Digital Video Recorder
Digital video recorder, or DVR, is either an electronic device or application software that records video onto a computer storage device. DVRs are usually hooked up to a monitor to view the video feed, and an external storage device, such as a hard drive, flash drive, or memory card, to record video.
DVRs and TVs
DVRs have a wide assortment of uses. They are most commonly used as modern day VCRs. They are hooked up to TV sets and used to record TV shows. Instead of recording onto VHS tapes as the VCR did, DVRs record onto hard drives or DVD-RWs.
A cool feature for DVRs is the ability to quickly skip over commercials, rewind during a TV show if you missed a scene, or even watch half of a show and let the DVR record the second half so you can watch later. Most DVRs need some sort of network connection, via Tivo or DirectTV services to do these functions.
DVRs and CCTV
DVRs also go hand-in-hand with CCTVs (closed-circuit television). Many survellience cameras must hook into DVR systems to record video, although many modern day cameras have built in DVRs and record onto SD cards or built-in hard drives.
