KaktusJaque 0 Posted January 28, 2017 Hello, I had a couple questions and wanted to get your thoughts on. I have a retail client that contracted me to replace their old 24v analog DVR/cameras with a newer 12v AHD system. The old systems had a camera watching the front registers, and above the registers was a PVM monitor showing the front counter in the display. These older PVMs are not working with the new AHD system and from what I can gather, the reason is that they are analog PVMs and wont work with an AHD system. Is this correct? Are there PVMs that I can install that will work with my AHD system? My DVRs have a CVBS bnc on the back, can this be used to a PVM to display the front counter?
