Technical Specifications

Hikvision DS-7224HQHI-K2 / DS-7232HQHI-K2 Turbo HD DVR

Designed for large surveillance systems, the Hikvision DS-7224HQHI-K2 and DS-7232HQHI-K2 support 24 or 32 analog camera channels while allowing additional IP cameras for future expansion. Multi-format video compatibility makes it easier to integrate HDTVI, AHD, HDCVI, CVBS, and compatible IP cameras into one system.

H.265 Pro+ compression helps reduce storage requirements, while two SATA interfaces support up to 10 TB per hard drive. Smart search, configurable analytics, 4K HDMI output, and Hik-Connect support provide practical tools for recording, reviewing, and remotely managing a high-channel-count security installation.

Ideal Applications and Common Uses

  • Large retail stores and supermarkets requiring many camera channels.
  • Warehouses, distribution centers, and industrial facilities.
  • Office buildings and multi-floor commercial properties.
  • Schools, campuses, and institutional facilities.
  • Hotels, apartment buildings, and multi-unit properties.
  • Upgrading an existing coaxial surveillance system while retaining installed cabling.
  • Hybrid systems combining analog HD cameras with compatible IP cameras.
  • Sites requiring centralized monitoring, smart video search, and remote access.

Important Configuration Notes

Enabling Enhanced VCA Mode increases the number of channels available for line-crossing and intrusion detection, but disables 2K/4K HDMI output and 4 MP signal input.

Enhanced IP Mode may conflict with perimeter-protection events or other functions. Consult the applicable user manual before enabling this mode.

Hikvision DS-2CE10DF0T-PFS 2MP ColorVu Audio Fixed Mini Bullet Camera

The Hikvision DS-2CE10DF0T-PFS combines full-HD 1080p video, 24/7 color imaging, and a built-in microphone in a compact mini-bullet design.
