High-performance H.264 compression
The Dallmeier DLS series comprises high-performance stand-alone H.264 audio and video recorders with up to 16 channels. The DIN EN 50130-4 certified recorders allow for real-time recording of all channels. Apart from the standard version, a Plus variant is also available. The latter is optimised for recording with a high frame rate at high resolution.
As in many other sectors the requirements on standardised procedures for the compression of images have risen significantly. This is true for the quality of pictures as well as the flexibility of the compression procedure itself. With H.264 a new standard for video compression has been created, basically comparable with MPEG and fulfilling high requirements.
The DLS series offers a high performance capability and reliability, which are also demonstrated by the use of the H.264 codec standard. The H.264 standard combines unsurpassed image quality with particularly high data compression (reduction of the bit rate by 37 per cent compared to MPEG-4 and by 64 per cent compared to MPEG-2). The advantages are cost reduction, lower demand for storage capacity, less network load and longer recording times. As one of the first manufacturers of digital video recorders Dallmeier has integrated the H.264 algorithm into its product development for the CCTV/IP area and continues to prove its innovative strength and technological leadership.
