An integrator I know is hooked up with a developer, wiring two or three brand new neighborhoods a year. Enough people opt for equipment, and enough of those people sign up for alarm monitoring, to make it worth it, although the home buyers can always hire someone else to install the equipment, or decide not to have the equipment installed at all. And he's getting paid by the developer for the fire alarm in any case, so he's profitable from day one even if the home buyer never gets a single add-on.
They wire for full intrusion (all doors, all accessible windows, several motion detectors), commercial fire including sprinkler activation and notification (they have had several customers with hearing impaired and developmentally disabled family members opt for strobes in addition to sirens), intercom, with doorphone, door strike release, wiring for master units in the kitchen, master bedroom, basement, and second floor hallway, wiring for sub units in all bedrooms and the study, a Cat6 drop in every bedroom, Cat5e in every bedroom, coax in every bedroom, a Cat5e/Cat6 drop in the kitchen and study, and two Cat5e/Cat6 drops in the basement, along with more coax. Cat5e at the front and rear entrance for a camera, Cat5e on the side for a camera if it's an end-unit, and Cat5e at the intercom drops in the kitchen and second floor hallway for a flush mount monitor next to the intercom.
Customization is available preconstruction and midconstruction, but if you don't specify (and pay for) anything special, that's what you get.
This integrator has two crews that can completely wire a house before lunch and another before quitting time. All townhouses built by this developer are built to the exact same floorplan, so the crews know exactly where all the drops are and exactly where the integrator prefers his runs and chases to go. They install rough-in rings and blank plates in some spots, but in others, they simply wrap the wire up and leave it for the sheetrock crew to bury if the home buyer does not end up prepaying for the equipment. The finishing crew can install a full suite of equipment in half a day, assuming no customizations. But even if the home buyer waits a year or two to pay for the alarm or the intercom, cutting open the walls takes them just a few minutes because they know without looking exactly where to cut. One of the nice things about this particular integrator's mild OCD is the fact that his installs are perfect and identical, every time.
As far as I know, they do not wire for WAPs or USB.
