NVR Addition

Manufacturer IndigoVision has launched an addition to its range of Network Video Recorder (NVR) products.

NVR1.5 has a ’hot-swappable’ removable hard disk drive, which can be replaced without interrupting recording – it takes 20 seconds to swap discs, the makers report. Any number of disks can be swapped out providing increased storage capacity. Typically a single disk will store four months of continuous full frame-rate high quality digital video, according to the firm. Disks can be moved between any NVR1.5 on the network allowing, for example, remote recording with archiving and playback at a central location. The product provides fault-tolerant solutions for mission-critical applications, the makers say. It has built-in redundant power supplies and network connections and recordings can be mirrored to multiple NVRs around the network.

The product is designed to work with IndigoVision’s IP-Video technology and provides significant benefits, it is claimed, over traditional Digital Video Recorders (DVRs). The firm says it is important to differentiate between DVRs and NVRs, as both are often termed ‘digital’. A DVR digitally compresses analogue video feeds and stores them on a hard disk, the term ‘digital’ referring to the compression and storage technology, not the transmitted video images. The DVR therefore has to be located near the analogue feeds, typically next to a matrix. In contrast an NVR stores digital images directly from the IP-network, and can be located and distributed anywhere on the network. IndigoVision’s NVRs overcome the scalability issues associated with stand-alone DVRs, it is claimed.
