Optical Zoom Limit Settings
The optical zoom magnification can be limited using 

the Optical Zoom Tele Limiter command. The digital 

zoom cannot be used if the limit is set to the Tele side.

Digital Zoom
A maximum of 16x digital zoom can be set with the 

Digital Zoom Tele Limiter command. Together with 

the optical zoom, a maximum of 480x is possible, 

however, the resolution decreases.

Although the vertical resolution can be increased by 

enabling the V-Reso.UP function using the V-Reso.

UP ON command, residual images and blurring may 

become more apparent with moving subjects.

Manual Focus
The manual focus can be operated using Far/Near or 

directly moving the focus to a specific position.

⁃

Transmit the Far or Near command to execute the 

Far/Near operation at the speed configured by the 

Far/Near Speed command. The Stop command 

stops the operation. (The operation does not stop 

without transmitting the Stop command.)

The speed targets are as follows.

⁃

The Direct command can move the zoom lens to the 

specified focus lens position.

⁃

The Auto Focus ON command sets the mode to auto 

focus and automatically focuses on the subject if 

the subject moves. This mode is cancelled when the 

Manual Focus ON, Near, or Far command is used.

Although the minimum focus distance is set to 1m by 

default, this can be changed by using the Near Limiter 

command. In addition, the sensitivity of the AF to the 

change in subject can be changed using the Auto 

Focus Sensitivity command and the focusing area can 

be changed using the Focus Area command.

One-Push Auto Focus
The auto focus can be moved only once using the 

One Push Trigger command. The mode prior to 

starting the auto focus is retained after focusing.

Focus Lens Offset
When covering a camera, such as the dome camera 

with a cover or similar, the refraction of the light due to 

the cover changes the OPL. This may result in close 

subjects being out of focus when using a powerful 

zoom.   

In that case, it is necessary to move the range of 

motion of the focus lens depending on the change in 

OPL.

Validate the Offset using the Cover Offset ON 

command and transmit a Cover Offset Level 

command so that subjects that are at approximately 

1m TELE edge (When the Near Limit is 1m) are in 

focus. 

In the same way that 0 sets the level to OFF, the 

larger the number, the greater the offset. 

⁃

Auto Trace White Balance.

・

SMART ATW

　

This mode controls retracing of ATW according

　

 to the size of single-colour object in the screen, 

　

addition to normal ATW mode control.

　

In case the single-colour object covers most of 

　

the area in the screen, WB control function shall 

　

be stopped.

　

Also, the retracing speed is slower than that of 

　

normal ATW mode.

　　

*This mode is valid when WB mode is set to ATW.

⁃

The Push-Lock Auto White Balance starts retracting 

using the One Push Trigger command and locks the 

white balance after approximately 2 seconds.

In addition, after executing the One Push Trigger 

command, the mode returns to the previous mode 

by executing the AWC Reset command.

Color temperature 3200K fixed mode.

⁃

Color temperature 5600K fixed mode.

Manual White Balance. The R and B gains can each 

be configured to a range of 0 to 255.
