| WHY MPEG? |

VELTEK digital products, such as the M-DVR4, use the MPEG compression method ( in the case of the M-DVR4, the MPEG-2 compression method is used). What exactly is MPEG? MPEG stands for (Moving Picture Experts Group). Unlike other digital compression methods such as JPEG or Wavelet which were developed to compress still images, MPEG compression uses extremely sophisticated algorithms to encode audio-visual information in a digitally compressed format, resulting in much smaller file sizes than those created using either the JPEG or the Wavelet methods. MPEG's multi-stream capability allows you to compress numerous independent video channels simultaneously (at lower frame rates) without breaking the important interframe dependencies for any of them. The number of independent video channels compressed is determined by the specific MPEG algorithm. MPEG compression...... • Allows you to capture large amounts of high quality video data that can be easily stored, achieved or browsed. • Allows independent and precise control of each camera, smooth expandability of a number of monitored channels, storage space, etc. • Makes possible quick and precise random access to the recorded video and automatic logging. • Can be easily transmitted over existing network links to enable remote video monitoring, data storage/retrieval and station management from one or more computers running Windows 95/98/NT/2000™.
