HD-TVI DVR: Hikvision iDS-7216HUHI-M2/X(STD) (16-ch, 8 MP, 8 fps, H.265, 8 x AcuSence, HDMI, VGA)

Hikvision iDS-7216HUHI-M2/X s a 16-channel, multi-system DVR capable of recording video from cameras: HD-TVI, AHD, CVBS and IP.
The DVR for an analog system can record images with the following resolution and frame rate:

In a standard mode of operation, 16 analog cameras can be connected to BNC inputs, as well as 8 IP cameras with a resolution of up to 8 MP. If any of the analog channels are not used, they can be turned off, allowing additional IP cameras to be connected. f all analog channels are disabled, as many as 24 IP cameras can be connected.

Activating Enhanced IP mode increases the number of supported IP channels. It is possible to support up to 16 IP cameras with a resolution of 4 MP (the number of cameras can be expanded to 32, if all analog channels are disabled).

In Enhanced IP mode, the Intelligent Events (IVS) function on analog channels is disabled, and the resolution of HDMI/VGA video outputs is limited to 1080p. To activate this mode, direct access to the DVR menu is required.

The DVR can perform the following AI functions: motion detection 2.0 (8 channels) or perimeter protection (8 channels) or face detection and recognition (4 channels).

Motion Detection System 2.0 can analyze motion detection events for human or vehicle detection. Thanks to that, alarm notifications are filtered and unnecessary alarms are blocked.

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.

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. This model of DVR has 8 channels with AcuSense function.

On eight analog channels, it is possible to run virtual line crossing detection (together with line crossing direction determination) and intrusion detection in a quadrant area. Events can be filtered for human or vehicle detection.

The DVR can record one or two video streams (primary and/or secondary) from each channel. The video can be compressed using the H.265 method. Compared with its predecessor (H.264), H.265 can reduce the data stream by half, which translates into proportional disk space savings and extended data retention time. H.265+ can further minimize the streams in typical video surveillance scenarios.

The iVMS 4200 client software enables users to manage Hikvision devices in IP networks. The software enables the configuration and management of NVRs/DVRs, IP and analog cameras in hybrid systems. The iVMS 4200 utility can remotely manage up to 256 devices on up to 4 monitors. One monitor can display images from up to 64 cameras. Aside from system configuration and live monitoring, the utility can be used for remote playback, notifications, two-way audio transmission, and multi-level e-maps.

Hik-Connect is a mobile application designed for cell phones based on Android and iOS operating systems. It can be used to remotely view live video from DVRs, NVRs, network cameras using the Wi-Fi, 2G or 3G and also to view recordings stored on the DVR. The application allows connectivity via IP addresses and via P2P cloud.

Hik-Connect is also the name of a network service intended for Hikvison devices. The service relies on P2P cloud computing for remote viewing via smartphones and tablets, and provides extensive monitoring and basic configuration options: live viewing (multiple channels), PTZ control, digital zoom, acoustic monitoring, playback of archival video, and alarm notifications (intrusion, line crossing, etc.).

Main features of the Hik-Connect service:

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.
