A - DVR is a Digital Video Recorder, like digital cameras, digital camcorders, etc. This type of format is far more superior and more powerful than analog recording. Analog devices need more information to reconstruct a good image and have a tendency to smear an image, thus making more difficult to catch a thief. A digital image is clear, easier to store, is easily compatible to your computer and the internet. DVR's have the advantage of being able to have a perfect picture. It doesn't matter if you are recording at 30fps or 1fps they are all digital images.
