I've just started a new job and part of my mandate is to assist in the upgrade of an older digital CCTV system with 64 PTZ and 30 stationary IP cameras connected to a server loaded with Honeywell software multiplexed to eight monitors. We also have an older BNC coax system that feeds to a multiplexer and is basically view only on two separate screens for the two dozen units on that system and that is being upgraded as a part of this project as well.

We have little storage capacity and our system is multi-generational so we've got several PC's networked together and feeding to a central server, we have to switch PC's when we want to access different feeds, record video or access features that are available on one rev. of our software but not another.

My specialty is HVAC controls, but I have experience with CCTV, but that was way back in the analog days, and I am having trouble figuring out options. The cameras are not a problem, they are all good IP cameras, the old coax ones are being replaced with IP PTZ's and about half the existing ones are are megapixel cams, plus we've got a site wide network. The issue is with the head end... I've been aproached with two proposals, a server upgrade and a switch to DVR's. The big downside to the DVR's is that they are hugely expensive compared to a server. I'd also like to stick with the Honeywell software because it seems pretty solid and the operators know it well. We move cams around a lot, and add units regularly, so I'm also looking for cost effective expandability. We're also looking at recording a lot more video so we need much more storage space as well.

It seems like I'm sold on the servers but a friend in the business has told me that the DVR's are the best long term option. I'm getting advise on both sides, but I'm leaning towards a server with upgrade software and several really high capacity hard drives.

Anyone have any thoughts on this ?
