156 en | Notes on Service and Maintenance DiBos/DiBos Micro 11.2 11.3 Software Update Installation of the software is carried out principally as Windows® XP Administrator. 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.
