I look at the 3GS video whenever iCamSource sends me notice of movement on that camera. On bright, clowdy and windy days there is a lot of movement and I get many notices.
So, yes. ICamSource is watching the feed from the 3GS camera all the time. I use iCam, the iPhone's Safari browser, and some other iphone apps (trying many...) to also view the 3GS camera feed.
I'm beginning to think it may be my 3GS iPhone. I borrowed another 3GS that has been running ipCam for several days (since Tuesday AM). The longest sequential run yet. Look at
http://71.240.189.226:12344 It is on the same wifi router.
Unless room lighting is an issue, both 3GS phones are configured the same. I used an iTunes 3GS restore file to make them both the same configuration. Only the local IP address and assigned network port is different. I'll swap 3GS camera locations tonight and see if anything changes over the weekend.
