o 3D Noise Reduction—Provides superior noise reduction and is recommended for use in extra low-
light conditions. It is especially useful for reducing blur with moving objects. 3D noise reduction
reduces image noise/snow in low-light conditions by comparing adjacent frames. A higher level of 3D
noise reduction generates relatively enhanced noise reduction, although it creates more motion blur
than 2D noise reduction on moving objects. Four settings are available: Off, Low, Mid, High.
o 2D Noise Reduction—Analyzes individual frames pixel by pixel and frame by frame to eliminate
environmental noise and deliver optimized image quality, especially in low-light conditions. 2D noise
reduction tends to produce superior results for moving objects when applied to areas in the field of
view where movement is present. However, it is less precise than 3D noise reduction. It can be set
On or Off.
· Video Format—When mounted indoors, the visible camera shutter speed can
be synchronized to the 50 Hz or 60 Hz power used for lighting the scene. If
lighting is connected to 50 Hz power, the PAL setting might provide better video
and NTSC might provide better video under 60 Hz lighting.
Where relevant, changing the settings immediately affects the live visible video images and streams. To
save any changes, click Save. To discard changes or return to the factory defaults, click Reset.
3.2.3 Thermal Image Setup - Thermal Page
In most installations, it is not necessary to change the default settings of the thermal sensor. However, in
some situations, depending on weather, time of day, or scene, modifying one or more parameters can
improve the video stream image. Be aware that, when the conditions change, the parameters might need
to be adjusted again. It is also a good idea to know how to restore the factory default settings (see
Firmware & Info Page).
