It is apparent that still there is a great demand for analog surveillance systems. Though the system is cost-effective, the analog systems are still being used for many surveillance applications. The IP systems are indeed more advanced than the analog systems. In earlier analog systems, the videos were recorded and stored in tapes which itself has many limitations. Now with the introduction of DVRs, a new way of managing the videos has taken place. In reality, DVR or digital video recorder convert analog signals to digital and it allows to view and manage the videos in digital format. DVR is a good solution for those who wish to view the videos in a digital format by staying with the analog systems itself.
