Sanyo have launched the DSR-5016PA digital video recorder. The new recorder is ideal for CCTV applications as it uses the JPEG 2000 video format that can be compressed to produce very small file sizes. File size is important if the images will be retrieved over an IP network.

The JPEG 2000 format also improves on other image formats in that it reduces the pixelisation that often occurs when images are compressed.

The DSR-5016PA has sixteen camera inputs and one terabyte of onboard storage. If required, additional storage of video images can be achieved via Sanyo`s optional VA-EXH external expansion hard drive unit which offers two terabytes of additional capacity. The recorded images can easily be transferred for evidential purposes onto a DVD or CD via the DSR-5016PA`s integral DVD/CD writer or alternatively onto compact flash or a microdrive.

The recorder can also be set to highlight regions of interest on any given scene that it is recording. The ‘regions of interest’ areas of the CCTV image can have their picture quality enhanced enabling operators to view any area of an image that is of particular interest. This enables the video file to be further compressed as any area that is not of interest can be recorded at a lower resolution. Also available is the ability to alert an operator about pre-defined events by email.
