Our software (www.bluecherrydvr.com) is not based on Zoneminder, or any other open source application. It's custom built for commercial applications that require both a stable operating system and software. The software supports audio and video from our line of MPEG-4 and H.264 (coming in August, 2010) hardware compression cards.
