NVR 8 canale 4K Hikvision DS-7608NXI-I2/S(C) 80 Mbps, 2xSATA, 4xAcuSense, detecție facială, H.265

Hikvision DS-7608NXI-I2/S(E) is a modern 8-channel IP recorder, recording image from IP cameras with a resolution of 32 MP. Independent HDMI (resolution up to 4K) and VGA (resolution up to 1080p) allow you to connect two monitors. The view on each output can be configured independently, different window divisions and are possible and the image from any camera can be displayed on each of them. 2 SATA ports enable connection of hard drives with a capacity of up to 14 TB each. If the memory is full, automatic overwriting is triggered to prevent the loss of the latest data. The built-in USB ports allow you to connect a USB flash drive or external disk and copy specific fragments to external data carriers.

The recorder supports the Motion detection 2.0 and AcuSense technology, which allows you to filter human/vehicle type objects. It can support motion detection 2.0 cameras or implement this functionality on all channels when connecting regular Hikvision IP cameras. Perimeter protection with human/vehicle object filtering function can be supported on all channels when connected to cameras with AcuSense functionality, and can be implemented by the NVR on 4 channels when connected to a regular IP camera with up to 2 MP resolution. Thanks to accurate recognition capability, the system can filter out almost all false alarms. The recorder has also the option of face analysis and detection, which can work in 4 channels. It is possible to create up to 16 face libraries based on which the control will be performed. The ability to compare faces allows you to quickly find a specific person (perimeter protection and face analysis cannot work in parallel). Support for cameras dedicated to identifying license plates ANPR, PTZ cameras, VCA analysis and the possibility of integration with cash registers using POS allows the recorder to be used for projects with various advancement levels. Intelligent options for searching and analyzing recordings allow you to quickly extract a fragment of interest from the recorded footage.

The NVR has a function to capture and analyze faces on a certain number of channels. It is possible to create libraries of faces that will later be used to search the recordings. Related actions can also be specified that will be executed in case of a correct or incorrect comparison between a detected face and a face that is in the library, such as triggering a beep in the recorder, an alarm in the monitoring center, sending an e-mail, controlling an alarm output, etc. Faces, already recorded on the DVR or from an external source, can be added to the library. Recordings stored on the DVR, can be easily and quickly searched after pointing to a specific face, on channels on which the face recording and comparison function was active.

The NVR can be connected to all channels with cameras equipped with the motion detection 2.0 algorithm. It allows to effectively reduce the number of false alarms thanks to the classification of human and vehicle type objects. Recordings stored on the DVR, can be easily and quickly searched for human or vehicle type criteria. If cameras with a traditional motion detection algorithm are connected to the DVR their functionality can be extended by the DVR to motion detection 2.0 in the number of channels indicated in the specifications of a particular model.

The NVR supports perimetric protection in the form of VCA events (e.g., line crossing, intrusion detection, entering and exiting an area) generated by Hikvision IP cameras, which is enhanced with AcuSense technology. The protection can be supported on all channels if AcuSense cameras are connected, or implemented by the DVR on the number of channels specified in the DVR specification if regular IP cameras are connected. Perimeter protection ensures early detection of people who intend to violate the protected area. When building a security system, its resistance to false alarms, triggered by e.g. animals, moving trees, leaves, shadows, weather conditions, etc. is extremely important. Ideal for such surveillance applications are cameras and recorders with the AcuSense technology which analyzes objects based on the Deep Learning algorithm, considering events meeting certain criteria as real threats.

Compression is a very important parameter proving the device advancement. The better the compression, the lower the bandwidth requirement with the same subjective quality. H.265 (HEVC - High Efficiency Video Coding) is currently the most efficient compression method. Compared to its predecessor (H.264), it reduces the data stream and the demand for disk capacity by half. Therefore, hard drives with a halved capacity can be used, or recordings can be stored for twice as long. Its improved version H.265+ has been optimized for use in CCTV monitoring systems. They allow for further reduction of data streams.

iVMS-4200 is client software dedicated to the management and supervision of Hikvision security systems, such as DVRs (IP, TurboHD), video intercoms, access control, set-top boxes, etc. The software allows you to easily and conveniently monitor all systems by offering viewing from IP cameras, remote playback of recordings, remote configuration, handling of alarm events, two-way audio transmission, e-map support, recording to a HDD and many more.

A mobile application Hik-Connect is dedicated to operate Hikvision devices using cell phones with the operating system Android or iOS. It can be used to remotely view live video from DVR, NVR, network cameras, video intercoms using Wi-Fi, 2G or 3G networks as well as to view recorded video. Video intercoms can be operated with the application which additionally allows for remote opening of electric doors, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the resident. The application supports connectivity via IP and the P2P cloud. Hik-Connect is also the name of a cloud-based service that allows access to devices in the absence of an external IP address.

The image from the IP camera is sent to the recorder as a data stream. Thanks to the support of the ANR (Automatic Network Replenishment) function, the Hikvision IP camera equipped with a microSD card can save recordings on it in the event of network failure, i.e. problems with communication between the camera and the recorder. After the problem is solved, the recordings are automatically synchronized with the recorder and marked with a different color on the playback bar. Such a solution guarantees the continuity of recordings and boosts the entire system performance.

Our library provides an overview of applications dedicated for installers and users of monitoring systems based on Hikvision devices.

SADP (Search Active Device Protocol) is a free, easy-to-use utility designed to search for Hikvision IP cameras and DVRs/NVRs in the local network. The network device search tool can also be used to modify device network parameters, e.g. to change or recover default passwords. Detailed information on the software, its use and password recovery (par. 8) can be found in the following article: SADP application - LAN tool for organizing CCTV systems based on Hikvision devices.
