DS-7616NXI-K2/16P(E) specification sheet

Overview:

The Hikvision DS-7616NXI-K2/16P(E) is a 16-channel PoE 4K AcuSense NVR designed for reliable IP video surveillance in homes, offices, commercial properties and other security installations. With built-in PoE connectivity, intelligent video analysis and support for high-resolution IP cameras, it provides a practical way to manage, record and review multiple surveillance cameras from a central system.

Description:

The Hikvision DS-7616NXI-K2/16P(E) combines 4K video recording with Hikvision AcuSense technology to help reduce false alarms and minimise the amount of manual monitoring required. Perimeter protection, facial recognition and motion detection provide additional tools for identifying relevant security events, while AcuSearch helps users quickly locate important footage during playback.

The integrated 16-port PoE design makes installation simpler by allowing compatible IP cameras to receive power and network connectivity directly from the NVR. Automatic camera connection and configuration also help streamline deployment, making this model suitable for installations where multiple PoE cameras need to be connected to one central recorder.

With support for H.265+, H.265, H.264+ and H.264 video formats, the NVR can efficiently handle different camera streams while helping to optimise storage usage. It supports up to 160 Mbps incoming bandwidth and provides flexible decoding performance for different camera resolutions.

Features:

Intelligent Hikvision AcuSense Security
AcuSense technology is designed to improve surveillance efficiency by helping distinguish relevant security events and reduce unnecessary alerts. Perimeter protection can assist with monitoring defined areas, while facial recognition and motion detection provide additional options for intelligent video surveillance.

AcuSearch makes reviewing recorded footage more efficient by helping users find relevant events without having to manually search through long periods of video.

16-Channel PoE Camera Connectivity
The recorder supports up to 16 IP camera inputs and includes 16 integrated 10/100 Mbps PoE network ports. Compatible PoE cameras can be connected directly to the NVR, reducing the need for separate PoE equipment in many installations.

Key connectivity and recording capabilities include:

• 16-channel IP video input
• 16 x RJ-45 10/100 Mbps PoE ports
• 1 x RJ-45 10/100/1000 Mbps self-adaptive Ethernet port
• Up to 160 Mbps incoming bandwidth
• Automatic camera connection and configuration
• 16-channel synchronous playback

4K Video Output and Playback
The Hikvision NVR supports high-resolution video monitoring with an HDMI output capable of 4K resolution at up to 30 Hz. A separate VGA output supports up to 1920 x 1080 at 60 Hz, allowing flexible connection to compatible displays.

The system can decode up to 3-channel 12 MP, 5-channel 8 MP, 10-channel 4 MP or 16-channel 2 MP video, depending on the camera resolution and decoding requirements.

Efficient Video Compression
Support for H.265+, H.265, H.264+ and H.264 video formats provides compatibility with a wide range of Hikvision and compatible IP cameras. More efficient compression can help reduce storage requirements while maintaining suitable video quality for surveillance recording.

Storage and Recording Capacity
Two SATA interfaces are provided for internal hard drives, with support for up to 16 TB capacity per HDD. This gives the recorder substantial storage potential for continuous or event-based surveillance recording, depending on the installed drives, camera resolution, frame rates and recording settings.

The NVR also includes 4 alarm inputs and 1 alarm output, providing additional integration options for compatible security devices.

Audio and Alarm Connections
The DS-7616NXI-K2/16P(E) includes audio connectivity for surveillance and communication applications. It provides one RCA audio output and one RCA two-way audio connection, along with support for up to four IP speaker inputs.

Ports and Connections
For straightforward installation and system integration, the recorder provides:

• 2 x SATA interfaces
• 1 x USB 2.0 port
• 1 x USB 2.0 port
• 4 x alarm inputs
• 1 x alarm output
• 1 x RCA audio output
• 1 x RCA two-way audio
• 4 IP speaker inputs
• HDMI and VGA independent outputs

Part Number and Model
This Hikvision 16-channel PoE AcuSense NVR is identified by part number / SKU DS-7616NXI-K2/16P(E). It is a suitable choice for users looking for a centralised 4K IP camera recording system with integrated PoE, intelligent surveillance functions and flexible storage options.

Why Choose This 16-Channel Hikvision NVR
For installations requiring up to 16 PoE IP cameras, the DS-7616NXI-K2/16P(E) offers a combination of high-resolution recording, intelligent event detection, integrated networking and efficient video compression. Its AcuSense capabilities can help reduce unnecessary alerts, while AcuSearch provides a faster way to locate relevant recorded footage.

The integrated PoE ports also make it easier to build a complete IP surveillance system without necessarily requiring a separate PoE switch, making this NVR a practical option for residential, business and commercial security applications.
