Cheap system update for CCTV control room

[AustinN360]

Hi guys. I work for a small security company based in the UK and we monitor CCTV cameras for several companies. With the upcoming retirement of Windows 7 we are looking to upgrade our aging systems to something that will run our software better and smoother than what we are currently working with. We are currently running 3 computers each with AMD A8-3850 with Radeon HD graphics @ 2.90GHz, 16gb ram and twin ATI Radeon HD 5400 graphics cards. What we need is something that will run 5 monitors each and up to 100 CCTV displays per system. We use Qvis NVMS-1000, Hikvision IVMS4200, Zone alarm, a generic H.264 CMS software and Internet Explorer at present.

Also on the subject of CCTV. We have 2 building sites and an additional 3 mobile CCTV vans that all run live stream via 3g data sims (4g in some areas where its available) and would like to find out the optimal camera resolution and bitrate settings that will give us uninterrupted live coverage without any data dropouts and save having to reset the camera devices every couple of hours while on shift.

If anyone can help with pricing for a decent enough cheap system or if you can help with the data issues then all help will be appreciated.

Thanks.
