Thermal camera surveillance mode
In surveillance mode the camera pans left and right
continuously.
The camera continues to pan until surveillance mode
is disabled, or the camera controls are used to move
the camera. When this occurs the camera does not
automatically resume surveillance mode and the
mode must be enabled again if required.

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
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
