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 160x 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.
⁃
Direct
The Direct command can move the focus lens to the
specified focus lens position.
⁃
Auto Focus
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
