Hard Drive Storage
With Hikvision’s Hard Drive Health Detection, NVRs can display
how many storage units are operating correctly.
Redundant Recording
To ensure the safekeeping of security video, the NVR saves two copies of recorded footage:
one copy in the general R/W HDD and the other copy in redundant HDDs.
Main storage
Redundant storage NVR
RAID 0,1,5,6,10
In the case that one of the NVR’s hard drives fails, a replacement
drive can be substituted. The RAID function will supply the
original data by the calculation of the data from the rest normal
hard drives to the new one.
Video Aging
Some video footage requires long-term storage. By imitating characteristics of memory in
the human brain, Hikvision NVRs can optimize the storage technology. This way, the NVR
uses hard disks more efficiently.

File Lock
File lock adds another level of safety to recorded files. When you’ve got footage
that you can’t afford to lose, click on the Lock icon to preserve the recorded file.
Once locked, the file can’t be overwritten during regular, cyclical recording. When
you need more storage space, click again to unlock and overwrite.
Multiple Stream Types
Self-adapting to multi-type code streams, and compatible for different kinds of cameras.
4K Resolution
With 4K decoding and display capability, these NVRs record and reproduce sharper
images with more details and yield more potent security video.

HD Video Display
With 4K decoding and display capability, Hikvision NVRs will reproduce more details. The Super
Series can display up to 68-ch video at 1080p, the I-Series can display up to 16-ch video at
1080p, and the K-Series can display up to 8-ch video at 1080p.
Multi-Video Output
• Independent Outputs: Multiple outputs can display various channels independently
• Synchronous Outputs: The same channel displays at different locations synchronously
Video Wall
Video wall functionality expands and extends the use
of conventional monitors. More channels and more
functions come to life, enhancing video surveillance
capabilities and giving security personnel the upper
hand in their daily operations.

Embedded Linux System
Dual Systems
Our NVRs have two copies of the firmware in the
flash, so if one of the flash sections ceases, the
redundant firmware will operate in its place.
N+1 Hot Spare
Emergency Scenario:
• When working NVR X breaks down, the standby
NVR will take over NVR X to keep the system
working on.
• Standby NVR – After network recovers, recorded
video transfers back to NVR 1 (the backup NVR
can only take over one offline device at a time)

Automatic Network Replenishment (ANR)
Emergency Scenario:
• Network breaks down
• Video recording switches to SD Card in IP camera
• After network recovery, recorded video retransfers back to NVR

04 Easy to Use
Super POE
Hikvision’s “Super” Power-over-Ethernet capability (POE) reduces installation and configuration headaches as well as
material costs. No need to lay power cables or to configure IP addresses for each camera! Everything is ready to go!
What’s more, with Super POE, you’ll get 300 meters of power and video transmission, versus only 100 meters in the
previous design.
Dual NICs
The Dual-NIC feature provides two isolated network interfaces, so customers can configure LAN & WAN surveillance
according to their particular application and needs.
Virtual Host
For remote users, this function offers an easy way to configure IPC parameters connected to the PoE port even when
the IPC has not been allocated an IP address.

Easy Search
In this mode, users can search video from
a selected channel. Like its name, it makes
searching through video easier than ever.
Easy Playback
In preview mode, users can replay video from a selected channel.
The NVR supports several Smart playback modes:
• Smart: Skip static images and play back periods containing the target event
• Sub-periods: Cut an extended time period into several short periods; play back any short time period in several different
channels at the same time.
Video Abstraction
In this playback mode, the NVR will condense one day of video into ten or twenty-minutes. Events occurring at various
times can be shown in the same image, radically reducing the time required to locate a single event.
Multi-Screen Output
The NVR has up to four different output interfaces
and various users can control or preview the same
NVR from different locations.

After DeepinMind NVR processes images, the false alarms are filtered out!
Imagine a radically new and powerfully intelligent video recording device from Hikvision. An NVR with the power to
overhaul any video surveillance system. This is it.
Hikvision’s DeepinMind Series NVR Model #iDS-9632NXI-I8/16S is the first embedded NVR based on a deep learning
algorithm executed by its GPU, making it faster and more accurate than conventional CPUs. This NVR effectively filters
out alarms triggered by animals and inanimate objects, with greater than 90% accuracy.
Deep learning has come to the security industry in this amazing video recording unit.
Hikvision’s DeepinMind NVR integrates beautifully with economical IP cameras as an intelligent filter solution.
Integrating this NVR into an existing security system will radically advance its capabilities in one simple step. Continue
reading to see how this might be possible.
06 Other Features
Network Application Enhancement
Channel Zero and Transcode: With channel-zero function, users can view up to 16 cameras connected to an NVR but only use
one channel’s worth of bandwidth. The transcode function reduces the stream data by reducing the resolution, bitrate, or
framerate. In poor network environments, the Channel-Zero function helps to ensure fluid video for remote users. For mobilephone users, this function can also reduce charges.
Hik-Connect App management provides privacy, security, convenience, & efficiency – all in one!
Anywhere, anytime, across the entire system.
Third Party Compatibility
Hikvision NVRs support over 20 common third-party camera protocols.
Online search for Hikvision and Third-Party IP Cameras reveals multiple methods for adding cameras:
manual, one-touch, and custom configurations.
Abstract playback Dual-stream Transcode Channel Zero
Hikvision NVRs can connect
to a third-party IP camera via
ONVIF protocol. Our Embedded
NVRs support third-party device
integration. We provide third-party
integrators with SDK and ISAPI
protocol documents. The NVRs also
support standard ONVIF protocols.
ONVIF protocol creates a standard for how IP products within video surveillance
and other physical security areas can communicate with each other.
