06. Advantages of Digital CCTV
| The CCTV digital age has really arrived
More and more people are moving to DIGITAL BASED CCTV Systems over the conventional analog VCR based systems. The benefits of using a digital system, is that it allows the user to replace their switching unit, monitor and time-lapse recorder with one centralized system, which they can access and control from several locations. Because the system is automated, one does not have to swop or replace any video cassette tapes, allowing minimum intervention from the system controller.
These systems can record video images on the HDD, depending on capacity, for several weeks. A digital system allows the user to instantly retrieve relevant data. There is no longer a need for screening through hours of video tape to find a single frame of video. Data is stored in a database which can be searched by camera, time, date, alarm-activation or motion. This saves the user time in identifying the target.
Even at the most basic level digital video images are superior to video recorded on analog systems. Sharp, crisp images are stored which can be viewed over and over again without image deterioration.
Yet another advantage of digital systems is their flexibility of recording modes. Recording can be done by schedule (ie. time or date), alarm activation or via smart motion detection.
