In CCTV security system terms, DVR stands for Digital Video Recorder, it is used to digitally record images from the security cameras.

There are different ways to record images from your cameras. 

In the old days, we used video cassette recorder (VCR).  The bad thing with VCR is, you need many video tapes.  The most economic option is using a 180 mins cassette tape, with "long play" recording mode, you will record 6 hours on each tape.  You need 4 video tapes for a 24 hour day's recording, that is, if you have someone physically change the tape, otherwise it just stops when one tape is finished.   When it comes to searching the footage, it is another huge task trying to find the right tape from the pile of tapes, then play the 6 hour tape, hoping the FF and REW keys on the remote don't get too tired.

With the digital DVR method, your task becomes much easier. You record the camera images onto a hard drive, no need to change video tape any more, then when you play back the recording, the whole month's data is on the single hard disk, you may search by date, time, etc.
