PTZ cameras — Erratic or unresponsive controls
Possible causes Possible solutions
Network problem. • Check that the controller and camera are
correctly connected to the network.
• If used, check the status of the network switch.
• Check that RayNet cables are free from damage.
Control conflict, e.g.
caused by multiple
users at different
stations. Ensure that no other controllers are in use at the
same time.
Problem with the
controller. • Check power / network cabling to the controller
and PoE injector, if used.
• Check other controllers, if available.
Cannot switch between camera feeds
Possible causes Possible solutions
Camera is not a dual
payload model.
Only “dual payload” (dual lens) cameras support
feed switching.
Noisy image
Possible causes Possible solutions
Poor quality or faulty
cabling. • Ensure cable runs are no longer than they need
to be.
• Use only high quality shielded cable suitable for
the marine environment.
Cable is picking
up electromagnetic
interference (EMI)
from another device. • Ensure you are using a high quality shielded
cable.
• Ensure proper cable separation, for example do
not run data and power cables in close proximity
with each other.
• In certain conditions it may be necessary to
fit suppression ferrites to cabling to eliminate
interference.
Image too dark or too light
Possible causes Possible solutions
Brightness set too
low. Check MFD brightness and adjust if necessary.
The contrast and / or
brightness settings in
the Camera app are
set too low. Check Camera brightness and contrast, adjust if
necessary.
The Scene Mode
is not appropriate
for the current
conditions. When viewing a thermal camera feed, a particular
environment may benefit from using a different
Scene Mode setting. For example, a very cold
background (such as the sky) could cause the
camera to use a wider temperature range than
appropriate. Adjust the Scene as appropriate.
Image freezes momentarily
Possible causes Possible solutions
FFC (Flat Field
Correction). A Thermal camera’s image will pause momentarily
on a periodic basis during the Flat Field Correction
(FFC) cycle. Just prior to the FFC, a small green
square may appear in the upper left corner of the
screen.
Image is inverted (upside down or mirror image)
Possible causes Possible solutions
Vertical or Horizontal
flip control incorrectly
set Check the image flip controls to ensure they are
set correctly for your installation.
