This article gives you guidelines on how to proceed in problem-solving regarding the GigE cameras in DewesoftX.
Using two or more network cards doesn't recognize multiple cameras, only partially
Check if network cards have equal subnet mask. You should configure them in a way that each network card has its own subnet.
This is the right configuration of network cards. If more than two network cards are used please follow analogy below.
While you're configuring a network card check that only one subnet is used in Advanced settings. If there are more remove the rest of them.
For Advanced TCP/IP Settings follow the path: Ethernet Properties/Properties/Advanced
REG_EXPAND_SZ error when installing the OptoMotive OptoStream SDK
Filter driver is not installed
Check that you don't have DewesoftX and OptoStream Viewer opened at once. Both programs are managed to use the same driver which means one occupies it and disables access to the other application.
DS-CAM-600 camera is not recognized in DewesoftX as well as isn't in OptoStream Viewer
DS-CAM-600 camera has an LED light integrated which indicates the operation mode of the camera. Three different colors indicate different problems. Red or orange means that there is a problem with a configuration. You should power-cycle the camera and wait that it's booted again. Green light means that everything works fine. Please note that the camera needs a few minutes before the light switch to the green since there is an operating system on the camera that needs to be booted.
