comes up when right- clicking on an entry in the discovery dialog.
Close the camera view and select the camera again in the
Discovery dialog. Shutdown and restart the PC and select the
camera again after discovery. Check firewall settings (e.g. disable
firewall temporarily and select the camera again after discovery).
Check if the processor speed of the PC is sufficient for displaying
images at the chosen frame rate. If available, connect the camera
to a different network card.
Problem:
No communication is possible between the camera and the
PC
Solution:
Check if a firewall is active. This can prevent to establish any
communication because this is a network issue check firewall
setting. Try to disable temporary the firewall and try again.
Problem:
The video stream stops when adjusting the camera settings
Solution:
This situation happens when the product between frame rate and
exposure time becomes 1 second or greater. Any of the settings
can be reduced in order to get the camera operational again. The
exposure settings field will become red in order to signal that one
of the frame rate or exposure setting has to be reduced.
Problem:
Camera does not respond to light
Solution:
Please execute following steps:
Check if camera is in a “Free Running”-mode. When done, check
with “SVCapture” program if you can read back any data from the
camera like: Type of CCD, S/N number exposure time settings and
so on. If you trigger the camera by hardware: Check if the Exsync
signal is present. The signal swing for must be minimum 5V (max.
24V) Source must provide 10 mA. Below such level the drivers in
the camera will not work. Check also the quality and swing. If
these signals are not there or do not have the right quality (like
spikes) the camera can not read out any frame or delivers
distorted images.
