Network Related Camera Parameters and Managing Bandwidth AW00097603000302 Basler aviator GigEB.2 Managing Bandwidth When MultipleCameras Share a Single Network PathIf you are using a single camera on a GigE network, the problem of managing bandwidth is simple.The network can easily handle the bandwidth needs of a single camera and no intervention isrequired. A more complicated situation arises if you have multiple cameras connected to a singlenetwork adapter as shown in Figure 68.One way to manage the situation where multiple cameras are sharing a single network path is tomake sure that only one of the cameras is acquiring and transmitting images at any given time. Thedata output from a single camera is well within the bandwidth capacity of the single path and youshould have no problem with bandwidth in this case.If you want to acquire and transmit images from several cameras simultaneously, however, youmust determine the total data output rate for all the cameras that will be operating simultaneouslyand you must make sure that this total does not exceed the bandwidth of the single path (125MByte/s).Because a single aviator GigE camera operating at full resolution and a high framerate uses almost 100% of the bandwidth available on a GigE network path, thissection does not generally apply to aviator cameras. However, if you are operatingaviator cameras with small AOIs and at reduced frame rates, it may be possible tohave multiple cameras on a single path. In that case, the information in this sectionwould be helpful.1 PortGigEAdapterGigECameraGigECameraGigECameraGigECameraGigENetworkSwitchSingle PathFig. 68: Multiple Cameras on a Network
