CCTV DVRs are based on computer technology and as such they record images on an internal hard drive. With these recorders you do not need to change tapes or video cassettes and as all the recording are done on the HD video images are always as good as day one.

DVRs normally come with 3 different specifications which obviously affects the price. JPEG,  MPEG3 or H264

if you are only interested in local onsite viewing, then you can go for the cheaper Jpeg DVRs. these DVRs produce good images and different makes have different features which of course is reflected in the price again. , for example , some have remote control, on some you can back up your CCTV evidence and video images on USB memory sticks, some have CD writers, some you can only make copies of your recording via connection to a pc.

If your intention is to view the cctv images over the internet then you will need to go for an Mpeg4 or H264 compression DVR. These offer a better compression rate which in turn offers faster movement of images over the internet. These CCTV DVRs normally come with more features for back up, etc and of course this is reflected in their price which is higher than Jpeg DVRs. These CCTV DVRs specially H264 compression ones enable you to record more video images  on a smaller size hard drive than Jpeg DVR,

Basically, given a certain size of hard drive, Mpeg4 offer twice the recording length of Jpeg and H264 offers twice the recording length of Mpeg4. Therefore a H264 CCTV DVR offers you four times the recording time of a Jpeg recorder.

The XDH Compact offers the best in terms of performance and multiple monitor outputs. No other DVR's allow you to use VGA and standard BNC outputs at the same time. If you are looking for a commercial DVR, thats easy to use and offers a superb CMS software solution allowing for multiple remote logins and Internet connectivity. Make no mistake this is a Real-Time Matrix DVR that offers a host of advanced but easy to use features. It now comes with duel streaming as standard basically meaning that you will get a faster network experience than many similar DVR recorders, as one processor is dedicated to remote data streaming. This DVR also offers mobile phone viewing with apps for the Iphone and Windows mobile.
