I recommend that you ask your self what features does this customer really need, or will actually use in the long run. Never short change the customer on image quality so always choose HIKVISION, particularly the DARKFIGHTER series. But regarding the 'VMS', do you need a system that is easy to navigate? Easy to playback stored video? and does not break the bank whatsoever with "unneeded" licensing fees choose iVMS-4200. It is not a 'heavy' software loaded with features that look really cool but are completely useless to the client. Option 2 Show the client both, explain why Avigilon costs more, Explain Cyber security and why the network should be isolated. Price the HIKVISION slightly under the Avigilon to maximize the margin, and close the sale, always.
