Hikvision DS-7716NXI-I4 / S este un înregistrator IP modern cu 16 canale , care înregistrează imagini de pe camerele IP cu o rezoluție de 12 MP . HDMI 2 independent (rezoluție de până la 4K) și VGA (rezoluție de până la 1080p) vă permit să conectați două monitoare. Vizualizarea de pe fiecare poate fi configurată independent, diferite diviziuni de ferestre și sunt posibile, iar imaginea de la orice cameră poate fi afișată pe fiecare dintre ele. 4 porturi SATA permit conectarea hard disk-urilor cu o capacitate de până la 10 TB fiecare. Dacă memoria este plină, suprascrierea automată este declanșată pentru a preveni pierderea ultimelor date. Porturile încorporate USB vă permit să conectați o unitate flash USB sau un disc extern și să copiați fragmente specifice pe suporturi de date externe.

The recorder supports the AcuSense technology, which allows you to filter human/vehicle type objects. For cameras with a resolution of up to 2 MP not supporting AcuSense, this function can be performed by the recorder. When cameras with AcuSense are connected to the recorder, they will work with all channels with the maximum supported 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.

Artificial intelligence plays a key role in CCTV systems. Cameras and recorders with AcuSense technology analyze the image based on a deep learning algorithm. They reflect the structure and principles of the human brain. As in the brain, learning creates connections between artificial neurons (programs) and creates a multi-layer artificial neural network. The algorithm individually analyzes model photos and recordings, looking for common features, and then creates appropriate connections. The so-called layers, responsible for detecting a specific feature, are built this way. The more layers an algorithm has, the more accurate the analysis is. Therefore, teaching with large amounts of data is crucial. Only multi-layer networks can collect information and perform appropriate actions, in particular automatic extraction and representation of features (patterns) present in the data, teaching the network for example to recognize faces, vehicle brands, animal species or incident, e.g. a fall. The presented recorder model has two key AI functions, which include:

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. The model of recorder described has an option of filtering false alarms of a human/vehicle objects in 4 channels, enabling the classification of objects according to the silhouette of a person or a vehicle (for cameras not supporting the AcuSense). Once the AcuSense cameras are connected, they will be fully supported in all channels. This type of solution allows for an effective reduction of false alarms and quick search for the registered ones

The recorder has 4 channels to which cameras with the face capture function can be connected. If the cameras do not support this function, it can be run by the recorder in 1 channel. Up to 16 face libraries can be created in the recorder based on which the control will be performed. It is also possible to upload a photo from the outside in order to search the database.

Compresia este un parametru foarte important care demonstrează avansarea dispozitivului. Cu cât este mai bună compresia, cu atât este mai mică cerința de lățime de bandă cu aceeași calitate subiectivă. H.265 (HEVC - High Efficiency Video Coding) este în prezent cea mai eficientă metodă de compresie. În comparație cu predecesorul său (H.264), reduce fluxul de date și cererea de capacitate a discului la jumătate. Prin urmare, pot fi utilizate hard disk-uri cu o capacitate înjumătățită sau înregistrările pot fi stocate de două ori mai mult. Versiunea sa îmbunătățită H.265 + a fost optimizată pentru utilizare în sistemele de monitorizare CCTV. Acestea permit reducerea în continuare a fluxurilor de date.

H.265 / H.265 + - rapoarte de compresie mai ridicate cu păstrarea calității video oferite de H.264

iVMS-4200 is client software dedicated to the management and supervision of Hikvision security systems, such as recorders (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.

Hikvision devices can be operated via mobile phones with Android or iOS using the dedicated Hik-Connect mobile application. It can be used for remote live viewing from DVRs, NVRs, IP cameras, video intercoms over the WiFi, 2G or 3G and to view saved recordings. Operating video intercoms with the application provides also remote opening of the electric strike, receiving notifications and transferring calls from the entrance panel to the phone in the absence of the subscriber. The application supports connectivity over IP and a P2P cloud. Hik-Connect is also the name of the cloud service that provides 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.

Various applications intended for the installers and operators/users of video surveillance systems based on Hikvision devices are described in our library.

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.
