Huh it was hard for me to find CD-rom device to finally get this soft for my Chinese CCTV DVR system, names as H.264 on a box and nothing elese - no manufacturer, model number, etc. The DVR viewers from internet could not help me :( So I'm wanted to share this with you. This DVR CMS Software works on both of mine China H.264 CCTV devices. So hope it will help you too. Free download Generic DVR CMS Software.
