Constructing a Test Method to Evaluate Stable DVR System
Security systems using a digital video recorder (DVR) are an increasingly popular security product in the surveillance systems market. These DVR-based security systems include software and hardware and generally have six modules, including one each for the input signal channel, the recording function, the playback and display functions, communication and remote transmission, system control, and system security modules. Software and hardware are continuously changing and evolving. Accordingly, purchasers have difficulty in discriminating between new technologies and in determining which DVR-based security system is best suited to their surveillance and security needs, or both. In this study, gray situation decision-making (GSDM) is used to evaluate DVR-based security systems based on several quality performance characteristics. Finally, a case study is presented to demonstrate the effectiveness of the proposed GSDM method.
