Hikvision DS-7232HGHI-M2 32-Channel 1080P DVR

The Hikvision DS-7232HGHI-M2 is a high-performance 32-channel DVR engineered to provide advanced video surveillance management with cutting-edge features, flexible recording options, and intelligent motion detection capabilities. Designed for medium to large-scale security installations, this DVR combines deep learning-based analytics, multi-format camera support, efficient storage compression, and powerful network capabilities, making it an ideal choice for professional-grade security systems.

Intelligent Motion Detection 2.0

One of the standout features of the DS-7232HGHI-M2 is its deep learning-based Motion Detection 2.0, enabled by default on all analog channels. Unlike conventional motion detection, this enhanced system is capable of distinguishing between humans and vehicles, dramatically reducing false alarms caused by irrelevant objects such as animals, leaves, rain, or lighting changes.

This intelligent classification helps security teams focus on real threats and events, minimizing wasted time and resources. Additionally, users can benefit from quick search by object or event type, allowing for efficient playback and incident analysis. This capability ensures faster investigations and improved situational awareness.

Recording and Video Compression

The DVR supports multiple video compression technologies, including H.265 Pro+, H.265 Pro, H.265, H.264+, and H.264. These advanced codecs reduce storage consumption while preserving video quality, enabling longer recording times without sacrificing clarity.

Encoding resolution options include 1080p Lite, 720p, 720p Lite, WD1, 4CIF, VGA, and CIF, providing flexibility depending on camera type and monitoring requirements.

• Main Stream:
  • For 1080p stream access: 1080p Lite/720p Lite/WD1/4CIF/VGA at 15fps; CIF at 25fps
  • For 720p stream access: 720p/WD1/4CIF/VGA at 15fps; CIF at 25fps
  • For SD access: WD1/4CIF/VGA/CIF at 25fps
• Sub-Stream: CIF/QVGA at 15fps

The supported video bit rate ranges from 32 Kbps to 4 Mbps, balancing bandwidth efficiency with video quality. While dual-streaming is not supported, the system ensures stable and reliable recording suitable for high-demand environments.
