MEMO

 

 

 

TK-C625U:

 

 

 

 

 

 

 

 

 

 

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

 

 

 

1/60

 

 

 

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.

 

 

 

 

 

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

 

 

 

 

dBB, and set values cannot be changed.

 

 

 

 

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

 

 

 

 

 

B&W/COLOUR

 

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

 

MODE..(TK-C625E)

 

MEMO

 

 

 

 

B&W/COLOR

 

 

 

 

 

MODE..(TK-C625U)

 

 

 

 

● 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.

TK-C625E:

 

 

 

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

COLOUR

 

 

 

 

 

mode turns OFF when the input contact is open (break).

TK-C625U:

 

 

 

 

 

 

 

 

 

 

MEMO

 

 

 

COLOR

 

 

 

 

 

 

 

 

 

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.

NORMAL

 

 

 

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.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

 

NORMAL

 

 

 

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.
