Although I've moved on, I am still in touch with my colleagues working at a large airport using Genetec. They've recently upgrade of Genetec to 5.9 to allow the addition of AOM. Hasn't been completly rolled out, they've had to apply some hotfixes in the first month. That being said, Genetec (Omnicast) had growing pains when first deployed at the airport. Yes it is expensive. I'll have to keep in touch and provide updates.
