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.
Image freezes momentarily
The camera has a feature that lets the user momentarily freeze the image.
Double-click (press the puck in quickly two times) the JCU puck to freeze the
image. The snowflake image icon appears on the screen. Any any other action
with the JCU (moving the puck or pushing a button) will unfreeze the image.
By design, the camera image will freeze momentarily on a periodic basis during
the flat field correction (FFC) cycle. A shutter activates inside the camera and
provides a target of uniform temperature, allowing the camera to correct for
ambient temperature changes and provide the best possible image. Just prior to
the FFC, a small green square will appear in the upper left corner of the screen.
Note: Pressing and holding the COLOR button causes the thermal camera to
do an FFC operation.
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.
On Screen Messages
In some circumstances, a status or alert message may appear on the video
screen. This section describes the messages and the appropriate actions that
may be necessary.
