I have a number of Kodicom PC systems installed at client sites using 4.13 P8 or P13 and 4400 capture cards all genuine. My question is can i install 5.2 software form dvr-usa and what real advantages would my client get from this. Will it allow us to integrate IP cameras and if so what IP cameras are supported. it there any way to get a demo copy of software to fully evaluate using existing board. We want to move out clients forward without having to scrap everything they already invest in.
