My company has recently purchased a dvr made by rifatron called the "imdvr 1648" which records at, i believe 30 fps and stores up to 14 days on whatever number of cameras we have installed on there. the only problem is, after we have used up the 14 days it recycles the storage space. if there is coverage of an event we need to have preserved for evidentiary purposes, how can we go about transferring it onto an external storage medium (for example: dvd, vcd, or vhs)? also the there is no "video-out" outlet, but rather where there should be one is an xj-45 outlet and an ethernet outlet. i am wondering if there is a way to hook up a stand alone dvd-recorder or (must it be?) networked to a pc with dvd-burner preinstalled? any information you could supply would be of great help to me, the young guy in the department with SOME computer knowledge. below is a link of the product. http://www.rifatron.com/product/imdvr-1648.htm
