Current system sufficient?



I’m a tech for a school district that is using grandstream for their dvr needs. We use the gsurf pro software but need something better, if a camera stops recording or disconnects, or hard drive stops recording, or several other issues I have witnessed, there is no way to notify myself of any issue, instead I find out when we want to view video from some time and discover it was never recording for some reason. The only setting os any use is disk full setting but theres a ton of other stuff that is happening. Plus, we’re running a dozen or so cameras on each (we have 3) “server” which is just a dell optiplex 760, so they are very slow. My goal is really just find some other software to manage this stuff, hardware I can figure out. I would rather keep all the existing cameras and all, just need better software. Any thoughts?
