Hikvision DS-7608NXI-I2/4S is a modern IP network video recorder capable of monitoring, recording and playing back images from 8 IP cameras of megapixel resolutions, up to 12 MP. Its independent VGA (up to 1080p) and HDMI (up to 4K) monitor outputs can provide images with different layouts. Each monitor can display the video from any camera, in any screen division. Two SATA ports enable the user to install 2 hard drives, each with capacity up to 8 TB. In the case of disk space overflow, the newest data overwrites the oldest recordings. Built-in USB ports allow for connecting external memory sticks or disk drives in order to copy some files.
AcuSense
The DS-7608NXI-I2/4S NVR uses AcuSense technology based on Hikvision Deep Learning Algorithms. In traditional monitoring systems, video analytics and object detection is based on changes in pixels. This approach is the source of a significant amount of false alarms caused, for example, by the movement of trees in the wind, rainfall, or changes in lighting. AcuSence technology with the deep learning algorithms introduces a new approach in monitoring systems, focused on efficient detection of threatening events with minimizing the number of false alarms.
The filters of false alarms are available in four channels, for using with cameras without AcuSense technology. They classify objects according to human figures and vehicle shapes. Currently, the use of this functionality is possible for VCA events such as crossing virtual lines and/or encroaching on intrusion-protected areas. Cameras with AcuSense technology can be connected to any channels and are fully supported. Thanks to the proper recognition, the system can filter out even 90% of events that would trigger false alarms, which significantly increases the accuracy and effectiveness of alerting and contributes to lowering the workload of the operator(s) and costs of sending intervention groups.

H.265+ video compression
H.265/H.265+ - higher compression ratios with preserving video quality provided by H.264
The local recording and network transmission can use H.265+, H.265, H.264+ or H.264 compression methods that provide good image quality with relatively small bandwidth and disk space consumption (in each case the selected type of compression must be supported by the cameras). Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios. To use any available compression method, it must be supported by the connected cameras. The compression method can be specified individually for each channel.
Intelligent image analysis
The NVR supports alarms generated by VCA functions (face detection, license plate recognition, crossing virtual lines, area intrusion detection, an entry/exit to/from an area, loss of focus, etc.) implemented in cameras. The response to such an event (e.g. someone crosses virtual line in a specified direction) can be the change of the state of the alarm output, email notification sent to a monitoring center etc., depending on the configuration. Advanced analytics allows installers/users to implement more advanced projects, perform quick search of interesting events and preset intelligent recording that saves disk space.
Guarantee of continuous recording
With the support of ANR (Automatic Network Replenishment), any IP camera equipped with a memory card can record video in the absence of network connection. After the restoration of the network connection, the recordings are automatically synchronized with those recorded on the NVR. This ensures continuous coverage of events, even in the case of communication problems between the camera and NVR.
Special recording modes
IP CCTV systems based on Hikvision IP cameras and NVRs can be configured for continuous recording with special parameters in the case of specific events. Each channel can be configured individually in this aspect. It is possible to increase the frame and bit rates, independently of the continuous recording settings. After the occurrence of an event (motion detection, camera tampering etc), the NVR automatically switches to the event-recording mode (usually with higher parameters). During the rest of the time the recording is carried out in the continuous mode. The increased parameters just before and after the event allow to play back every second of the period with high detail and smoothness, while the recordings between events may have a much lower performance, taking significantly less space on the storage media.
Refined client software
The iVMS 4200 client software enables users of HIKVISION devices to manage them in IP networks. The software allows for configuration and management of NVRs/DVRs, IP and analog cameras (in hybrid systems). The iVMS 4200 utility can remotely manage up to 256 devices, with the use of up to 4 monitors. One monitor can display up images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifying, two-way audio transmission, creating multi-level e-maps.

Hik-Connect is a mobile application, intended for smartphones running Android or iOS operating systems. It can be used for remote live viewing of images from DVRs, NVRs, network cameras via Wi-Fi, 2G or 3G networks, and for playing back recorded video files. The application connects with the devices by IP addresses and/or through the P2P cloud.

Working in the cloud
Hik-Connect is also a network service for Hikvison devices. The service is based on data processing in the cloud and integrates the following functions:
  • Remote access through the cloud - it allows access to the device without having an external IP address and when simplicity is the most important thing. Only the basic configuration of the network is required. The application on a PC or smartphone connects with the device via P2P cloud service,
  • DDNS server - DDNS assigns a fixed domain name to dynamically changing IP addresses (Dynamic DNS). This feature is useful when the ISP does not provide users with a fixed IP address. The condition for using DDNS is having a public IP address and providing access from the external network to the appropriate ports of the NVR (server and http, by default 8000 and 80). The connection is possible via a web browser, client application on a PC and on smartphones.
Advanced applications for organizing and operating CCTV systems
This article provides an overview of applications dedicated for installers and users of Hikvision-based video surveillance systems.
Main window of SADP application
SADP (Search Active Device Protocol) is a free and simple to use utility for searching Hikvision IP cameras and Hikvision DVRs/NVRs in the local network. The network device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords. Detailed information on the software and its use is contained in the SADP application - LAN tool for organizing CCTV systems based on Hikvision devices article.
