Actually - I completely forgot that Paxton also has a door handle version called Net2Air - from my previous pricing exercises, this seems to be very competitive as well.
I love it when these things can be integrated together but psydii is right - it doesn't happen overnight.
The trick is to look far enough into the future to ensure all technology that could go together, can come together seamlessly. But I agree it's difficult to do when things are so far away on the horizon but I guess that's where working with a good provider who has seen many of these system can help and offer guidance on things most of us have not thought about.
Paxtons interface is nice and clean and quick to load.
