Configuring Other Ethernet Settings; Stream Channel Destination Address - FLIR Oryx Installation Manual

use some bandwidth. Therefore, when calculating your bandwidth requirements, you should not attempt to use
the full maximum of 1.25 GB. The default bandwidth is 850 MB.
To calculate your bandwidth requirements:
Determine your required resolution, frame rate, and pixel format (bytes per pixel)
For example, for an image that is 4K resolution, 60 FPS, Mono8:
Once you have calculated your required bandwidth, you can allocate an amount to each camera by adjusting the
packet size and packet delay. Allocating a specific amount to each camera helps to avoid dropped packets due to
a data burst. You would do this in a set up with multiple cameras, or in a situation where the system bandwidth
might be limited or shared due to hardware architecture.
Bandwidth Requirements for Multiple Cameras
Multiple cameras can be set up in two ways: 1) Each camera is connected directly to a single Ethernet port; or, 2)
multiple cameras are connected to a single port through an Ethernet switch.
If using the first method, each camera has the full bandwidth allocation available to it. If using the second method,
the combination of all cameras on a switch cannot exceed the available bandwidth.

Stream Channel Destination Address

The stream channel destination address (SCDA) register is used to specify the streaming destination IP address.
The default SCDA is the IP address of the network or computer to which the camera is connected. It can be set
within a range so that the camera sends data as a multicast. As long as switches in the path between the sender
and receivers support and are configured for multicasting, multiple receivers can listen to the data stream from the
camera.
Multicast addresses are between 224.0.0.0 and 239.255.255.255.

Note: If the packet size and packet delay combination exceeds
the available bandwidth, frames will be dropped.
(Height x Width x Frame Rate x Bytes per Pixel)/1000000 = Bandwidth in MB
3840 (H) x 2160 (W) x 60 (FPS) x 1 (BPP) = ~497 MB
