If they just had a free 4-8 camera version to test things out, and maybe run a Axxon server beside your normal customer setup.. I think their user interface seems clumsy and ugly, and i need more than 30 days to get use of it. It is simply not love at first side, I think i have to sleep next to it minimum half a year just to get my eyes to accept it. When you have been using Milestone in almost 10 years it is hard to adapt to other interfaces..
We have also been using Axxon for several years now. We ave multiple systems deployed and we are using LPR, Facial Recognition and human perimeter detection. Our clients use the system daily and we have not had any complaints about the UI.
