Yes but then your stuck with only being able to use avigilon cameras. Milestone is expensive especially when you consider that the likes of Dahua and Hik are free and they are catching up quite quickly with their analytics. The deciding factor between Milestone and cheaper solutions is risk, if anything happened to avigilon you stuck with something you cant expand or repair, the Dahua and Hik are in my opinion high risk if you are going to use them in a MOD site or similar, that only really leaves Milestone unless you have your own solution. I have just quoted Dahua for a 164 camera system, its a low risk site if the Chinese want to log in and watch people driving around a car park thats fine with me, though I will make it quite hard for them to do that in the first place with a VPN
