I have a pair of IPC-HDW4431C-A bought directly from China in 2016 with english firmware. They have different lenses and their firmware might be slightly different. The one in question has firmware 2.420.0000.17.R, build : 2016-03-13. I've configured my router to allow the cameras to connect to a small set of external IP's and block all others. I haven't looked at the routers logs for a while, but I recently did and notice that this one camera is trying constantly to make a UDP connection to 126.96.36.199 on port 8800. That IP belongs to Aliyun Computing (China's version of Amazon AWS I think). I've configured the camera's DNS servers to point to a null local LAN address and have turned off or disabled every type of access protocol I can see in the camera's setup. Any idea what's going on here? I'd like to make it stop so that it doesn't flood my syslog server with useless junk.
