A dvr or digital video recorder functions a lot like a vcr, except it uses a hard drive to record, as opposed to videotapes. This means that there aren't any tapes to cue, and there is more recording time available. Like modern vcrs, users of digital video recorders can record television shows by entering information such as channel, time, and date into a recording menu. On vcrs, the menu is provided by the device itself, whereas the dvr obtains a menu from a remote server. In order to connect to a remote server, a dedicated phone line or high speed internet connection is needed, along with internet service.
there are many advantages to having a digital video recorder. First, the image quality is considerably better than vcr recordings, and is always consistent. Digital also allows for video archiving and transfer of video data to cd-rom or cd-rw. The convenient search function allows users to quickllocate the show, or specific scene, that they want to watch. A digital video recorder can be programmed to record an entire season of a television show, and it is even possible to watch the first half of a show while the dvr continues to tape the second half.

Ip cameras are closed-circuit television (cctv) cameras that utilize internet protocol to transmit image data and control signals over an fast ethernet link. As such, ip cameras are also commonly referred to as network cameras. Ip cameras are primarily used for surveillance in the same manner as analog closed-circuit_television. A number of ip cameras are normally deployed together with a digital video recorder (dvr) or a network video recorder (nvr) to form a video surveillance system. The terms ip camera and network camera are most commonly used to refer to surveillance cameras with a fast ethernet interface. In this context, the term ip camera does not include gige_vision camera, which is a machine vision camera with a gigabit ethernet interface.
