commercia_video_recordersDigital Video Recorders (DVR's) and Network Video Recorders (NVR's) are used to store CCTV footage and are a vital part of any surveillance system.

DVR's are used in analogue CCTV systems, NVR's (often referred to as Servers) are used in IP (Internet Protocol) Video systems. Hybrid Video Recorders can accommodate both analogue and IP  cameras. They are usually the heart of the CCTV system as they process and store images obtained from the cameras which are connected directly to it. The Video Recorder provides inputs for cameras and outputs for monitors and PC integration.

Video Recorders offer continuous recording to their internal hard drive, usually retaining footage for an excess of 30 days. The storage capacity is usually anywhere between 500GB (Gigabytes) & 100 TB (Terabytes).

The Video Recorder 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 Recorder in this way is vital for optimising storage capacity.

DVR's and NVR's can usually accommodate between 4 and 16 cameras, however multiple recorders can be used for larger applications, allowing a single CCTV system to accommodate hundreds or even thousands of cameras.  It is important when installing a CCTV system to take future expansion into account and ensure you choose the right Video Recorder to accommodate current cameras plus any extra cameras required at a later date.
