INT/LL switch

INT (internal) control switch

When the internal synchronization is used, set the switch to the INT side.

LL (Line-Lock) control switch

Matching the vertical synchronization with the power frequency is called the line-lock.
When two or more cameras are switched by the video switcher to a monitor TV, the vertical
sync. phase can be locked with the power frequency, and a stable vertical sync. is obtained
without being disturbed at the time of switching.
Line-lock is operative only when the AC 24V power supply is connected.

Caution:

1.The camera is synchronized to the power frequency of 60Hz 0.5Hz covering a
normal fluctuation of the power frequency. The camera may not compensate for
large fluctuation caused by power generated by an engine generator. etc.

2.It takes about 10 seconds or more to obtain a stable synchronization after the
power is turned on. This is necessary to stabilize the camera against the power
noise.

BLC (Back Light Control) switch

In case the back lighting is too bright to shoot the main object clearly, set this switch to ON
position.

- 5 -

SENS-UP switch

To increase the sensitivity, set this switch to ON position.

DAY/NIGHT switch

When the DAY/NIGHT function is used, this switch is turned ON. (See P. 9.)

Camera output terminal

This is an image output terminal. When the camera direction, the field angle or the focal point is
adjusted, a monitor TV or other type display is connected to this terminal.
When a monitor TV is connected to this terminal, remove the 2P connector beforehand.

Level adjusting volume

This volume is used to adjust the brightness of the image. If the lens iris is not appropriate,
adjust the iris with this level adjusting volume.

Vertical sync. phase adjustment potentiometer

Vertical sync. phase adjusting potentiometer is set at the position fully that the delay time of
vertical sync. phase against the phase of power frequency is shortest, when shipped from the
factory.

Select this up ( ) and down ( ) button will make the delay time of vertical sync. phase
against the phase of power frequency longer.
Use the function control potentiometer if the picture image on a monitor TV may flow
when using the camera in combination with other camera(s) controlled by the Line-Lock

synchronization.
In this case, get a proper image by shifting the phase of vertical sync. signal of the camera
against that of the other. If a proper image cannot be obtained even after this adjustment, reset

the potentiometer to its original position, and use the function control potentiometer of the
other camera to shift the phase of vertical sync. signal of other camera.

Caution:

Before making adjustment, make sure that cameras have their power supplies
connected with the same polarity. (not 180 apart)

This camera is provided with Day/Night function that can detect the brightness of the objects and
automatically switch the color mode / black-and-white mode according to the detected brightness.
This function allows the output of ordinary colored images for the outdoor monitoring during
daylight and the output of black-and-white images for the night monitoring with a lack of sufficient
light volume. Therefore, even at night, this camera can provide monitoring through images with
little noise.
Furthermore, since this function raises the sensitivity in the infrared area, even a dark object can be
imaged more clearly at night when a commercially available infrared lamp is used together. To
make this function enabled, set the Day/Night switch on the rear panel to "ON."
When the Day/Night switch is set to "OFF," the camera operates as an ordinary color camera even
at night.
When the Day/Night switch is set to "ON" and the object becomes gradually brighter as the time
passes like dawn, it may take time to switch from the black-and-white mode to the color mode. As a
result, the image taken in the early morning may be in black and white. However, note that this is
not a malfunction.
The Day/Night function controls the mode switching between the color mode and the black-and­white mode according to the signal level.
Since the signal level varies depending on the camera settings to shoot the object, the timing of
Day/Night switching varies accordingly.
When more than one screen is displayed by the controller or the like, the Day/Night mode may vary
depending on the camera shooting conditions even if the brightness is the same.
