IP cams, like Airlink 747W, can be controlled through the web interface remotely if you have the port forwarded. I have my 747W on Icamsource, but can also see it and control it on the internet and on SkyIPCam app on my phone. Also need a host domain in case the your IP is not static and run dns updater or add the host domain info in the router. I finally got all of this working at a remote site after reading older posts here and getting advice from the fine people at SKJM.
It would be nice to control pan and tilt through Icamsource, but it can be done in other ways. I'm sticking with Airlink IP cams, I like the SkyIPCam app and the web interface.
