Overview

Hikvision DS-7632NXI-K2 32 Channel AcuSense 4K NVR
The Hikvision DS-7632NXI-K2 is a professional 32 channel 1U network video recorder designed for reliable IP camera surveillance in homes, businesses, offices, retail environments and larger security installations. With 4K video support, AcuSense technology, advanced video analytics and up to 32 IP camera inputs, it provides a practical solution for managing and monitoring a multi-camera security system from a central NVR.

Description

The DS-7632NXI-K2 combines high-capacity network video recording with Hikvision AcuSense technology to help improve security monitoring while reducing the amount of manual work required from operators. AcuSense helps identify relevant security events more efficiently, making the recorder well suited to installations where accurate detection and efficient monitoring are important.

The NVR supports H.265+, H.265, H.264+ and H.264 video formats, helping optimise storage and network bandwidth while maintaining suitable video quality. It can decode multiple channels simultaneously and supports up to 16 channel synchronous playback, making it easier to review footage from several cameras at the same time.

Features

32 Channel IP Camera Recording
With support for up to 32 IP video inputs, this Hikvision NVR can manage a substantial surveillance installation from a single recording platform. Its 256 Mbps incoming bandwidth provides the capacity required for high-resolution network camera streams, including 4K cameras.

The recorder also supports Hikvision security technologies such as facial recognition and perimeter protection, helping provide more intelligent surveillance capabilities when compatible cameras and functions are used.

4K Video Output and Playback
The DS-7632NXI-K2 provides a 4K HDMI output for connecting a high-resolution display, while the VGA output supports up to 1920 x 1080 at 60 Hz. HDMI and VGA outputs can operate independently, allowing greater flexibility when connecting monitoring displays.

Playback support includes up to 16 channels simultaneously, which is useful when investigating incidents across multiple cameras.

Storage and Network Connectivity
Two SATA interfaces are available for installing surveillance hard drives, with support for up to 16 TB per HDD. This provides substantial storage capacity for recorded security footage, depending on the selected hard drives, recording resolution, frame rate and retention requirements.

Network connectivity is provided through a Gigabit RJ-45 Ethernet interface, offering 10/100/1000 Mbps self-adaptive operation for connection to the surveillance network.

Key technical details include:

• Up to 32 IP camera inputs
• Up to 256 Mbps incoming bandwidth
• Up to 16 channel synchronous playback
• HDMI output up to 4K resolution at 30 Hz
• VGA output up to 1920 x 1080 at 60 Hz

• 1 x RJ-45 10/100/1000 Mbps Ethernet interface
• H.265+, H.265, H.264+ and H.264 video decoding
• 1 x USB 2.0 interface
• 1 x USB 2.0 interface
• 4 alarm inputs and 1 alarm output
• 1 channel RCA audio output
• 1 channel two-way audio

Intelligent Surveillance for Modern Security Systems
Hikvision AcuSense technology is designed to improve the efficiency of surveillance systems by helping reduce unnecessary alerts and manual monitoring. Combined with functions such as facial recognition, perimeter protection and motion detection, the NVR is suitable for security installations where intelligent event detection is an important consideration.

The combination of 4K recording support, large storage capacity, Gigabit networking and multiple camera inputs makes the DS-7632NXI-K2 a suitable central recording solution for medium to large IP surveillance systems.
