Stand-alone DVR makers emphasize step up to HD

Products adopt H.264 or MPEG-4 compression.


  • Improving resolution quality: Products adopt H.264 or MPEG-4. Mainstream models largely support D1 or 960H resolution, while advanced units deliver 720p or higher. 
  • Adding value: More releases are equipped with a Web server and multilanguage menu. One to eight 3.5in SATA HDD slots are used for storage backup. Some units may support eSATA and RAID.
  • Enhanced performance: While basic models run on Hisilicon’s Hi351x, Fullhan’s FH8735 or Grain Media’s GM818x ASIC, more midrange DVRs use ASIC with HD encoding capability. High-end units mostly employ DSP with HD encoding/decoding, with some based on TI’s DM816x or DM64x that enables intelligent video analysis.
  • A/V I/O: Four to 32 channels can be supported. Entry-level DVRs feature CIF resolution. HD-SDI interface is available in some advanced models. Low-end models come with one or two CVBS ports. Pricier variants have additional VGA and HDMI ports. For audio I/O, there is a BNC port.
