6 Packet Size and Packet Delay
6.1 Packet Size
Packet size can be changed via the GevSCPSPacketSize camera register.
register name : GevSCPSPacketSize
setting value : 512 ~ 9152
*
1 packet contains not only image date, but also a data header with transmission
information. Therefore, by increasing the packet size, the number of packets to
send can be reduced, reducing the overall data volume.
Notes:
Do not set the size larger than your network’s MTU (Maximum Transmission
Unit).
Doing so will result in image data not being able to be sent.
6.2 Packet Delay
Packet Delay can be set via the following register:
・
register name
：
GevSCPD
・
setting value
：
0
～
4294967295
Notes:
Packet Delay is set to 0 at the time of shipping; however it should be set to
as large a value as possible to obtain stable image data.
However, if the value is too large, the frame rate will drop. See 6.3
“Calculating the maximum value of packet delay”to set the most suitable
value.
