Hi John,
We distribute Integrated Control Technology (or ICT), based in New Zealand. NZ (like Australia and Canada) are on cutting edge of large scale unified "access control/alarm/fire reporting" systems (as large scale in the access control department as Lenel or Software House or other enterprise-class offerings).
We don't typically see "enterprise scale" offerings like these from the American manufacturers who make unified systems (DSC, Honeywell, DMP, Bosch, etc...).The American products tend to be traditional alarm panels to which thay have added some access control functionality (typically 32 doors, all decisions made by the alarm "central panel", access modules that have no on-board intelligence or decision-making abilities, less than 200 inputs, 8 alarm areas, a few hundred (up to a thousand) cards, limited third-party integrations, basic management software). I believe that these are the products that both you and Brian are referring to.
ICT's Protégé GX is a unified access control/alarm/fire reporting system but on a much larger scale than what you describe. A single ICT main controller can do 128 doors (using intelligent or non-intelligent door expanders), over 1000 inputs, unlimited alarm areas, 5 million cards, wireless door lock integrations with Salto or Assa Abloy Aperio, 15 different VMS integrations, elevator control (high level or relays), IP and dialer reporting on-board, UL approvals, etc...).
This type of system is price-competitive on the smaller systems (due to the fact that a single panel replaces 3 different sub-systems) but has the feature set to compete on the larger projects. I mentioned ICT but there are many other similar systems coming out of NZ and Australia. Those countries never really used "access control only" systems- since the late 80's they have been selling and installing integrated systems in this region (ICT, Inner Range, Cardax, Tecom (now GE), Paradox).
