Technical Specifications

Hikvision DS-7324HQHI-K4 / DS-7332HQHI-K4 Turbo HD DVR

Manage a large, mixed-camera surveillance system from one high-capacity recorder. The Hikvision DS-7324HQHI-K4 and DS-7332HQHI-K4 support HDTVI, AHD, HDCVI, CVBS, and IP cameras, making them practical choices for expanding an existing analog system without immediately replacing every camera.

With H.265 Pro+ compression, four SATA bays, an eSATA interface, 4K HDMI output, smart video analytics, and support for up to 40 or 48 IP cameras, this series is designed for demanding commercial surveillance environments that require extensive coverage and efficient storage.

Ideal Applications and Common Uses

  • Large retail stores: Manage extensive camera coverage while using POS-triggered recording and transaction-information overlays.
  • Warehouses and distribution facilities: Connect numerous cameras and use large-capacity storage for extended recording requirements.
  • Office buildings: Combine analog and compatible IP cameras while monitoring entrances, corridors, parking areas, and shared spaces.
  • Schools and campuses: Centralize surveillance across environments requiring 24 or 32 analog channels and additional IP-camera expansion.
  • Hotels and multi-area properties: Monitor many public and operational areas from one recorder with 16-channel synchronous playback.
  • Existing coaxial-system upgrades: Retain compatible coaxial cameras while adding newer HDTVI, AHD, HDCVI, CVBS, or IP cameras.
  • Long-distance camera installations: Suitable where compatible HDTVI signals must travel up to 800 m at 1080p or 1,200 m at 720p.
  • High-capacity surveillance systems: Four SATA bays and eSATA support make the series suitable for installations with substantial storage requirements.
  • Remote monitoring environments: Hik-Connect, DDNS, and support for up to 128 remote connections enable network-based access and management.
  • Sites requiring event-based monitoring: Line-crossing, intrusion, and sudden scene-change detection help operators identify specified video events.
