SENSE UP

 

This function is used to increase the sensitivity by extending the exposure time.

OFF

 

 

 

When the object is dark, this function sets how high the level of sensitivity will

 

 

 

 

automatically increase to. “x32” means that the sensitivity will be increased con-

 

 

 

 

tinuously up to 32 times the normal level.

 

 

 

 

Increasing this value slows the shutter speed and motion may appear unnatural.

 

 

 

 

When the item “SHUTTER” is set to “1/250” or more, the SENSE UP item does not

 

 

 

 

work and “---“ is displayed as the item name in the CAMERA ALC Screen.

As the setting of the “SENSE UP” function is increased, the picture may become rough

 

 

 

 

 

 

 

 

 

 

and whitish, and subject to white blemishes. This is not a malfunction.

 

 

 

 

 

 

 

 

 

When the setting of the “SENSE UP” function is not OFF, flicker may appear on the

 

 

 

 

 

 

 

 

 

 

screen under fluorescent light or mercury lamps. This is due to the principles of the

 

 

 

 

 

 

 

 

 

 

SENSE UP, and is not a malfunction.

 

 

 

 

 

 

 

 

 

There may be cases where flicker can not be reduced even under the following condi-

 

 

 

 

 

 

 

 

 

 

tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current

 

 

 

 

 

 

 

 

 

 

frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial

 

 

 

 

 

 

 

 

 

 

electric current frequency is 60 Hz.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

PRIORITY

 

When an object is dark, this functions sets whether priority during monitoring is

MOTION

*TK-C676 only

 

placed on maintaining the motion of the camera or on picture quality.

 

 

 

 

MOTION : Motion of the camera is given priority. When an object is dark, the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

AGC function is prioritized. This setting is suitable when objects are

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

characterized by quick motion.

 

 

 

 

PICTURE : Picture quality is given priority. When an object is dark, the SENSE UP

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

function is prioritized. This setting is suitable when picture quality is

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

important.

When the “AGC MODE” and “SENSE UP” functions are both set to “OFF”, this function

 

 

 

 

 

 

 

 

 

 

does not work and “---” is displayed as the item name in the CAMERA ALC Screen.

 

 

 

 

 

 

 

 

 

When item “B&W” is set to AUTO, item “PRIORITY” is set to the MOTION priority mode

 

 

 

 

 

 

 

 

 

 

and “---” is displayed.

MEMO

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

As the camera is sensitive to both visible and near-IR light in the B&W mode, there may be

 

 

 

 

 

 

cases in which switching the color mode to the B&W mode causes the image to become out

 

 

 

 

 

 

of focus in certain light source conditions. In this case, if the item “AF FOR IR” (P. 23)

 

 

 

 

 

 

under CAMERA FUNCTION2 Screen is set to “ON”, focus can be adjusted automatically..

 

 

 

 

 

 

Also, use an IR illumination as needed.

The B&W mode is set to ON when the contact is shorted (makes

MEMO

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To ensure switching between the color and B&W modes:

 

 

 

 

 

 

 

 

 

 

Setting item “B&W” to AUTO allows the color and B&W modes to be switched according

 

 

 

 

 

 

 

 

 

 

to the brightness of the object. However, this switching may sometimes not occur de-

 

 

 

 

 

 

 

 

 

 

pending on the lighting condition and viewing angle.

 

 

 

 

 

 

 

 

 

 

To ensure the switching, it is recommended to connect the signal from an external sen-

 

 

 

 

 

 

 

 

 

 

sor (to be purchased separately by the user) to one of the ALARM input terminals of the

 

 

 

 

 

 

 

 

 

 

camera and perform switching according to the sensor signal.

 

 

 

 

 

 

In order to prevent hunting do not set the item “B&W” to AUTO when using an infrared lamp.

 

 

 

 

 

 

 

LEVEL

 

When the “B&W” function is set to “AUTO”, this function sets the signal level of the
