Not Razberi, but, I have playing with the Lenovo PX-2 with Arcus. I used a Computar Ganz NMD-2003 camera (onvif compliant to Arcus), an Axis M 1014 and an Axis 5014 PTZ (native compliant to Arcus). Everything was hooked up through an Adtran 24 port POE switch. I wanted to see how "plug and play" it was. I opened the Milestone software via webbrowser through my laptop connected to the switch and the three cameras popped up before the page fully loaded! The Axis cameras were labeled Axis and the Ganz camera had the IP address labeled. Pretty easy for initial set up. I then accessed the cameras to set a few features (fps, H264, days recording, etc) and saw that the motion detection even has some basic masking set up in it. I set up some recording and reviewed the play back. Again I was impressed with the easy setup and not having to refer to a manual. I was able to use the PTZ on the 5014 via my mouse and it responded well. I also accessed the software from my browser on my Ipad over my WLAN and had good picture quality and good response. It does not have all the features of the other Milestone VMS but for a quick easy set up I thought it was pretty good.
Hope this helps..
