Function/Set Value

Initial
Value

SHUTTER

Sets the speed of the electronic shutter.

Set Values
TK-C625E : 1/50, 1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000
TK-C625U : 1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000

MEMO

● To reduce flickering that occurs under fluorescent lighting, set the shutter speed to 1/100 if your local

power supply frequency is 50 Hz (TK-C625U), and to 1/120 if it is 60 Hz (TK-C625E).

● The higher the shutter speed, the more prominent will be the smear phenomenon. This is a

phenomenon that is characteristic of CCD, whereby white stripes appear at the top and bottom of a
bright light source.

TK-C625E:
1/50

TK-C625U:
1/60

AGC MODE

Sets the maximum gain of the AGC (Auto Gain Control), which electronically increases the
gain when the object is under low light conditions.
OFF

: Disable AGC.

10 dB : Increase gain by a maximum of 10 dB according to the brightness of the object.
20 dB : Increase gain by a maximum of 20 dB according to the brightness of the object.

MEMO

● When the AB&W MODEB item is set to AAUTOB, the AAGC MODEB item will be automatically set to A20

dB

B, and set values cannot be changed.

● The screen may appear grainy at dark places when the gain level is increased.

10 dB

B&W/COLOUR
MODE..(TK
-C625E)
B&W/COLOR
MODE..(TK
-C625U)

For performing setting related to switching between the B&W and Color modes.

MEMO

● When in the B&W mode, this camera is sensitive to both visible and near-IR lights. As such, images

may become out of focus upon switching from the Color to B&W mode, depending on the type of light
source used. In this case, re-adjust the focus in the B&W mode. In addition, when the

AAF FOR IRB

(A pg. 25) item is set to

AONB, focus can be adjusted automatically during mode switching.

● Make use of an IR light as and when necessary.

^

B&W MODE

For setting the function on switching from Color to B&W mode.
COLOUR : Color mode at all times and will not switch to the B&W mode. [For TK-C625U,

this is displayed as

ACOLORB.]

B&W

: B&W mode at all times.

AUTO

: Switches automatically to the Color mode when brightness level of the object is

high, and to the B&W mode when brightness level of the object is low.

ALARM IN

: Switches to the B&W mode when there is an alarm input.B&W mode turns ON

when input contact of the camera's input alarm is short (make), and B&W
mode turns OFF when the input contact is open (break).

MEMO

To ensure proper switching between B&W/Color mode
● Switching between the B&W/Color mode can be performed automatically according to the brightness

of the object by setting the

AB&W MODEB item to AAUTOB. However, switching may fail depending on

the lighting conditions and angle of view. In order to ensure proper switching, it is recommended that
switching be performed by inputting signals from an external sensor (sold separately) to the alarm
terminal of this camera.

LEVEL

For setting the signal level of the object at which switching to the B&W mode is to be
activated when the

AB&W MODEB (A pg. 27) item is set to AAUTOB.

LOW

: Switch to the B&W mode when signal level of the object is low.

NORMAL : Switch to the B&W mode when signal level of the object is normal.
HIGH

: Switch to the B&W mode when signal level of the object is high.

MEMO

● When the AB&W MODEB item is set to a value other than AAUTOB, "- - -" will be displayed and setting of

the LEVEL item will not be possible.

NORMAL

LIGHT TYPE

For setting the type of lighting used for the object when in the B&W mode.
NORMAL : Set to this when a normal light is used.
IR

: Set to this when using an infrared emission light.

MEMO

● Switching from the Color to B&W mode may not function correctly if the AIRB setting is used under

ordinary sunlight or fluorescent light.
