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

Cause and remedial action
● These phenomena (flicker) may occur under the illumination
produced by fluorescent lighting, mercury bulbs or other types of
discharge tubes.
In cases like this, it is recommended that the electronic shutter
speed be set as follows.
When the Frequency is set to "59.94Hz"
● Set to 1/100 in areas where the power line frequency is 50 Hz.
● Set the electronic shutter to OFF in areas where the power line
frequency is 60 Hz.
When the Frequency is set to "50Hz"
● Set to 1/120 in areas where the power line frequency is 60 Hz.
● Set the electronic shutter to OFF in areas where the power line
frequency is 50 Hz.
● This can also be resolved by setting the shutter mode to
[Synchro] and adjusting the shutter value.
● 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.
● When the high dynamic range function (HDR) is enabled,
flickering may be noticeable depending on the subject. This is not
a malfunction. If necessary, disable the HDR function.
● Are the camera, switching hub, or other peripheral devices
grounded?
● Are power lines are running nearby?
● Is equipment generating strong electric or magnetic fields (e.g.,
television and radio antennas, air conditioning compressors,
power transformers) located nearby?
If the noise is not reduced via movement of surrounding devices,
use a microphone equipped with an amplifier, or connect an audio
output with low output impedance.
● Has "Disable" been selected for "Tally"?
When "Disable" is selected for "Tally", the camera's tally lamp will be
off. Change the setting to "Enable".
● Has "Off" been selected for "Record tally"?
When "Off" is selected for "Record tally", the unit's tally lamp does
not light during recording to an SD card. Change the "Record tally"
setting to "On".
