(10) Configuring the Target Frame Setting (INDICA-
TOR)
Use this setting to specify whether a target frame
should be displayed around the target during auto
tracking. The target frame can be used to specify the
target being tracked during pan, tilt, and zoom
operations.
1. Move the cursor to INDICATOR, and then tilt the
joystick left or right to select a target frame.
OFF
:
Turns off display of the target
frame.
This is the factory default setting.
CANDIDATE
:
Displays a target assist frame dur-
ing manual tracking. During manu-
al operation,
is shown in the
centre of the screen.
TARGET
:
Displays a target frame during
auto tracking. When movement is
detected,
appears in the four
corners of the screen. When auto
tracking starts, an
frame sur-
rounds the target.
ON
:
Displays a CANDIDATE and TAR-
GET target frame.
Note:
When auto tracking starts while
is
displayed in the centre of the screen, motion in the
centre of the screen is detected.
When auto tracking starts while
is not
displayed in the centre of the screen, the motion in
the entire screen is detected.
Important: About auto tracking
The following types of targets can cause operational
errors or make tracking impossible.
• A target or background with low contrast
• Water or dirt on the dome
• An environment with extreme changes in
illumination
• An environment where there is excessive other,
non-target movement
• Movement along the camera's optical axis (vertical)
• Movement of the target in the vicinity directly below
the camera
• An environment where there is extreme flickering
• Environments where there is light shining onto the
dome from a window, reflected from a road surface,
from back lighting, etc.
• Target becoming hidden by a utility pole or other
object
• Target movement that is very fast or very slow
• An unsteady camera
Important:
In order to improve detection accuracy, it is
recommended that the camera be used in an
environment with the following conditions.
• Target size is approximately one-fifth (vertically) of
the monitor screen.
• TILT angle is within the range of 20° to 55° (page
40).
