Troubleshooting (continued) Symptom Cause and solution The pictures are too light or too dark • Either select the auto setting for the iris or select the manual setting and adjust the iris manually. • The pictures may be dark if the analog video signal cables are too long because this will cause signal attenuation. Images are in black and white • Is the unit in night mode? → In night mode, output will be in black and white. Auto white balance adjustment (AWB) is not possible • Is the unit in night mode? → Auto white balance adjustment (AWB) is not possible in night mode. The screen is too bright in night mode The iris does not operate in night mode. • The aperture is set to open in night mode to prevent video voyeurism. Adjust the brightness at the light source. The subjects appear distorted • Since this camera uses an MOS image device, the shooting timing differs slightly at the top left and bottom right of the screen. This means that if a subject has moved quickly across in front of the camera, it may appear slightly distorted. This is normal and not indicative of any problem. When the flash is fired during shooting, only the top or bottom of the screen becomes lighter • With a MOS image sensor, the shooting timing differs slightly between the top left and bottom right of the screen. This means that when the flash is fired, the bottom of the screen will become lighter in the field concerned and the top will become lighter in the next field. This is normal and not indicative of any problem. The brightness changes cyclically or the colors change, and horizontal stripes can be seen passing across the screen • These phenomena (flicker) may occur under the illumination produced by fluorescent lighting, mercury bulbs or other types of discharge tubes. In such cases, we recommend setting the electronic shutter speed to 1/100 in regions with 50 Hz power supply frequency, and to OFF in regions with 60 Hz power supply frequency. When fine lines or cyclical patterns are shot, flickering is seen or coloring is added to them • This phenomenon occurs because the pixels are arranged systematically on each image sensor. It is noticeable when the spatial frequency of a subject and the pixel pitch are brought into proximity so change the camera angle or take other such action. Noise occurs in the audio input • The following causes are possible. - The camera, switching hub, or peripheral devices are not grounded. - Power lines are running nearby. - Equipment generating strong electric or magnetic fields (e.g., television and radio antennas, air conditioning motors, power transformers) are located nearby. If the problem cannot be resolved via movement of surrounding devices, use a microphone equipped with an amplifier, or connect an audio output with low output impedance.

• Since this camera uses an MOS image device, the shooting timing differs slightly

moved quickly across in front of the camera, it may appear slightly distorted.
This is normal and not indicative of any problem.

• The following causes are possible.
- The camera, switching hub, or peripheral devices are not grounded.
- Power lines are running nearby.
- Equipment generating strong electric or magnetic fields (e.g., television and radio
antennas, air conditioning motors, power transformers) are located nearby.
If the problem cannot be resolved via movement of surrounding devices, use a
microphone equipped with an amplifier, or connect an audio output with low output
