Not sure what you mean by "panel" but if you have a desktop hmi....
I have used logmein for remote control from Andriod and Iphone/Ipad with great success. I have a client that uses PCAnywhere, but PCAnywhere only provides a mobile app for Windows systems.
I'm currently trying to get a demo of a Secomea system to test out. Don't know much about it right now, but they do offer mobile apps.
