THE DIGITAL VIDEO RECORDER A Digital Video Recorder Records Video And Stores data as digital. It can be a piece of computer hardware or software. The recorded video can be from a variety of sources, such as a DVD, analog television, cable television cables, camcorders or other sources. In some ways, a digital video recorder can be thought of as performing the same function as a VCR. However, the recorded video is stored in a digital format such as AVI or MPEG as well as the data on a DVD. recorded content can be indexed, searched, and manipulated in other ways that a video tape can not.

In a DVR security system, a closed circuit video camera is connected to a DVR or PC capable DVR device. Like recording video (and possibly audio) television cameras, it is routed to the DVR device by a cable system. The transmitted video can be routed to display monitors, through a network to another device, or converted to a digital format and stored. All archived, or stored, video information is “stamped,” which means it is labeled to indicate the time and date it was recorded and which camera provided the information. This allows people easier access to both archived and real-time security data. ADVANTAGES OVER TRADITIONAL METHODS Although the primary function of a DVR security device is to manage and store entry of surveillance cameras, it has many additional security applications. The cameras can be controlled remotely through the DVR device, allowing the user to increase, pan or rotate the field of view of the surveillance camera. Events such as an alarm from deluxesurveillance.com being triggered can be integrated into the video data as it is stored, thus allowing events to be searched and easily accessed after the fact. Finally, some systems have the ability to detect motion by monitoring video data. The motion detection and event stamping capabilities of such systems remove much of the monitoring and management involved in surveillance personnel, enabling them to work more efficiently. The sophistication of DVR security systems has progressed substantially in recent years, and there is little doubt future systems will play even more impressive functionality.
