Our EyeCUTV systems utilize MPEG-4 and MPEG4/H.264 hardware compression technology allows for the maximum recording time available before data-rewrite is required.  Our systems provide between 30 and 180 days of recording and when your hard drive is near the re-write time you receive a warning. So as to assure you can back-up any video you desire before data loss.  There are no video tapes to worry about and with our CDRW and DVD Drives, we make it simple to back-up and archive your data.
