Interresting results. When I analyzed approx 100 invoices for projects in North America where there was access control + video, on average 10 doors and 6-8 cameras, I found the split to be as follows:

20% Access Control Hardware and Licenses

10% Video Hardware (cameras only)

13% Miscelaneous (contacts, strickes, closers, mounts etc)

57% Installation/project management

Even if the project was larger the percentages would stay in the same range. Now this was back in 2007 so maybe I need to do another audit to see if these percentages have changed since technology has improved and product costs have come down.
