Setup NIC 2 for Camera 2 a. Set NIC address to 192.168.20.2 (255.255.255.0). b. The camera will automatically be given the address 192.168.20.3 (255.255.255.0) when AutoVISION/Visionscape starts. 2) Setting Jumbo Packets (Jumbo Frames) For best performance, the NIC should be set up to use Jumbo Packets (sometimes called Jumbo a. Click on each NIC in turn b. Click on Properties c. Click on Configure button next to the network card description d. Click on Advanced. Using Sentech STC-M Cameras with AutoVISION and Visionscape Page 9 of 35 The GigE camera image is transferred to the PC in a series of UDP Packets. Each time the PC receives an Ethernet packet, a PC interrupt takes place.
Each interrupt disturbs the image transfer flow and causes CPU loading and possible packet drops due to several OS internal switchover processes. The smaller the packet size, the more interrupts that will occur. The larger the packet size, the more efficient the image transfer will be. Frames) which are 9014 bytes in size. This will increase the network performance, decrease the PC’s CPU load, and minimize packet drops.
