A Digital Video Recorder (DVR) takes video signals from security cameras and converts the video stream into a digital format for storage on an internal hard drive. A DVR also provides a user interface to remotely manage many functions of the video files and cameras, including motion detection and pan/tilt/zoom features. At a minimum, a DVR should allow multiple users to view multiple cameras remotely. Effective video compression is one of the most important considerations when looking at DVRs. The most common video compression formats used in video surveillance are M-JPEG and MPEG-4. While proprietary compression technologies may provide superior quality, their lack of compatibility with Windows-based operating systems may become an issue for archival purposes. Issues of frame rate, resolution, disk size, motion detection, compression ratio, and camera noise all affect the storage capacity of a video surveillance system. High resolution is ideal to capture details, while high frame rates are needed to capture events. Frame rates of less than 20 fps tend to be jerky, while rates of 20 - 30 fps can be adequate for most surveillance needs. |
