Hybrid DVR upgrades boost resolution, capacity

Makers are improving video transmission and storage capacity to support widening demand for HD surveillance.



  • Enhanced recording resolution, throughput: The latest releases support 16-channel D1 analog and 4-channel 1080p or higher IP recording, exceeding the mainstream 4-channel D1 analog and 1-channel 720p IP video input. Advanced models record in 5MP. Makers are adding 960H-compliant sensors nd HD-SDI ports to facilitate migration to HD. Upscale versions have dual 1,000Mbps ports to realize 32-channel 720p IP input.
  • Improved storage capacity, data management: Mainstay variants integrate multiple HDD bays to support more than 32TB. To strengthen data security, suppliers add RAID, hot-plugging, -swapping or -sharing, group management and virtual configuration.
  • Ensuring compatibility: To enable interoperability with most CCTV and surveillance devices, suppliers adopt H.264, MPEG-4 and AVS, and solutions from Sony, Samsung, Panasonic, Sanyo and Axis. Some companies are considering ONVIF and PSIA compliance to interface with IP cameras.
  • Expanding supplier base: From about 50, the maker population is expected to breach the three-digit mark in coming months as the line continues to mature.
