Hi vinayak

this depends on resolutions@fps and as raw estimation one can consider

100 Mbps/4=25Mbps (~3MB/s) per camera, that results to VGA@10fps

In general this performance corresponds to what is practically

achieved with i.MX27 IP Camera Design

Hello,

Basically I want to get H.264 compressed data from 4 Ip cameras with ethernet cable of 100Mbps "each". Then I want this traffic on single port using switch then as per calculations if  use below specs:

"

HD 1080P/2MP

30 fps

H.264

Expect 4 Mbps per camera

"

That 5th port of 100Mbps would suffice? But Will iMx6 be able to process all 4 videos at same time?

470 Mbps is max. i.MX6 ENET performance (ERR004512)

HD 1080P/2MP 30 fps => 60MP/s, assuming 1 byte/pixel =>

480 Mbps
