What is the "Add Remote GigE Camera" feature in pylon for?
If you want to access a GigE camera with a known IP address that was configured in a different subnet and was connected to a router, you will fail, because such cameras are "hidden" for pylon and its Broadcast UDP Device Discovery Messages due to the routers "swallowing" all broadcast messages.
Hence, one cannot normally discover a GigE camera being connected to a router.
For that purpose the "Add Remote GigE Camera" feature (push F9 in pylon viewer) was implemented in order for users to be able to discover a GigE camera configured in a different subnet and connected to a router if they knew its IP address in advance. In this case, pylon will send a Unicast UDP discovery message and hence discover the camera and enable you to configure it and grab images.
In order to test this feature (if you did not have a router at hand) you may take 2 PCs and a switch and configure them the following way:
- pylon application runs on PC1
- IP address of network adapter is 192.168.0.2 (255.255.255.0)
- gateway for that adapter is configured as 192.168.0.1
- network adapter is connected to a switch
- Windows XP, configured as router (i.e. IP forwarding is enabled: Microsoft TechNet )
- adapter 1: 192.168.0.1, connected to the same switch as PC1
- adapter 2: 192.168.1.1
- camera: 192.168.1.100, camera is connected to adapter 2
