DVD or DVR? The two are different in some ways. To watch a cctv footage on a DVD you have to have CD/USB record of the footage which you have burned in either a laptop or a desktop computer. On the other hand, a DVR lets you record and watch a cctv footage directly without having to convert any files. The benefit of DVRs is that it lets you store large files, for example 1week of surveillance footage, without having to delete previous footage. There are also DVRs such as the Everfocus ECOR 264-4d2 from USAsecuritysytems.com that allows you to record and play 4 cameras at the same time.
