Rate limit network cameras

Postby ampp » Mon Aug 31, 2009 8:07 pm

I have a 3megapixel ip camera set to grab a image every few seconds. Normally this wouldn't be a problem however i send the images over a wireless link with other traffic also. The camera has a rate limiting feature however due to how bandwidth shaping works and how queues fill up it doesn't respond in enough time. I see a 3mbit burst, and a spike in latency, even when its set to 1mbit.

Wget/curl have methods of only downloading a certain rate which would fix the problem if done on the zone minder box. If this is an easy tweaked id be fine with that but overall it would be a nice feature to enter the maximum rate to download a image at over the net.

wget/Curl into a local FIFO file then have ZM read from the FIFO, you have your rate limiting and minimal work:)
