This article looks at how technology has made the concept of constant recording somewhat outdated.
Abstract
There is debate in the electronics industry about the value and best use of digital video recorders (DVRs). One thing that is not in doubt is that, for the first time, DVRs make credible and effective event-based recording a reality for mainstream applications. The management of Closed Circuit Television (CCTV) footage is simplified and the effectiveness of the system enhanced by the use of digital technology. Many DVRs have network compatibility and can be programmed to connect to a remote site, either over a network or a dial-up connection. A copy of the video clip can then be transmitted, allowing security team members to quickly assess the site status. Restricted bandwidth is not a great problem, as the data can be heavily compressed. DVRs with IP connectivity add to the benefits of the system. Reductions in maintenance costs and wasted man-hours searching for video clips is an added benefit.
