Panasonic AW-HE130W Operating Instructions Manual page 118

Troubleshooting (continued)
Symptom
The pictures are too light or too dark
Images are in black and white
Auto white balance adjustment
(AWB) is not possible
The screen is too bright in night
mode
The iris does not operate in night
mode.
The subjects appear distorted
When the flash is fired during
shooting, only the top or bottom of
the screen becomes lighter
The brightness changes cyclically
or the colors change, and horizontal
stripes can be seen passing across
the screen
When fine lines or cyclical patterns
are shot, flickering is seen or
coloring is added to them
Noise occurs in the audio input

• 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.
• Is the unit in night mode?
→ I n night mode, output will be in black and white.
• Is the unit in night mode?
→ A uto white balance adjustment (AWB) is not possible in night mode.
• The aperture is set to open in night mode to prevent video voyeurism. Adjust the
brightness at the light source.
• 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.
• 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.
• 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.
• 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.
• The following causes are possible.
- The camera, switching hub, or peripheral devices are not grounded.
- Power lines are running nearby.
- E quipment generating strong electric or magnetic fields (e.g., television and radio
antennas, air conditioning motors, power transformers) are located nearby.
I f 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.
