NVR 4K 32 canale Hikvision DS-7732NXI-I4/S(C) (256 Mbps, 4xSATA, VGA, VGA, HDMI, BNC, H.264)

NVR-ul 4K DS-7732NXI-I4/S(C) este un înregistrator IP modern capabil să monitorizeze, să înregistreze și să redea imagini de la 32 de camere IP cu rezoluții de până la 12 MP. Ieșirile video independente HDMI (până la 4K) și VGA (până la 1080p) pot furniza imagini cu layout-uri diferite. Fiecare monitor poate afișa imagini de la orice cameră, în orice divizie a ecranului. Patru porturi SATA permit utilizatorului să instaleze 2 HDD-uri, fiecare cu o capacitate de până la 10 TB. În cazul depășirii spațiului pe disc, cele mai noi date sunt suprascrise peste cele mai vechi înregistrări. Porturile USB încorporate permit conectarea unităților de memorie externa pentru a copia unele fișiere.

Înregistratorul este echipat cu funcția AcuSense , care permite să filtrați obiecte de tip uman/vehicul. Pentru camerele cu o rezoluție de până la 2 MPix care nu acceptă AcuSense, această funcție poate fi îndeplinită de înregistrator. Dacă dotiți să conectați camere cu tehnologie AcuSense, acestea vor fi suportate pe toate canalele la rezoluția maximă acceptată. Datorită recunoașterii precise, sistemul poate filtra aproape toate alarmele false. Înregistratorul are, de asemenea, opțiunea de analiză și detectare a feței, care poate fi efectuată pe 4 canale. Puteți să creați până la 16 biblioteci de fețe pe baza cărora va fi implementat controlul. Capacitatea de a compara fețele vă permite să găsiți rapid o anumită persoană protecția perimetrului și analiza facială nu pot funcționa în paralel. Suportul pentru camere dedicate identificării numerelor de înmatriculare ANPR, camerelor PTZ, analizei VCA și posibilitatea integrării cu case de marcat fiscale folosind sistemul POS, permite înregistratorului să fie utilizat pentru a implementa o gamă largă de proiecte. Opțiunile inteligente pentru căutarea și analiza înregistrărilor permit să găsirea rapidă a evenimentelor căutate.

The DVR 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 DVR 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 DVR 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.
