of the lens.

– Contamination:

The quality of the recordings is frequently affected by dirt on the lens or the window of

the security housing.

Errors or functional problems can be fixed by

1. disconnecting and reconnecting the local or remote connection in the video system

program

2. exiting the program and booting it again, or

3. warm starting or switching the system off and then on again (with a wait time of

approximately twenty seconds).

If this does not restore normal operation, the configuration must be checked.

If the malfunction cannot be fixed, the system must be replaced.
