Surveillance mode settings
The scan width and scan speed can be adjusted.
Scan Width
The scan width determines the distance that the camera pans
left and right when in surveillance mode.
Scan Speed
The scan speed determines the speed at which the camera pans
left and right when in surveillance mode.
Setting scan width
The surveillance mode scan width can be adjusted by following
the steps below.
From the thermal camera application:
1. Select Menu.
2. Select Camera Set-up.
3. Select Surveillance Settings.
4. Select Scan Width.
The scan width options will be displayed:
• Narrow — The camera will scan approximately 20º left
and right of the center (40º total).
• Medium — The camera will scan approximately 40º left
and right of the center (80º total).
• Wide — The camera will scan approximately 80º left and
right of the center (160º total).
5. Select the required option.
Setting scan speed
The surveillance mode scan speed can be adjusted by following
the steps below.
From the thermal camera application:
1. Select Menu.
2. Select Camera Set-up.
3. Select Surveillance Settings.

Thermal camera stabilization
The Raymarine T470SC and T473SC thermal cameras includes
a mechanical stabilization feature.
The mechanical stabilization feature improves image stability
by compensating for vessel motion and keeping the camera
aimed at the point of interest. Mechanical stabilization has
two aspects: horizontal (azimuth) and vertical (elevation). By
default, mechanical stabilization is set to on, which provides the
best on-the-water performance particularly when the vessel is
underway and traveling on rough water or in swell conditions.
You can disable or enable stabilization whenever you want.
When you enable full stabilization (horizontal and vertical), the
Stabilization On (no wave) icon flashes. It does not display
continually, since this is the normal mode of operation. If you
disable stabilization, the Stabilization Off (wave) icon remains
on the screen to make you aware that the motion of the vessel
can affect the camera performance. This is not a normal mode
of operation. Stabilization is automatically turned off when the
camera is stowed, but the system restores your setting when the
camera is powered on. You can turn off the horizontal (pan)
stabilization while retaining the tilt stabilization by enabling point
mode.
Enabling / Disabling stabilization
Stabilization is enabled by default. You can enable or disable
stabilization at any time by following the steps below.
From the thermal camera application
Thermal camera application — Pan and tilt cameras
1. Select Menu.
2. Select Camera Set-up.
3. Select Stabilization Mode.
Selecting Stabilization mode switches stabilization On and
Off.
Thermal camera point mode
Point mode is only applicable to thermal cameras which have
mechanical stabilization.
Enabling point mode only has significance when stabilization
is enabled. Enabling point mode turns off the horizontal (pan)
stabilization while retaining the vertical (tilt) stabilization. This
can be helpful when you want to use the thermal camera as an
aide to navigation and keep the camera pointing in the same
position relative to the vessel as it turns. For example, you may
have stabilization enabled and have set the camera to point
straight ahead relative to the front of the vessel. If the vessel
is turned at a sharp angle under these conditions, the camera
sensor will not follow the direction of the vessel. Enabling point
mode keeps the camera in sync with the vessel direction while
maintaining a stable elevation position. When point mode is
enabled, a lock icon displays. The camera's azimuth position
is now locked to the base. When you disable point mode, the
unlock icon displays momentarily. The camera always starts
up with point mode disabled.
Enabling / Disabling point mode
Point mode is disabled by default. With Stabilization enabled
you can also enable point mode at any time by following the
steps below.
From the thermal camera application:
1. Select Menu.
2. Select Camera Set-up.
3. Select Point Mode.
Selecting point mode switches point mode On and Off.
