Digital Video Recorders
Digital Video Recorders (DVR's) have replaced the use of old technology of VCR's, eliminating the need for changing tapes on a daily basis and allowing functions such as viewing from your PC.
The DVR is usually the heart of the CCTV System. It processes and stores images obtained from the cameras which are connected directly to it. The DVR provides inputs for cameras and outputs for monitors and PC integration.
DVR's offer continuous recording to their internal hard drive, usually retaining footage for in excess of 30 days. The storage capacity is usually anywhere between 250 GB (Gigabytes) & 1.5 TB (Terabytes).
The DVR is able to process information such as movement or motion within the images, which increases the amount of recorded frames per second when motion is detected on the image. Configuring the DVR in this way is vital for optimising storage capacity.
DVR's can usually accommodate between 4 and 16 cameras (channels). Multiple DVR systems can be used for larger applications. It is important when installing a CCTV system to take future expansion into account and ensure you choose the right DVR to accommodate current cameras plus any extra cameras that might be required at a later date.
