I like how easy it was to set up, with some help from my tech support team! It's very customizable for our needs/requirements (aside from being able to see who has entered). We haven't found any way in which we dislike this software - but if you have questions about what features could be added please let us know because there are many things missing compared other vendor products out there today as far as access control goes!! The best thing? Customer service. They're always available when needed via email / phone calls etc., they respond quickly & often solve problems before even asking them ;) Nothing so much yet :) Easy install of hardware devices such as door readers into existing doors without having to replace current locksets by using their RFID card reader device instead.
