During my time as an integrator, there was always a select few manufacturers that we would use products from. Whether it be for access control, IP cameras, Intercom, Intrusion, VMS platforms and the sort.

However, there would occasionally be instances where something "new" would be required, and could sometimes make the 1-2 hour service call 3-4 hours (per device/platform), if not longer. Of course, after seeing and using it once, an adept tech would then (hopefully) understand the basic functionality of the device(s). However, if said tech was unavailable to service an "outside" device, then the usual quick call for tech A becomes a learning experience all over again for tech B, with calls to support and, hopefully, tech A can provide support.
