Hikvision DS-7204HGHI-K1 Turbo HD DVR

The Hikvision DS-7204HGHI-K1 is a compact 4-channel Turbo HD DVR designed for surveillance systems that need flexible analog camera compatibility, intelligent motion filtering, and efficient video storage. It supports HDTVI, AHD, HDCVI, CVBS, and IP video sources, making it suitable for both existing coax-based systems and hybrid surveillance upgrades. Deep learning-based Motion Detection 2.0 can distinguish human and vehicle targets to help reduce unnecessary alerts caused by objects such as leaves and lights. H.265 Pro+ compression, smart playback search, Hik-Connect support, and storage of up to 4 TB provide practical recording and remote-management capabilities for everyday security applications.

Ideal Applications & Common Uses

Based on the capabilities documented in the datasheet, this DVR is suited to applications such as:

  • Small residential video surveillance systems
  • Small offices and retail locations using up to four analog surveillance channels
  • Existing coax-based CCTV systems being upgraded to HD analog cameras
  • Hybrid surveillance installations requiring support for analog and compatible IP video sources
  • Locations where human and vehicle motion classification can help reduce unnecessary motion alerts
  • Surveillance systems requiring remote connectivity through Hik-Connect
  • Installations requiring audio over compatible coaxial camera connections
  • Systems requiring local HDMI or VGA monitor output
  • Applications requiring up to 4 TB of internal surveillance storage

Datasheet Notes

1080p Lite Frame Rate
The datasheet's Key Feature section states "up to 1080p Lite @ 15 fps encoding capability," while the detailed Recording specification lists 1080p Lite at 25 fps (P) / 30 fps (N). Both values have been preserved rather than silently reconciling the discrepancy.
Working Temperature
The datasheet prints the operating range as -10 °C to 55 °C (14 °F to +31 °F). The Fahrenheit value has been preserved exactly as printed in the source rather than corrected.
