Hikvision AcuSense 32-Channel NVR
Designed for professional CCTV and IP camera installations, the DS-7632NXI-K2(D) supports up to 32 IP camera inputs. Its AcuSense capabilities help improve security monitoring by focusing attention on relevant events and reducing the amount of manual effort required.
The NVR supports intelligent analytics, perimeter protection, target recognition and Motion Detection 2.0, making it suitable for a wide range of commercial, industrial and security applications.
High-Resolution Recording and Playback
With support for recording resolutions up to 12MP, the NVR can manage high-detail surveillance footage from compatible IP cameras. Its decoding capability supports multiple combinations of high-resolution video, allowing users to balance image quality and the number of streams being viewed or played back at the same time.
Key video capabilities include:
Efficient H.265+ Video Compression
Support for H.265+, H.265, H.264+ and H.264 video formats provides compatibility with a wide range of IP cameras while helping manage network bandwidth and storage requirements. H.265+ compression is particularly useful for installations that need to retain surveillance footage efficiently.
Flexible Display and Connectivity
The Hikvision DS-7632NXI-K2(D) provides a 4K HDMI output with support for up to 3840 x 2160 at 30 Hz, along with a VGA output supporting up to 1920 x 1080 at 60 Hz. HDMI and VGA can operate as independent outputs, allowing different displays to be used for monitoring purposes.
Connectivity includes a self-adaptive Gigabit Ethernet interface, USB ports for compatible peripherals and alarm inputs and outputs for integration with supported security equipment.
Storage and Network Support
Two SATA interfaces allow the NVR to accommodate up to 16TB per hard drive, providing substantial storage capacity for surveillance recordings. The 10/100/1000 Mbps RJ-45 network interface supports high-bandwidth IP camera connections and network communication.
