be radiating heat energy that has been absorbed during the day due to solar
loading. Greater temperature differences in the scene generally will allow the
camera to produce high-contrast imagery.
Performance may also be affected when objects in the scene are wet rather than
dry, such as on a foggy day or in the early morning when everything may be
coated with dew. Under these conditions, it may be difficult for the camera to
show the temperature the object itself, rather than of the water coating.
Eastern or Western exposure
While a boat is under way, the camera may inevitably end up pointing 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.
However, the sun may introduce image artifacts that will eventually correct out
and it may take some time for the camera to recover. The amount of time needed
for recovery will depend on how long the camera was exposed to the sun. The
longer the exposure, the longer the recovery time needed.
Multiple Cameras and/or JCUs on a single network
You can configure your system with multiple cameras and multiple JCUs on the
same network. More than one JCU can be used to control a given camera. The
camera will respond to commands from both JCU's in the order the commands
are received across the network. Unpredictable behavior may result from users
sending conflicting commands from separate JCU's (for example, one user pans
left and the other user pans right). In general, the camera will respond to the last
command received and there is no way to set priority, given that IP networks use
a "best effort" delivery protocol.
