Platinum Support wrote Andrey,    The reason that we ONLY stock the PV-140VPRO cards, not the PV-261 or other cards, is because the software is not really suitable for enterprise-grade applications or installations.  The cards are decent quality, but the software is not really user-friendly nor feature rich for anything but the most basic of installations.    Each software is designed specifically for a particular DVR Card, so there is not any software that we know of that would allow you to run on that DVR Card.  You would pretty much need to replace the DVR Card with a DVR Card/Software from a better system, such as our Alnet DVR Cards.
