Access Control Design - Do You Install Controllers In An IDF Or At The Edge On The Secured Side Of The Door?

Do you prefer to group your door controllers in a single location - like an IDF or do you install them at the edge on the secured side of the door?

Does client IT actually provide UPS capacity for the door controllers if they are POE+?

Does it make more sense to locate a power supply (Altronix, etc) in the IDF and run a 16/2 out to each edge controller?

Which is more cost effective?

What do installers prefer?
