pronounced the losses. Unfortunately this is one of the most common and unnecessary problems
that plagues video systems in general.
Cable characteristics are determined by a number of factors (core material, dielectric material and
shield construction, among others) and must be carefully matched to the specific application.
Moreover, the transmission characteristics of the cable will be influenced by the physical environment
through which the cable is run and the method of installation. Use only high quality cable and ensure
the cable is suitable to the marine environment.
Check cable connector terminations. Inferior quality connections may use multiple adapters which
can cause unacceptable noise. Use a high-quality video distribution amplifier when splitting the signal
to multiple monitors.
Image too dark or too light
By default the FC-Series camera uses an Automatic Gain Control (AGC) setting that has proven to be
superior for most applications, and the camera will respond to varying conditions automatically. The
installer should keep in mind that the sky is quite cold and can strongly affect the overall image. It may
be possible to avoid a problem by slightly moving the camera up or down to include (or exclude) items
with hot or cold temperatures that influence the overall image. For example, a very cold background
(such as the sky) could cause the camera to use a wider temperature range than appropriate.
There are five Scene Presets that use a combination of settings to produce different configurations
that could improve the video image for a given set of conditions. The presets can be toggled with the
Scene Presets button on the Live Video page.

The presets can also be selected from the Scene Presets in the Setup page. Refer to Thermal Image

Eastern or Western Exposure
Once installed, the camera may point directly east or west, and this may cause the sun to be in the
field of view during certain portions of the day. We do not recommend intentionally viewing the sun,
but looking at the sun will not permanently damage the sensor. In fact the thermal imaging camera
often provides a considerable advantage over a conventional camera in this type of back-lit situation.
