I just upgraded from UI4 to UI5 the latest version. I went through at least a day trying to get my Foscam to stream video...read dozens of forums threads trying to figure it out. Got it working finally, but was disappointed with the latency/lag of the actual movement and the response time before the video refreshed with the same movement...was around 5 seconds. Also, I was disappointed that I was not able to get the Foscam motion sensor device added unless I upgraded to UI5. So, after some researching and posting the community some questions about UI5 reliability at this point, I upgraded. As soon as I added the Foscm 2.2 plugin, everything on my camera started working with no configuration changes needed. Highly recommend!
